[0037] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The schematic diagram of the structure of the cooking device 100 in one embodiment of the present application is shown. The cooking device 100 provided in one embodiment of the present application can be a steamer, a steam oven, etc., or any other existing device with a cooking function, without limitation. Figure 1 and Figure 2 As shown, the cooking device 100 includes an inner pot 110 and a heat exchange assembly 120, wherein the inner pot 110 includes a cooking cavity 111 with an opening, and the cooking cavity 111 is used to place and cook food. The inner pot 110 also includes a back plate 112, which is located on the side of the cooking cavity 111 away from the opening.

[0038] like Figures 1 to 3 As shown, the heat exchange assembly 120 includes a water tank 121 and a heat exchange plate 122, wherein the heat exchange plate 122 is connected to the side of the back plate 112 away from the cooking cavity 111, and a hollow cavity is formed between the heat exchange plate 122 and the back plate 112 so that the two together enclose a heat exchange cavity 123.

[0039] like Figures 3 to 5 As shown, in one embodiment, at least one of the heat exchange plate 122 and the back plate 112 is provided with a groove on the end surface facing the other of the heat exchange plate 122 and the back plate 112 to form a heat exchange cavity 123. In this embodiment, as shown in FIG. Figure 3 and Figure 4 As shown, the end surface of the back plate 112 facing the heat exchange plate 122 is concavely provided with a first groove 1121, and as shown in FIG. Figure 4 and Figure 5 As shown, the end surface of the heat exchange plate 122 facing the back plate 112 is concavely provided with a second groove 1221, and the first groove 1121 and the second groove 1221 together form a heat exchange cavity 123. In other embodiments, the back plate 112 may be provided with a groove to form the heat exchange cavity 123, or the heat exchange plate 122 may be provided with a groove to form the heat exchange cavity 123.

[0040] like Figure 3 and Figure 4As shown, a water storage chamber 1211 is provided in the water tank 121, and the heat exchange chamber 123 and the water storage chamber 1211 are connected to allow water to circulate between the heat exchange chamber 123 and the water storage chamber 1211, so that the circulating water inside the heat exchange chamber 123 can exchange heat with the steam inside the cooking chamber 111 of the inner pot 110, thereby reducing the content of hot steam in the cooking chamber 111, and solving the problem of a large amount of steam remaining in the cooking chamber 111 after the cooking work of the cooking device 100 is completed.

[0041] In one embodiment, the end surface of the back plate 112 facing the heat exchange plate 122 is sandblasted to make its surface rough, so as to reduce the speed of water flowing on the surface of the back plate 112, thereby increasing the time of heat exchange between the water flow and the back plate 112, thereby increasing the anxiety of lowering the temperature of the inner tank 110.

[0042] like Figure 3 and Figure 4 As shown, in one embodiment, the heat exchange assembly 120 includes a water inlet pipe 124 connecting the heat exchange chamber 123 and the water storage chamber 1211 and a pump body 125 connected to the water inlet pipe 124. The pump body 125 acts on the water flow in the water inlet pipe 124 and can drive the water flow from the water storage chamber 1211 to the heat exchange chamber 123, so that the water in the water tank 121 can enter the heat exchange chamber 123, thereby cooling the inner pot 110. It can be understood that only when the pump body 125 is working can the water flow in the heat exchange chamber 123 and the water storage chamber 1211 be circulated, and whether the pump body 125 is turned on can be set according to the working condition of the cooking device 100. For example, after the cooking device 100 finishes cooking, the pump body 125 starts to work to cool the cooking chamber 111 after cooking is completed, without interfering with the cooking of the food by the cooking device 100.

[0043] like Figure 3 and Figure 4 As shown, the heat exchange plate 122 includes a plate body 1222 and a water inlet 1223. The plate body 1222 is partially attached to the back plate 112 and together with the back plate 112, forms a heat exchange cavity 123. In this embodiment, the water inlet 1223 is a box-shaped structure covering the plate body 1222. The water inlet 1223 is provided with a water inlet space 12231 connected to the water inlet pipe 124. In this embodiment, the water inlet 1223 and the plate body 1222 are together formed to form the water inlet space 12231. The plate body 1222 is provided with a water inlet hole 12221 connecting the water inlet space 12231 and the heat exchange cavity 123. The position of the water inlet hole 12221 corresponds to the position of the water inlet 1223. In this embodiment, as Figure 3 and Figure 5 As shown, the water inlet 1223 is horizontally arranged and laterally covers the heat exchange cavity 123, and as shown Figure 5As shown, there are multiple water inlet holes 12221, and all of the water inlet holes 12221 are distributed in an array so that when water flows into the heat exchange cavity 123, it can cover as much as possible laterally, so that the temperature of each location in the lateral direction of the cooking cavity 111 in the inner pot 110 is uniformly reduced.

[0044] like Figure 4 As shown, in this embodiment, the cross-sectional area of ​​the water inlet space 12231 gradually decreases in the direction toward the water inlet hole 12221 to pressurize the water flow. Figure 4 As shown, the water inlet part 1223 includes two interconnected spaces, which together form a water inlet space 12231, and the volume of the space close to the water inlet hole 12221 is smaller than the volume of the space away from the water inlet hole 12221, and the water inlet pipe 124 is connected to the space away from the water inlet hole 12221 to achieve a certain pressurization effect, so that the water flow can be sprayed toward the back plate 112.

[0045] In one embodiment, the water inlet 1223 is disposed at the top of the plate 1222 or at the top of the end surface of the plate 1222 facing away from the back plate 112. Figure 3 and Figure 4 As shown, in this embodiment, the water inlet 1223 is located at the top of the end surface of the plate body 1222 away from the back plate 112, and accordingly, the water inlet is located at the top of the side wall of the heat exchange chamber 123. In other embodiments, the water inlet 1223 can also be provided at the top of the body, and accordingly, the water inlet is located at the top of the heat exchange chamber 123.

[0046] like Figure 1 and Figure 4 As shown, in one embodiment, the water tank 121 is located on the side of the heat exchange plate 122 away from the back plate 112. In this embodiment, the cooking device 100 also includes an upper mounting plate 140 located above the inner pot 110 and a lower mounting plate 150 located below the inner pot 110, and the water tank 121 is installed on the lower mounting plate 150.

[0047] like Figure 3 and Figure 4 As shown, the bottom end of the plate body 1222 is provided with a water outlet 1224 connected to the heat exchange chamber 123. Preferably, the water outlet 1224 is located at the bottom end of the heat exchange chamber 123. More preferably, as Figure 5 As shown, the bottom surface of the heat exchange chamber 123 is an inclined surface inclined at a downward slope toward the water outlet 1224 to converge the water flow in the heat exchange chamber 123 .

[0048] like Figure 3 and Figure 4As shown, the water tank 121 is provided with a water return port 1212 which is arranged in a position opposite to the water outlet 1224 and is connected to the water storage chamber 1211, so that the water flows from the heat exchange chamber 123 back to the water storage chamber 1211 through the water outlet 1224 and the water return port 1212, so that the water flow in the heat exchange chamber 123 can naturally flow back to the water storage chamber 1211 under the action of gravity, thereby realizing water circulation between the water tank 121 and the heat exchange chamber 123. In this embodiment, the water return port 1212 is provided on the top surface of the water tank 121, and in other embodiments, the water return port 1212 can also be provided on the side wall of the water tank 121.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the cooking device 100 further includes a door body 130, which covers the inner pot 110, and when the door body 130 covers the inner pot 110, the door body 130 covers the opening of the cooking cavity 111 to make the cooking cavity 111 a sealed cooking space, thereby facilitating cooking ingredients.

[0050] like Figure 6 As shown, the door body 130 includes an outer plate 131 and an inner plate 132 arranged at intervals, and the interval between the outer plate 131 and the inner plate 132 forms an inner door space 133. It can be understood that a side plate 136 is also arranged between the outer plate 131 and the inner plate 132, and the outer plate 131, the inner plate 132 and the side plate 136 are enclosed together to form an inner door space. Figure 6 As shown, the door body 130 also includes a fan 134 arranged in the door inner space 133, and the inner plate 132 is provided with a blowing hole 1321 connecting the door inner space 133 and the cooking cavity 111, so that the fan 134 blows the air flow through the blowing hole 1321 toward the inside of the cooking cavity 111, and because the fan 134 is located on the side of the cooking cavity 111 with an opening, it can drive the air flow in the cooking cavity 111 to flow in a direction away from the opening, that is, close to the back plate 112, so as to achieve the steam inside the cooking cavity 111 is blown to the back plate 112 of the inner pot 110 for heat exchange with the water flow in the heat exchange cavity 123, so that when the door body 130 is opened, the steam inside the cooking cavity 111 has been at least partially condensed into water, thereby reducing the instantaneous diffusion of hot steam when the door body 130 is opened.

[0051] like Figure 6 and Figure 7 As shown, in one embodiment, the fan 134 is located at the top of the door inner space 133, as shown in FIG. Figure 7 and Figure 8 As shown, the door body 130 further includes an air guide plate 135 located in the door inner space 133, one end of the air guide plate 135 is connected to and at least partially wraps the air outlet of the fan 134, and the other end extends toward the bottom of the door inner space 133, and the air guide plate 135 and the outer plate 131 are together enclosed to form an air guide cavity 1352 with an open bottom. Figure 6and Figure 8 As shown, in this embodiment, the width of one end of the wind guide plate 135 connected to the air outlet of the fan 134 is gradually reduced to wrap the fan 134, and the wind is guided by a structure that gradually expands from the fan 134 to the bottom, so that the wind of the fan 134 can be diffused in the entire wind guide cavity 1352. Figures 6 to 8 As shown, the air guide plate 135 is provided with an air vent 1351 aligned with the air hole 1321 , so that the air flow in the air guide cavity 1352 can enter the cooking cavity 111 through the air vent 1351 and the air hole 1321 .

[0052] like Figure 6 and Figure 7 As shown, in one embodiment, the door body 130 also includes a bottom plate 137 located below the air guide plate 135, the bottom plate 137 is located on the open air outlet path at the bottom end of the air guide cavity 1352, and the bottom plate 137 is provided with an exhaust port 1371 connected to the outside of the door body 130, so that the airflow in the air guide cavity 1352 can flow from top to bottom, and be discharged from the door body 130 through the air guide cavity 1352 and the exhaust port 1371 from the fan 134, thereby achieving cooling of the door body 130.

[0053] like Figures 7 to 9 As shown, in one embodiment, the door body 130 further includes a baffle 138, and the baffle 138 is rotatably connected to the air guide plate 135. Figure 7 As shown, the baffle 138 is located on the flow path between the fan 134 and the bottom opening of the air guide cavity 1352 and is located downstream of the vent 1351. The area of ​​the air guide plate 135 is not less than the cross-sectional area of ​​the flow path between the fan 134 and the bottom opening of the air guide cavity 1352. Figure 7 The shielding position of the shielding vent 1351 indicated by the solid line is Figure 7 The middle dotted line indicates that the fan 134 is at least partially blocked from rotating between the flow passage between the bottom opening of the air guide cavity 1352. Figure 7 As shown, when the baffle 138 is in the shielding position to shield the vent 1351, the airflow in the air guide cavity 1352 in the door body 130 can flow from top to bottom, and is discharged from the door body 130 through the air guide cavity 1352 and the exhaust port 1371 from the fan 134, thereby cooling the door body 130. Figure 7 As shown in the middle dotted line position, when the baffle 138 is in the blocking position, the baffle 138 does not cover the vent 1351 but partially covers the flow path from the fan 134 to the bottom opening of the air guide cavity 1352, so that the airflow in the air guide cavity 1352 can enter the cooking cavity 111 through the vent 1351 and the blowing hole 1321, and can drive the airflow in the cooking cavity 111 to flow in the direction away from the opening, that is, towards the direction close to the back plate 112.

[0054] like Figure 7 and Figure 8 As shown, in the present embodiment, the area of ​​the air guide plate 135 is larger than the cross-sectional area of ​​the flow path between the fan 134 and the bottom opening of the air guide cavity 1352. When the baffle 138 is in the blocking position, it is tilted in the air guide cavity 1352. At this time, the baffle 138 has basically blocked the flow path between the fan 134 and the bottom opening of the air guide cavity 1352, so that the airflow in the air guide cavity 1352 basically flows out through the vent 1351. Theoretically, in other embodiments, regardless of whether the area of ​​the air guide plate 135 is larger than the cross-sectional area of ​​the flow path between the fan 134 and the bottom opening of the air guide cavity 1352, or the area of ​​the air guide plate 135 is equal to the cross-sectional area of ​​the flow path between the fan 134 and the bottom opening of the air guide cavity 1352, when the cooperation between the baffle 138 and the air guide plate 135 is a sealed cooperation and the baffle 138 can rotate to cover the flow path, the baffle 138 can completely block the flow path between the fan 134 and the bottom opening of the air guide cavity 1352, so that all the airflow in the air guide cavity 1352 flows out through the vent 1351.

[0055] like Figures 6 to 9 As shown, in one embodiment, the door body 130 further includes a driving component 139, which is used to drive the baffle 138 to rotate relative to the air guide plate 135, and the driving member is configured to drive the baffle 138 to rotate to the shielding position when the temperature in the cooking cavity 111 is higher than the set temperature, and to drive the baffle 138 to rotate to the blocking position when the temperature in the cooking cavity 111 is lower than the set temperature, so that when the temperature in the cooking cavity 111 is high, for example, during the process of cooking food, the baffle 138 rotates to the shielding position to shield the vent 1351, and the airflow in the air guide cavity 1352 in the door body 130 can flow from top to bottom The air in the air guide cavity 1352 is moved, and the air is discharged from the fan 134 through the air guide cavity 1352 and the exhaust port 1371 to the door body 130, thereby cooling the door body 130; and when the temperature of the cooking cavity 111 is relatively low, for example, after the cooking of the ingredients is completed, the baffle 138 rotates to the blocking position. At this time, the baffle 138 does not cover the vent 1351 but partially covers the flow path between the fan 134 and the bottom opening of the air guide cavity 1352, so that the airflow in the air guide cavity 1352 can enter the cooking cavity 111 through the vent 1351 and the blowing hole 1321, and can drive the airflow in the cooking cavity 111 to flow in a direction away from the opening, that is, in a direction close to the back plate 112. It should be explained that the two set temperatures can be equal or different. In some embodiments, the driving member can be configured to be controlled by a temperature detection member, which starts working when it reaches a preset set temperature.

[0056] like Fig. 9As shown, in one embodiment, the driving assembly 139 includes a driving housing 1391, a push rod 1392 and a rotating member 1393. The push rod 1392 and the rotating member 1393 are connected in a transmission manner so that the rotating member 1393 rotates when the push rod 1392 moves. In this embodiment, a rack is provided at one end of the push rod 1392 extending out of the driving housing 1391, and the rotating member 1393 is a gear. The gear meshes with the rack so that when the rack moves back and forth, the gear rotates forward or reversely. The baffle 138 is connected to the rotating member 1393 and rotates synchronously with the rotating member 1393, so that when the push rod 1392 moves back and forth, it can drive the baffle 138 to rotate from the shielding position to the blocking position or from the blocking position to the shielding position.

[0057] like Figure 1 and Figure 6 As shown, the drive assembly 139 also includes a heat transfer member 1394 connecting the drive housing 1391 and the inner tank 110. Figure 1 As shown, the inner pot 110 is provided with a heating element 113, and the heating element 113 is used to heat the water in the inner pot 110 to form steam. The heat transfer element 1394 is connected to the heating element 113. When the heating element 113 is heated, the temperature in the cooking cavity 111 of the inner pot 110 naturally rises, so that when the cooking device 100 starts to cook food, the temperature of the driving housing 1391 rises as the temperature of the heating element 113 rises. Fig. 9 As shown, a storage chamber 1395 is provided in the driving housing 1391, and the temperature in the storage chamber 1395 changes in a positive correlation with the temperature in the cooking chamber 111. Since the volume of the storage chamber 1395 remains unchanged, the higher the internal temperature, the higher the internal pressure. The push rod 1392 is movably mounted on the storage chamber 1395 and as shown in FIG. Fig. 9 As shown, the drive housing 1391 is provided with a hole aligned with the push rod 1392, one end of the push rod 1392 is passed through the hole and extends out of the energy storage chamber 1395, and a sealed space is formed between the other end and the energy storage chamber 1395, so that the push rod 1392 can move when the air pressure in the energy storage chamber 1395 changes.

[0058] like Fig. 9 As shown, in one embodiment, the drive assembly 139 also includes an elastic member 1396, which is located in the energy storage chamber 1395 and connected to the push rod 1392. The elastic member 1396 has a tendency to drive the push rod 1392 to move in a direction opposite to the movement direction of the push rod 1392 when the air pressure in the energy storage chamber 1395 increases, so that when the temperature in the energy storage chamber 1395 decreases and the air pressure drops, the elastic member 1396 drives the push rod 1392 to reset.

[0059] The cooking device 100 provided in the above solution, when in use:

[0060] When the cooking device 100 starts to cook food, the heating element 113 of the inner pot 110 starts to work, and the heat transfer element 1394 connecting the drive shell 1391 and the heating element 113 transfers heat to the energy storage cavity 1395, so that the temperature inside the energy storage cavity 1395 begins to rise, thereby causing the air pressure in the energy storage cavity 1395 to increase, and pushing the push rod 1392 to move outside the energy storage cavity 1395. At this time, the push rod 1392 drives the rotating member 1393 and the baffle 138 to move synchronously, and the baffle 138 rotates to a shielding position to shield the air hole 1351. Under the action of the fan 134, the airflow in the air guide cavity 1352 in the door body 130 can flow from top to bottom, that is, it is discharged from the door body 130 through the air guide cavity 1352 and the exhaust port 1371 from the fan 134, thereby achieving cooling of the door body 130.

[0061] When the cooking device 100 finishes cooking, the pump body 125 acting on the water inlet pipe 124 starts, and drives the water in the water tank 121 to enter the heat exchange chamber 123 through the water inlet space 12231 and the water inlet hole 12221 to cool the temperature in the back plate 112 and the cooking chamber 111. At the same time, since the heating element 113 of the inner pot 110 stops working, the temperature in the energy storage chamber 1395 gradually decreases, and its internal pressure also gradually decreases. Under the action of the elastic member 1396, the push rod 1392 is reset, and the rotating member 1393 and the baffle 138 are driven to rotate, so that the baffle 138 rotates from the shielding position to the blocking position. The baffle 138 is positioned so that it does not cover the vent 1351 but partially covers the flow path from the fan 134 to the bottom opening of the air guide cavity 1352, so that the airflow in the air guide cavity 1352 can enter the cooking cavity 111 through the vent 1351 and the blowing hole 1321, and then drive the airflow in the cooking cavity 111 to flow in the direction away from the opening, that is, toward the back plate 112, so that the airflow in the cooking cavity 111 is fully in contact with the back plate 112 and the water flowing in the heat exchange cavity 123 on the back side of the back plate 112, thereby further accelerating the efficiency of the heat exchange component 120 in cooling the cooking cavity 111.

[0062] The cooking device 100 provided in the above scheme, by setting a heat exchange component 120 on the back plate 112 of the inner pot 110, utilizes the flowing water to exchange heat with the steam inside the cooking cavity 111 of the inner pot 110, thereby reducing the content of hot steam in the cooking cavity 111, and solving the problem of a large amount of steam remaining in the cooking cavity 111 after the cooking work of the cooking device 100 is completed, so that the hot steam has been at least partially condensed into water before the door is opened, thereby solving the problem of the existing cooking device 100 that the hot steam is released at the moment of opening the door after cooking, affecting the user experience and having a negative impact on the user's safety and the kitchen environment.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
