[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0042] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] The present embodiment provides a cooking device, which may be a kitchen device with a function of steaming food, such as a steamer or a steam-bake-in-one machine.

[0044] like Figure 1 and Figure 2 As shown, the cooking device includes a machine body, a steam generating device 50 and a strong exhaust device 40. A cooking cavity is formed in the machine body, and the cooking cavity is provided with an air inlet 21 and an exhaust port. The steam generating device 50 is used to provide steam, and the steam generating device 50 includes a steam generator 51 and a steam pipeline 53. The steam generator 51 is connected to a water source (such as a water tank or a faucet) and a steam pipeline 53. The steam pipeline 53 is connected to the air inlet 21 so as to pass steam into the cooking cavity through the air inlet 21; the strong exhaust device 40 is connected to the outside of the machine body and the cooking cavity, and the strong exhaust device 40 is used to blow gas from the outside of the machine body into the cooking cavity so as to discharge the steam in the cooking cavity from the exhaust port.

[0045] After the steaming program is completed, the strong exhaust device 40 is started to transport the gas outside the machine body into the cooking cavity. On the one hand, the gas outside the machine body can lower the temperature in the cooking cavity, condense the moisture in the steam, and reduce the steam content in the cooking cavity. On the other hand, it can force the steam in the cooking cavity to be discharged out of the machine body through the exhaust port, thereby further reducing the steam in the cooking cavity and preventing the steam from spraying directly onto the user when the user opens the cooking cavity, thereby preventing the user from being scalded.

[0046] like Figure 1 As shown, an air inlet 101 and an air outlet 102 are provided on the machine body, the air inlet 101 is connected to the strong exhaust device 40, and the air outlet 102 is connected to the exhaust port on the cooking cavity. After the strong exhaust device 40 is started, the gas outside the machine body enters the cooking cavity through the air inlet 101, the strong exhaust device 40 and the air inlet 21 in turn; the gas in the cooking cavity is discharged to the outside of the machine body through the exhaust port and the air outlet 102 in turn.

[0047] In order to reduce the number of openings in the cooking cavity, the strong exhaust device 40 includes an air blast pipeline 42, one end of which can be connected to the outside of the machine body, and the other end of which can be connected to the steam pipeline 53. In this embodiment, the air blast pipeline 42 is connected to the steam pipeline 53, that is, the strong exhaust device 40 and the steam generating device 50 share part of the steam pipeline 53, so that the air inlet 21 on the cooking cavity has the function of passing steam and the function of passing the external gas of the machine body, and there is no need to open an additional hole in the cooking cavity to connect with the strong exhaust device 40, and the number of openings in the cooking cavity is reduced, which is conducive to improving the aesthetics, and at the same time, it can also improve the sealing performance and reduce the risk of gas leakage in the cooking cavity.

[0048] Combination Figure 1 and Figure 2 As shown, the machine body includes a housing 10 and an inner pot 20. The inner pot 20 is disposed in the housing 10, and the front end of the inner pot 20 is opened to form a take-in and put-out opening, and the inner pot 20 forms a cooking cavity, through which a user can take food in and put food in the cooking cavity.

[0049] like Figure 2 As shown, the steam pipeline 53 includes a steam inlet pipe 531 and a confluence pipe 532 that are connected to each other. The head end of the steam inlet pipe 531 is connected to the steam generator 51, and the end of the confluence pipe 532 is connected to the air inlet 21. The blast pipeline 42 is connected to one end of the confluence pipe 532 connected to the steam inlet pipe 531. In other words, the end of the blast pipeline 42, the end of the steam inlet pipe 531, and the head end of the confluence pipe 532 are connected, and the blast pipeline 42 and the steam inlet pipe 531 are both located above the confluence pipe 532.

[0050] When the steam generating device 50 is started, the strong exhaust device 40 is closed, and the steam generated by the steam generator 51 enters the cooking cavity through the steam inlet pipe 531, the confluence pipe 532 and the air inlet 21 in sequence; when the strong exhaust device 40 is started, the steam generating device 50 is closed, and the gas outside the machine body enters the blast pipe 42 through the air inlet 101, and then enters the cooking cavity through the confluence pipe 532 and the air inlet 21 to squeeze the steam in the cooking cavity, so that the steam is discharged from the outside of the machine body through the exhaust port and the air outlet 102.

[0051] Optionally, the blast pipe 42, the steam inlet pipe 531 and the confluence pipe 532 may be connected via a three-way pipe, which has a simple structure and low cost.

[0052] like Figure 3As shown, the gas in the air blast pipeline 42 enters the steam inlet pipe 531, and the air blast pipeline 42 includes a connecting section connected to the steam pipeline 53, and the angle between the connecting section and the steam inlet pipe 531 is an angle A, and the angle A is an acute angle. By setting the angle A to be an acute angle, the flow direction of the gas in the connecting section needs to be turned back before entering the steam inlet pipe 531, and the resistance is large, so that the gas in the connecting section can be prevented from entering the steam inlet section, which is conducive to ensuring the amount of external gas introduced into the cooking cavity, and can also prevent the steam generator 51 from being damaged due to the reverse flow of gas through the steam inlet pipe 531 into the steam generator 51.

[0053] Optionally, the angle A between the connecting section and the steam inlet pipe 531 may be no greater than 45°, so as to further prevent the gas in the blast pipeline 42 from entering the steam inlet pipe 531 .

[0054] In order to reduce the resistance of the gas in the connecting section when entering the confluence section, the angle between the connecting section and the confluence pipe 532 is not less than 90°. The angle between the connecting section and the confluence pipe 532 is relatively large, a right angle or an obtuse angle, so that the flow direction of the gas in the connecting section does not need to change significantly when entering the confluence section, thereby reducing the gas flow resistance and ensuring that the gas in the connecting section can smoothly enter the confluence pipe 532.

[0055] Preferably, the extension direction of the connecting section may be substantially the same as that of the confluence pipe 532 , or the extension direction of the connecting section may be the same as that of the head end of the confluence pipe 532 , so as to ensure that the gas in the connecting section can smoothly enter the confluence pipe 532 .

[0056] In order to reduce the resistance of the steam in the steam inlet pipe 531 when it enters the confluence section, the angle between the steam inlet pipe 531 and the confluence pipe 532 is not less than 90°. The angle between the steam inlet pipe 531 and the confluence pipe 532 is relatively large, a right angle or an obtuse angle, so that the flow direction of the steam in the steam inlet pipe 531 does not need to change significantly when it enters the confluence section, thereby reducing the gas flow resistance and ensuring that the steam in the steam inlet pipe 531 can smoothly enter the confluence pipe 532.

[0057] like Figure 3 As shown, the air inlet 21 is arranged at the bottom of the cooking cavity. Since the density of steam is relatively small, after the steam enters from the bottom of the cooking cavity, it can diffuse upward from the bottom of the cooking cavity and pass through the food from bottom to top, which is more conducive to food cooking.

[0058] The connecting section and the confluence pipe 532 extend roughly in the vertical direction. Specifically, one end of the confluence pipe 532 connected to the connecting section (i.e., the head end of the confluence pipe 532) extends vertically, and the other positions of the confluence pipe 532 can be bent to avoid surrounding structural parts. The steam inlet pipe 531 extends obliquely from top to bottom along the flow direction of the steam. Among them, the angle A between the steam inlet pipe 531 and the connecting section is an acute angle, and the angle B between the steam inlet pipe 531 and the confluence pipe 532 is an obtuse angle. The resistance of the steam in the steam inlet pipe 531 entering the confluence pipe 532 is small, which is conducive to the steam passing through the confluence pipe 532 smoothly into the cooking chamber.

[0059] In order to ensure the strong exhaust effect, the cross-sectional area S of the confluence pipe 532 satisfies: S=V / vT, where V is the volume of the cooking cavity, v is the airflow velocity of the strong exhaust device 40 blowing air into the cooking cavity, T is the maximum time for the strong exhaust device 40 to blow air into the cooking cavity, and T is a constant value set at the factory. The cross-sectional area of ​​the confluence pipe 532 satisfies the above formula, which can ensure that the steam in the cooking cavity can be completely discharged after the strong exhaust device 40 is started for T time to ensure the strong exhaust effect. It can be understood that the actual time for the cooking device to start the strong exhaust device 40 can be less than T, and the specific start time can be set by the user to better meet user needs.

[0060] Optionally, the maximum time T for the strong exhaust device 40 to blow air into the cooking cavity can be 1 min-3 min, preferably 1.5 min-2 min. Typical non-limiting values ​​of the maximum time T are listed as follows: 1.1 min, 1.2 min, 1.3 min, 1.4 min, 1.5 min, 1.6 min, 1.7 min, 1.8 min, 1.9 min, 2 min, 2.1 min, 2.2 min, 2.3 min, 2.4 min, 2.5 min, 2.6 min, 2.7 min, 2.8 min, 2.9 min or 3 min.

[0061] It is understandable that, when the structure of the machine body and the strong exhaust device 40 is determined, the volume V of the cooking cavity and the air flow rate v of the strong exhaust device 40 blowing air into the cooking cavity are both constant values. The volume V of the cooking cavity is determined by the size of the inner pot 20; Figure 2 As shown, the strong exhaust device 40 further includes a blower 41, which is connected to the air inlet 101 and the air blasting pipeline 42, and is used to drive the gas outside the machine body into the air blasting pipeline 42. When the model of the blower 41 is determined, the air flow velocity v of the strong exhaust device 40 blowing air into the cooking cavity is a determined constant value.

[0062] Optionally, the diameter of the confluence pipe 532 is not less than 12 mm. The confluence pipe 532 within this range can enable the gas in most current cooking chamber models to be completely discharged within about 2 minutes.

[0063] It is understandable that the cross-sectional area of ​​the interface of the air inlet 21 is substantially equal to that of the confluence pipe 532 to prevent the air inlet 21 from affecting the velocity of the incoming air flow.

[0064] In this embodiment, the housing 10 includes a housing and a door rotatably disposed on the front side of the housing. The bottom end of the door is rotatably connected to the housing 10, and the door can be flipped relative to the housing to open or close the access opening. Figure 1 As shown, the machine body further includes a control panel 30, which is disposed on the upper front side of the housing 10. The control panel 30 is used to interact with the user to control the operation and start and stop of the cooking device. In order to prevent the control panel 30 from interfering with the rotation of the door, there is an assembly gap between the control panel 30 and the housing 10, and the assembly gap forms an air inlet 101 and an air outlet 102 to avoid opening holes in the housing 10 and affecting the strength of the housing 10.

[0065] In addition, arranging the air inlet 101 and the air outlet 102 on the front side of the machine body can also ensure that when the cooking device is embedded in a kitchen cabinet, the air inlet 101 and the air outlet 102 are both located outside the cabinet, so that the gas introduced into the cooking cavity through the strong exhaust device 40 is the gas outside the cabinet, avoiding the gas in the closed cabinet from entering the cooking cavity, which is cleaner and more hygienic; in addition, the steam in the cooking cavity is discharged to the outside of the cabinet, avoiding entering the cabinet and causing the cabinet to become moldy or corroded.

[0066] Combination Figure 2 and Figure 3 As shown, the blower 41 in the strong exhaust device 40 is arranged above the inner tank 20, the steam generating device 50 is arranged at the rear side of the inner tank 20, and the air blowing pipeline 42 extends from the top of the inner tank 20 to the rear side so as to be connected with the steam pipeline 53.

[0067] The steam generating device 50 further includes a water vapor separation component 52, which is connected to the steam generator 51 and the steam inlet pipe 531. The steam provided by the steam generator 51 first enters the water vapor separation component 52 to separate the water carried in the steam; the separated steam enters the steam inlet pipe 531, and then enters the cooking cavity through the confluence pipe 532 and the air inlet 21, which is conducive to reducing the water content in the steam entering the cooking cavity, thereby ensuring the cooking effect.

[0068] It should be noted here that the water vapor separation component 52 is a common component in this field. The water vapor separation component 52 in this embodiment can adopt a water vapor separation component 52 with any structure and separation principle in the prior art. The structure and working principle of the water vapor separation component 52 are not specifically introduced in this embodiment.

[0069] In order to prevent steam from entering the blast pipe 42 and being discharged to the outside of the machine through the air inlet 101 when the steam generating device 50 is started, the strong exhaust device 40 also includes an on-off valve 43, which is arranged in the blast pipe 42 and is used to control the on-off of the blast pipe 42. When the cooking device needs to discharge steam, the steam generating device 50 stops working and no longer generates steam; the strong exhaust device 40 is started, the blower 41 works, and the on-off valve 43 is opened, so that the gas outside the machine body can smoothly enter the cooking cavity through the air inlet 101 and the blast pipe 42. When the cooking device needs to use steam for cooking, the strong exhaust device 40 is closed, the on-off valve 43 is closed, and the connection between the blast pipe 42 and the air inlet 101 is blocked; the steam generating device 50 is started, and the steam generated by the steam generator 51 enters the cooking cavity through the steam pipe 53, preventing the steam from being discharged through the blast pipe 42.

[0070] In this embodiment, the on-off valve 43 is arranged on the blast pipe 42 instead of the confluence pipe 532, and the steam inlet pipe 531 does not need to be provided with the on-off valve 43. On the one hand, this is to ensure that the steam generator 51 is always connected to the cooking chamber. After the steam generator 51 stops working, the residual heat of the steam generator 51 will continue to generate steam, and this part of the steam can enter the cooking chamber, avoiding the continued steam from staying in the steam pipe 53, causing the air pressure in the steam pipe 53 to continue to rise and cause an accident; on the other hand, since the steam generator 51 needs to be connected to a water source, the gas needs to pass through the steam generator 51 and the water source before it can be connected to the outside of the machine body, and the resistance is relatively large, which is conducive to the gas in the blast pipe 42 and the steam pipe 53 to enter the cooking chamber in a natural state.

[0071] The steam pipeline 53 includes an intersection point connected to the blast pipeline 42, which is the head end of the confluence pipe 532. The blast pipeline 42 includes an on-off control point cooperating with the on-off valve 43. The length of the blast pipeline 42 between the on-off control point and the intersection point is not more than 100 mm.

[0072] It is understandable that when the steam generator 51 is started and the on-off valve 43 is closed, the steam generated by the steam generator 51 will fill the steam pipeline 53 and the blast pipeline 42 between the on-off control point and the intersection point. This part of the steam is easy to condense in the pipeline, and the condensed water formed by the condensation will flow back to the bottom of the cooking cavity, resulting in excessive water in the cooking cavity. By shortening the length of the blast pipeline 42 between the on-off control point and the intersection point, it is helpful to reduce condensed water.

[0073] Since the on-off valve 43 needs to be set on the rear side of the inner tank 20, taking into account the installation space and the avoidance between structural parts, the length of the blower pipe 42 between the on-off control point and the intersection point should not exceed 100 mm on the basis of shortening the length of the blower pipe 42 between the on-off control point and the intersection point as much as possible.

[0074] In this embodiment, the on-off valve 43 can not only control the on-off of the air blast pipeline 42, but also adjust the effective flow area of ​​the air blast pipeline 42 to adjust the strong exhaust effect, thereby adjusting the humidity in the cooking cavity according to usage needs.

[0075] like Figure 4-Figure 6 As shown, the on-off valve 43 includes a fixed seat 431, a pusher 432 and a driving member 433. The fixed seat 431 is arranged on the body, and a clamping wall is arranged on the fixed seat 431; the pusher 432 is slidably arranged on the fixed seat 431 to approach or move away from the clamping wall, and the sliding direction of the pusher 432 is the arrangement direction of the pusher 432 and the clamping wall, that is, Figure 4 The X direction in the middle; the blast pipe 42 includes a hose section 421, which is located between the clamping wall and the pusher 432; the driving member 433 is arranged on the fixed seat 431 and connected to the pusher 432, and the driving member 433 is used to drive the pusher 432 to slide relative to the fixed seat 431. When the driving member 433 drives the pusher 432 to move toward the clamping wall, the pusher 432 abuts the hose section 421 against the clamping wall; as the moving distance of the pusher 432 increases, the hose section 421 is gradually flattened, and the effective flow area of ​​the hose section 421 becomes smaller, so that the air flow through the blast pipe 42 can be adjusted. When the driving member 433 drives the pusher 432 to move away from the clamping wall, the distance between the pusher 432 and the clamping wall gradually increases, and the hose section 421 can be restored to the open state under the action of the gas inside it, and the effective flow area of ​​the hose section 421 increases.

[0076] To make the push member 432 move more smoothly, a first sliding portion is provided on one of the fixed seat 431 and the push member 432, and a second sliding portion is provided on the other. The first sliding portion and the second sliding portion slide together to guide the sliding of the push member 432 to avoid jamming of the push member 432.

[0077] In this embodiment, the fixed seat 431 is provided with a first sliding portion, which is a guide rib 4313, and the guide rib 4313 extends along the X direction; the pusher 432 is provided with a second sliding portion, which is a guide groove provided on the bottom surface of the pusher 432, and the guide rib 4313 is located in the guide groove and can slide in the guide groove. In other embodiments, the guide rib 4313 can be provided on the pusher 432, and correspondingly, the guide groove is provided on the fixed seat 431, which can also realize the guiding function.

[0078] like Figure 5As shown, a avoidance groove is provided on the pusher 432, and the driving member 433 is provided on the fixing seat 431 and is located in the avoidance groove, and the avoidance groove extends along the sliding direction of the pusher 432. This arrangement, on the one hand, makes the structure of the on-off valve 43 more compact and reduces the size of the on-off valve 43; on the other hand, the cooperation between the avoidance groove and the driving member 433 can provide a guiding effect for the pusher 432 to avoid the pusher 432 from getting stuck due to the displacement in the moving direction.

[0079] like Figure 4 and Figure 5 As shown, a limiting groove 4322 is provided on the pusher 432, and the output end of the driving member 433 is provided in the limiting groove 4322 to fix the connection position of the driving member 433 and the pusher 432, so that the cooperation between the two is more stable. Optionally, the output end of the driving member 433 can be detachably provided in the limiting groove 4322, so as to facilitate the replacement of the pusher 432 or the driving member 433 separately as needed, thereby reducing maintenance costs.

[0080] In this embodiment, the push member 432 includes a bottom plate and a push vertical plate, the push vertical plate is substantially vertically connected to the push bottom plate, the push bottom plate contacts and slides with the fixed base, and the push vertical plate is arranged opposite to the clamping wall. Two clamping arms are arranged on the side of the push vertical plate away from the clamping wall, the free ends of the two clamping arms are arranged opposite to each other and spaced apart, and a limiting groove 4322 is formed between the two clamping arms and the push vertical plate. The output end of the driving member 433 passes through the gap between the two clamping arms and extends into the clamping groove, and an abutment portion is arranged on the output end of the driving member 433, and the size of the abutment portion is larger than the gap between the two clamping arms to prevent the output end of the driving member 433 from being separated from the limiting groove 4322.

[0081] In order to prevent the pusher 432 from moving in the up-down direction during the sliding process, thereby affecting the opening and closing effect of the hose section 421, a first clamping portion 4314 is provided on the fixed seat 431, and a second clamping portion 4323 is provided on the pusher 432. The first clamping portion 4314 is located above the second clamping portion 4323. When the pusher 432 slides along the fixed seat 431, the first clamping portion 4314 is above the second clamping portion 4323 to limit the pusher 432 from moving in the up-down direction.

[0082] In order to prevent the hose section 421 from detaching from the fixing seat 431 and affecting the function of the on-off valve 43, the fixing seat 431 is provided with a limiting portion, which cooperates with the blast pipe 42 and is used to confine the blast pipe 42 in the fixing seat 431 to prevent the hose section 421 from detaching from the fixing seat 431 upwards under the push of the pushing member 432.

[0083] In this embodiment, the fixing seat 431 includes a seat body, a clamping plate and two side plates, the clamping plate and the side plates are both arranged on the seat body, the clamping plate is located between the two side plates, a clamping wall is arranged on the clamping plate, the limiting portion is a limiting hole 4312 penetrating the side plate, and the air blast pipeline 42 is arranged in the limiting hole 4312. By providing the limiting hole 4312, the hose section 421 can be prevented from moving up and down, which is conducive to ensuring the clamping effect of the clamping wall and the pusher 432 on the hose section 421.

[0084] In some embodiments, the limiting portion may be disposed at the top end of the clamping plate, and the hose section 421 is located between the limiting portion and the seat body, so that the limiting portion limits the upward and downward movement of the hose section 421 .

[0085] In order to improve the blocking effect of the on-off valve 43 on the airflow in the hose section 421, a first protrusion 4321 is provided on the pusher 432, and a second protrusion 4311 is provided on the clamping wall, and the first protrusion 4321 and the second protrusion 4311 are staggered. When the pusher 432 cooperates with the clamping wall to clamp the hose section 421, the hose section 421 is bent under the action of the first protrusion 4321 and the second protrusion 4311, and the clamping effect is better, thereby improving the sealing effect on the hose section 421.

[0086] In this embodiment, two second protrusions 4311 are provided, and the two second protrusions 4311 are arranged at an interval to form a groove therebetween. The first protrusion 4321 can extend into the groove, which can provide a guide for the cooperation between the pushing member 432 and the clamping wall on the one hand, and can make the hose section 421 bend twice on the other hand, thereby achieving a better sealing effect on the hose section 421.

[0087] Optionally, the width of the groove gradually increases in the direction close to the pusher 432, and the shape of the first protrusion 4321 matches the shape of the groove, that is, the width of the opening end of the groove is large, and the width of the bottom end of the groove is small, which is conducive to the first protrusion 4321 extending into the groove.

[0088] In some embodiments, the number of the second protrusions 4311 may be greater than two, such as three, four or more.

[0089] In some embodiments, two first protrusions 4321 may be provided, and a groove may be formed between the two first protrusions 4321 . Correspondingly, the second protrusion 4311 may extend into the groove, and the blocking effect of the on-off valve 43 on the airflow in the hose section 421 may also be improved.

[0090] In order to ensure the closing and opening effect of the hose segment 421, the minimum movement distance between the pusher 432 and the clamping wall can be 0, so as to ensure that the pusher 432 can completely fit the inner wall of the hose segment 421 and block the flow of gas therein; the maximum movement distance between the pusher 432 and the clamping wall is not less than the outer diameter of the hose segment 421, so that the hose segment 421 can be fully opened under the action of the gas therein. For example, when the inner diameter of the hose segment 421 is 12 mm, the movement distance between the pusher 432 and the clamping wall is 0-20 mm.

[0091] Optionally, the driving member 433 may be a push rod motor, preferably a wax motor to reduce costs.
