Description
TECHNICAL FIELD
[0001] The utility model relates to the related technical field of multifunctional cooking equipment, especially to a steam exhaust structure and multifunctional cooking equipment. BACKGROUND
[0002] Multifunctional cooking equipment with different functions such as steaming and baking, such as embedded steaming and baking oven, has different requirements for the steam exhaust effect of the inner container under different functions, and the requirements for the steam exhaust effect under different functions are relatively contradictory, for example:
[0003] When using the steaming function, the steam exhaust efficiency is required to be relatively low, and the water tank endurance can be improved as much as possible while ensuring the exhaust of the inner container; when using the baking function, the steam exhaust efficiency is required to be relatively high, so that the moisture in the food can be quickly exhausted to ensure the taste.
[0004] In order to balance the performance of the two, the traditional steaming and baking oven usually adopts multi-path steam exhaust or pressurized steam exhaust, the former sets two steam exhaust paths, one path for steam exhaust when steaming, and two paths for steam exhaust when baking, and realizes the on-off of one steam exhaust path by cooperating with motor, electromagnetic valve and other schemes; the latter increases the steam exhaust way, and adds air to the inner container to pressurize and accelerate the steam exhaust when baking;
[0005] However, the above methods need to increase electric control components on the basis of the original steaming and baking oven, which will inevitably increase the cost, and on the other hand, the motor, valve and pressurizing pump structure need to occupy a large space in the limited space, which is not conducive to the overall layout. INVENTION CONTENTS
[0006] Therefore, it is necessary to provide a steam exhaust structure and multifunctional cooking equipment which can meet the steam exhaust requirements under different modes, has relatively low cost and occupies relatively small space.
[0007] The application first provides a steam exhaust structure, which comprises a cooking inner container, a flue and a steam exhaust assembly, the steam exhaust assembly comprises a steam exhaust pipe and a baffle, the steam exhaust pipe is connected with the cooking inner container and the flue, the baffle is movably connected to the inner wall of the flue, so that the baffle has two states of closing and opening, and can switch between the two states with the change of the airflow size in the flue, wherein,
[0008] In the closed state, the baffle is attached to the steam exhaust pipe to block the outlet of the steam exhaust pipe; in the open state, the baffle opens the outlet of the steam exhaust pipe.
[0009] In one embodiment, the baffle is hinged to the inner wall of the flue.
[0010] In one of the embodiments, the baffle comprises a steam blocking plate and a driving plate, one of which is hinged to the inner wall of the flue, and in the closed state, the steam blocking plate is in contact with the exhaust pipe to block the outlet of the exhaust pipe, and the driving plate is located in the airflow path inside the flue to block the airflow.
[0011] In one of the embodiments, in the closed state, the driving plate is perpendicular to the airflow direction inside the flue.
[0012] In one of the embodiments, the inner wall of the flue is fixedly provided with a hinged bracket located above the exhaust pipe, and the steam blocking plate is hinged to the hinged bracket.
[0013] In one of the embodiments, a torsional spring is further connected between the hinged bracket and the steam blocking plate, which is used to drive the baffle to recover from the open state to the closed state.
[0014] In one of the embodiments, the hinged bracket is provided with two hinged seats in the horizontal direction, and the steam blocking plate is correspondingly provided with two hinged protrusions, and each hinged protrusion is hinged to one of the hinged seats.
[0015] In one of the embodiments, in the closed state, the baffle is in contact with the exhaust pipe to block at least part of the outlet area of the exhaust pipe.
[0016] In one of the embodiments, in the closed state, the baffle blocks the outlet area of the exhaust pipe, which accounts for one half of the total outlet area of the exhaust pipe.
[0017] The second aspect of the present application provides a multifunctional cooking equipment comprising the above-mentioned steam exhaust structure.
[0018] The above-mentioned steam exhaust structure sets the steam exhaust assembly between the cooking liner and the flue, so that the baffle can be adjusted between the open and closed states under the action of the airflow inside the flue, that is, the baffle can automatically adjust the state following the airflow intensity inside the flue, thereby meeting the steam exhaust demand of different cooking modes without adding additional electric control components;
[0019] Specifically, when the user uses the steaming function, the range hood fan starts in the weak gear, at this time, the airflow intensity inside the flue is relatively small, which cannot drive the baffle to move, so the baffle is in the closed state and blocks the outlet of the exhaust pipe to reduce the steam exhaust volume, thereby increasing the use duration of the steaming function under the premise of constant water tank volume.
[0020] When the user uses the roasting function, the range hood fan starts in the strong gear, at this time, the airflow intensity inside the flue is relatively large, and the baffle moves to the open state under the action of the airflow, so that the steam exhaust of the cooking liner is smooth, and the water in the food can be quickly exhausted, thereby ensuring the taste.

[0031] Please refer to Figure 1 And Figure 2 It is shown that the application first provides a steam exhaust structure, including a cooking liner 10, a flue 20 and a steam exhaust assembly 30, the steam exhaust assembly 30 includes a steam exhaust pipe 31 and a baffle 32, wherein the steam exhaust pipe 31 communicates the cooking liner 10 and the flue 20, the baffle 32 is movably connected to the inner wall of the flue 20, so that the baffle 32 has two states of closing and opening, and can switch between the two states with the change of the airflow size in the flue 20, wherein in the closed state, the baffle 32 is attached to the steam exhaust pipe 31 to block the outlet of the steam exhaust pipe 31;In the open state, the baffle 32 opens the outlet of the steam exhaust pipe 31.
[0032] It is not difficult to understand that according to different cooking modes of the cooking device, the exhaust hood fan connected with the flue 20 is in different operating power, so that the airflow intensity in the flue 20 is different; and in the present application, the steam exhaust assembly 30 is arranged between the cooking liner 10 and the flue 20, so that the baffle 32 can be adjusted between the open and closed states under the action of the airflow in the flue 20, that is, the baffle 32 can automatically adjust the state following the airflow intensity in the flue 20, so as to meet the steam exhaust demand of different cooking modes without adding additional electric control components.
[0033] Specifically, when the user uses the steaming function, the exhaust hood fan starts in the weak gear, at this time the airflow intensity in the flue 20 is relatively small, which cannot drive the baffle 32 to move, so the baffle 32 is in the closed state and blocks the outlet of the steam exhaust pipe 31 to reduce the steam exhaust amount, and increase the use endurance of the steaming function under the premise that the water tank volume is unchanged.
[0034] When the user uses the baking function, the exhaust hood fan starts in the strong gear, at this time the airflow intensity in the flue 20 is relatively large, and the baffle 32 moves to the open state under the action of the airflow, so that the steam of the cooking liner 10 can be exhausted smoothly, and the moisture in the food can be quickly exhausted, thereby ensuring the taste.
[0035] For the convenience of description, the force of the gas in the cooking liner 10 on the baffle 32 is defined as F2, the force of the airflow in the flue 20 on the baffle 32 is defined as F1, and the gravity of the baffle 32 itself is defined as F3.
[0036] Please refer to Figure 1 and Figure 2 It is shown that in some embodiments, the baffle 32 is hinged to the inner wall of the flue 20.
[0037] More specifically, when the user uses the steaming function, the cooking liner 10 is full of steam and presents a micro-pressure (that is, F2 is relatively small), and the exhaust hood fan is in the weak gear, the airflow intensity in the flue 20 is small (that is, F1 is relatively small), at this time F3 is greater than the resultant force of F2 and F1, and the baffle 32 is in the closed state.
[0038] When the user uses the baking function, the heating pipes and the air heater in the cooking liner 10 are started, the air is heated, the air in the cooking liner 10 has a force on the baffle 32 (that is, F2 is relatively large), and the exhaust hood fan is in the strong gear, the airflow intensity in the flue 20 is large (that is, F1 is relatively small), at this time F3 is smaller than the resultant force of F2 and F1, and the baffle 32 is in the open state.
[0039] Of course, in other embodiments, the baffle 32 can also be connected to the inner wall of the flue 20 in a sliding connection or other commonly used connection mode, as long as the baffle 32 can move and adjust between the closed state and the open state, which will not be exemplified one by one in the present application.
[0040] As shown in Figure 2 and Figure 3 some embodiments, the baffle 32 comprises a steam baffle 321 and a driving plate 322 fixed to each other, one of which is hinged to the inner wall of the flue 20, and in the closed state, the steam baffle 321 is in close contact with the exhaust pipe 31 to block the outlet of the exhaust pipe 31, and the driving plate 322 is located in the airflow path inside the flue 20 to block the airflow.
[0041] Preferably, in the closed state, the driving plate 322 is perpendicular to the airflow direction inside the flue 20.
[0042] As can be easily understood, when the driving plate 322 is perpendicular to the airflow direction inside the flue 20, the wind-blocking area of the driving plate 322 is the largest, and F1 is the largest.
[0043] Of course, the direction of the driving plate 322, the wind-blocking area and other parameters in the closed state can also be adaptively adjusted according to the fan power of the range hood, the weight of the baffle 32 and other factors, as long as F3 is greater than the resultant force of F2 and F1 in the closed state, and F3 is less than the resultant force of F2 and F1 in the open state.
[0044] As shown in Figure 2 and Figure 3 some embodiments, the flue 20 is provided with a hinge bracket 21 located above the exhaust pipe 31, and the steam baffle 321 is hinged to the hinge bracket 21.
[0045] In some embodiments, a torsional spring is further connected between the hinge bracket 21 and the steam baffle 321, and the torsional spring is used to drive the baffle 32 to restore to the closed state from the open state; by setting the torsional spring, the baffle 32 can be kept in the closed state in the steaming mode, and is always in close contact with the exhaust pipe 31 and will not be opened due to the slight pressure of the steam in the cooking liner 10.
[0046] For ease of description, the force of the torsional spring on the baffle 32 is defined as F4, then in the closed state, the resultant force of F3 and F4 is greater than the resultant force of F2 and F1; in the open state, the resultant force of F3 and F4 is less than the resultant force of F2 and F1.
[0047] As shown in Figure 2 and Figure 3 some embodiments, the hinge bracket 21 is provided with two hinge seats in the horizontal direction, and two hinge protrusions are correspondingly provided on the steam baffle 321, and each hinge protrusion is hinged to one hinge seat to improve the rotation stability of the baffle 32.
[0048] As shown in Figure 2 and Figure 3As shown, in some embodiments, in the closed state, the baffle 32 is attached to the steam exhaust pipe 31 to block at least part of the outlet area of the steam exhaust pipe 31, thereby reducing the steam exhaust volume while ensuring the exhaust of the waste steam inside the cooking liner 10, and increasing the use duration of the steaming function under the premise of unchanged water tank volume.
[0049] Please refer to Figure 2 and Figure 3 As shown, in some embodiments, in the closed state, the baffle 32 blocks half of the total outlet area of the steam exhaust pipe 31.
[0050] Of course, in other embodiments, the area of the steam exhaust pipe 31 blocked by the baffle 32 in the closed state can also be adjusted according to the actual steam exhaust requirement in the steaming mode, which is not limited in the present application.
[0051] The second aspect of the present application provides a multifunctional cooking device comprising the above-mentioned steam exhaust structure.
[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.
[0053] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, some modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
