[0002] Cooking equipment, such as steam ovens or stove-steam-bake machines, are becoming more and more popular among users because they have both steaming and baking functions. When the steam oven is in steaming mode, it is necessary to maintain a certain steam pressure and humidity in the cooking cavity; while when the steam oven is in baking mode, it is necessary to avoid excessive water vapor or high humidity in the cooking cavity, and the steam needs to be discharged in time to ensure good cooking results in different modes.

[0003] In addition, for the same steaming mode, different ingredients or different temperature requirements usually require different humidity. Existing steaming and baking cooking equipment cannot accurately control the humidity in the cooking cavity. Summary of the invention

[0004] In view of this, it is necessary to provide a cooking device to address the above problems so as to achieve accurate control of the humidity in the cooking cavity.

[0005] The present invention provides a cooking device, comprising: a box body, comprising a shell and an inner pot located in the shell, wherein the inner pot has a cooking cavity; a fan assembly, comprising a fan capable of forward and reverse rotation, wherein the fan is located between a rear wall of the shell and a rear wall of the inner pot; and an adjustment mechanism, which is arranged on the wall of the inner pot and comprises a humidity detection assembly and a humidity adjustment assembly, wherein the humidity detection assembly comprises a humidity sensor at least partially located in the cooking cavity, wherein the humidity adjustment assembly comprises an exhaust pump, an exhaust joint and a transmission member, wherein the transmission member is matched with the rotating shaft of the fan, wherein the exhaust pump can be connected to the cooking cavity in an openable and closable manner via the exhaust joint, and wherein the transmission member is used to drive the exhaust joint to open and close so as to control the connection state between the exhaust pump and the cooking cavity.

[0006] In the above cooking device, the humidity sensor can detect the humidity in the cooking cavity in real time. When the humidity in the cooking cavity needs to be increased, the exhaust joint can be driven to move to a closed state through the transmission member when the fan rotates forward or reversely, so that the vacuum pump is disconnected from the cooking cavity, and the water vapor in the cooking cavity cannot be discharged through the exhaust joint and the vacuum pump, so as to increase the humidity in the cooking cavity; when the humidity in the cooking cavity needs to be reduced, the exhaust joint can be driven to move to an open state through the transmission member when the fan rotates forward or reversely, so that the vacuum pump is connected to the cooking cavity through the exhaust joint. When the vacuum pump is working, the water vapor in the cooking cavity can be discharged through the exhaust joint and the vacuum pump, so as to reduce the humidity in the cooking cavity, thereby realizing precise control of the humidity in the cooking cavity.

[0007] In one embodiment, the exhaust joint includes a joint and an opening and closing member, the joint is arranged at the exhaust port of the exhaust pump, the joint is provided with first air holes arranged at intervals, the opening and closing member is provided with second air holes arranged at intervals, and the transmission member drives the opening and closing member to move so that the exhaust joint is in an open state or a closed state.

In the closed state, the first air hole and the second air hole are completely misaligned so that the exhaust pump is disconnected from the cooking cavity.

[0008] With such a configuration, negative pressure small-area dehumidification can be achieved through the vacuum pump and the exhaust joint, thereby ensuring the dehumidification efficiency while avoiding the rapid loss of temperature in the cooking cavity; and the relative area size of the first air hole and the second air hole can be adjusted by adjusting the position of the opening and closing part relative to the joint, thereby adjusting the dehumidification rate.

[0010] With such a configuration, when the gear section cooperates with the first gear, the fan can be controlled to rotate forward and reverse at a preset frequency, and the opening and closing member can be driven to rotate forward and reverse at a preset frequency through the first gear. The exhaust joint can switch between an open state and a closed state at a preset frequency to achieve intermittent dehumidification; when the transition section cooperates with the first gear, no matter how the fan rotates, the first gear will not drive the opening and closing member to rotate.

[0014] Such an arrangement enables the opening and closing part to be reliably connected to the joint, and the joint can limit the rotation axis of the rotating part to ensure the stability of the rotating part during rotation; the fit between the bottom of the joint and the bottom of the opening and closing part can prevent water vapor leakage in the cooking cavity.

[0018] With such an arrangement, the humidity sensor can detect the humidity at different heights in the cooking cavity, so as to realize dynamic real-time monitoring of the humidity in the cooking cavity and improve the accuracy of the humidity detection result.

[0019] In one embodiment, the transmission member is a first gear, the lifting member is a first rack meshing with the first gear, and the first rack is arranged along the height direction of the inner container.

[0021] In one embodiment, the humidity detection assembly further includes a first guide frame, the first guide frame is provided with a second avoidance hole corresponding to the first avoidance hole, and the first guide frame is sealingly connected to an edge of the first avoidance hole.

[0022] In this arrangement, the first guide frame is used to support the lifting member and limit the lifting range of the lifting member, while preventing the heat, steam or smoke in the cooking cavity from being lost, ensuring the cooking effect, and preventing steam or smoke leakage from causing damage to other components outside the inner pot.

[0023] In one of the embodiments, it also includes a temperature detection component arranged on the inner pot, the temperature detection component includes a temperature detector and a transmission group, the temperature detector is arranged on the transmission group and is at least partially located in the cooking cavity, and the transmission member drives the transmission group so that the temperature detector is movable along the length direction of the inner pot.

[0024] With such an arrangement, the temperature at different positions in the cooking cavity can be detected by the temperature detector, so as to realize dynamic and real-time temperature monitoring of the cooking cavity and improve the accuracy of the temperature detection result.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0039] Cooking equipment, such as steam ovens or stove-steam-and-bake all-in-one machines, are becoming more and more popular among users because they have both steaming and baking functions. When the steam oven is in steaming mode, it is necessary to maintain a certain steam pressure and humidity in the cooking cavity; while when the steam oven is in baking mode, it is necessary to avoid excessive water vapor or high humidity in the cooking cavity, and it is necessary to discharge the steam in time to ensure good cooking effects in different modes. In addition, for the same steaming mode, different ingredients or different temperature requirements usually require different humidity, and existing steam-and-bake cooking equipment cannot accurately control the humidity in the cooking cavity.

[0040] In order to solve the above problems, Figures 1 to 6 As shown, the present invention provides a cooking appliance, which can achieve accurate control of the humidity in the cooking cavity. The cooking appliance can be a steam oven or the like.

[0041] like Figure 1 to Figure 2 As shown, specifically, the cooking device includes a box body 10, a fan assembly 20 and an adjustment mechanism 30, wherein: the box body 10 includes a shell and an inner pot 11 located in the shell, and the inner pot 11 has a cooking cavity 111; the fan assembly 20 includes a fan 21 that can rotate forward and reverse, and the fan 21 is located between the rear wall of the shell and the rear wall of the inner pot 11; the adjustment mechanism 30 is arranged on the wall of the inner pot 11, and includes a humidity detection assembly 31 and a humidity adjustment assembly 32, the humidity detection assembly 31 includes a humidity sensor 311 at least partially located in the cooking cavity 111, the humidity adjustment assembly 32 includes an exhaust pump 321, an exhaust joint 322 and a transmission member 323, the transmission member 323 is matched with the rotating shaft of the fan 21, the exhaust pump 321 can be opened and closed to connect to the cooking cavity 111 through the exhaust joint 322, and the transmission member 323 is used to drive the exhaust joint 322 to open and close to control the connection state between the exhaust pump 321 and the cooking cavity 111.

[0042] In the cooking device provided by the embodiment of the present invention, during the cooking process, the forward and reverse rotation of the fan 21 can drive the air flow in the cooking cavity 111, so that the temperature and humidity in the cooking cavity 111 are uniform, and the humidity sensor 311 can detect the humidity in the cooking cavity 111 in real time; when the humidity in the cooking cavity 111 needs to be increased, the exhaust joint 322 can be driven to move to a closed state through the transmission member 323 when the fan 21 rotates forward or reversely, so that the exhaust pump 321 is disconnected from the cooking cavity 111, and the water vapor in the cooking cavity 111 cannot pass through the exhaust joint 32 2 and the exhaust pump 321 to increase the humidity in the cooking cavity 111; when the humidity in the cooking cavity 111 needs to be reduced, the exhaust joint 322 can be driven to move to the open state through the transmission member 323 when the fan 21 is reversed or forward, so that the exhaust pump 321 is connected to the cooking cavity 111 through the exhaust joint 322. When the exhaust pump 321 is working, the water vapor in the cooking cavity 111 can be discharged through the exhaust joint 322 and the exhaust pump 321 to reduce the humidity in the cooking cavity 111, thereby realizing accurate control of the humidity in the cooking cavity 111.

[0043] like Figure 1 to Figure 2 As shown, in one embodiment, the cooking device further includes an exhaust pipe 40, one end of which is connected to the cooking cavity 111, and the other end is connected to the outside; the exhaust end of the vacuum pump 321 is connected to the exhaust pipe 40. When the exhaust joint 322 is in an open state, the water vapor in the cooking cavity 111 can be quickly discharged through the exhaust pipe 40 and the vacuum pump 321 at the same time to improve the dehumidification efficiency; when the exhaust joint 322 is in a closed state, the water vapor in the cooking cavity 111 is only slowly discharged through the exhaust pipe 40 to avoid danger caused by excessive air pressure in the cooking cavity 111. In addition, the water vapor discharged from the vacuum pump 321 can be collected in the exhaust pipe 40 and discharged together, avoiding the need to open an additional exhaust port on the housing.

[0044] Of course, in other embodiments, the vacuum pump 321 may be provided separately from the exhaust pipe 40 ; or, the exhaust pipe 40 may not be provided, and the water vapor in the cooking cavity 111 is only discharged through the exhaust joint 322 and the vacuum pump 321 .

[0045] like Figure 3 and Figure 6As shown, the exhaust joint 322 includes a joint 3221 and an opening and closing member 3222. The joint 3221 is arranged at the exhaust port of the exhaust pump 321. The joint 3221 is provided with first air holes 3223 arranged at intervals, and the opening and closing member 3222 is provided with second air holes 3224 arranged at intervals. The transmission member 323 drives the opening and closing member 3222 to move so that the exhaust joint 322 is in an open state or a closed state. In the open state, the first air hole 3223 and the second air hole 3224 are at least partially opposite to each other so that the exhaust pump 321 is connected to the cooking cavity 111. In the closed state, the first air hole 3223 and the second air hole 3224 are completely misaligned so that the exhaust pump 321 and the cooking cavity 111 are in a disconnected state. When exhaust is required through the exhaust connector 322 and the air pump 321, the transmission member 323 can drive the opening and closing member 3222 to move to a position where the second air hole 3224 is at least partially opposite to the first air hole 3223 on the connector 3221, so that the water vapor in the cooking cavity 111 can be discharged through the second air hole 3224, the first air hole 3223 and the air pump 321 in sequence. When exhaust is not required through the exhaust connector 322 and the air pump 321, the transmission member 323 can drive the opening and closing member 3222 to move to a position where the second air hole 3224 is completely misaligned with the first air hole 3223 on the connector 3221, so that the water vapor in the cooking cavity 111 cannot enter the air pump 321 through the first air hole 3223. Since the apertures of the first air hole 3223 and the second air hole 3224 are small, negative pressure small-area dehumidification can be achieved through the air pump 321 and the exhaust connector 322, so that the temperature in the cooking cavity 111 can be prevented from losing quickly while ensuring the dehumidification efficiency.

[0046] It should be noted that the first pore 3223 and the second pore 3224 are at least partially relative to each other, which means that the projection of the second pore 3224 on the joint 3221 at least partially overlaps with the first pore 3223; the first pore 3223 and the second pore 3224 are completely misaligned, which means that the projection of the second pore 3224 on the joint 3221 does not overlap with the first pore 3223. It can be understood that the larger the relative area of ​​the first pore 3223 and the second pore 3224 is, the faster the moisture removal rate is. Therefore, the relative area of ​​the first pore 3223 and the second pore 3224 can be adjusted by adjusting the position of the opening and closing member 3222 relative to the joint 3221, thereby adjusting the moisture removal rate.

[0047] like Figures 4 to 5As shown, in one embodiment, the transmission member 323 is a first gear, the opening and closing member 3222 includes a rotating part 3225 and an opening and closing member 3226 having a second air hole 3224, the opening and closing member 3226 is arranged on the rotating part 3225, and the rotating part 3225 includes a gear segment 3227 that can mesh with the first gear and a transition segment 3228 that can be separated from the first gear. The rotating shaft of the fan 21 can drive the first gear to rotate synchronously, when the gear segment 3227 of the rotating part 3225 meshes with the first gear, the first gear can drive the rotating part 3225 to rotate, and the rotating part 3225 can drive the opening and closing member 3226 to rotate relative to the joint 3221 to adjust the relative area size of the first air hole 3223 and the second air hole 3224. The movement mode of the opening and closing member 3226 is simple, and the transmission matching structure of the transmission member 323 and the rotating part 3225 is simple, so as to control the position of the opening and closing member 3222 relative to the joint 3221 and improve the adjustment accuracy.

[0048] Specifically, the gear section 3227 is arc-shaped; the transition section 3228 can be arc-shaped or notched, as long as it is ensured that the first gear will not drive the rotating part 3225 to rotate when the transition section 3228 cooperates with the first gear. When the rotating part 3225 rotates to the position where the gear section 3227 cooperates with the first gear, the gear section 3227 meshes with the first gear. At this time, the fan 21 can be controlled to rotate forward and reverse at a preset frequency, so that the gear section 3227 is always meshed with the first gear, so as to drive the rotating part 3225 and the opening and closing part 3226 to rotate forward and reverse at a preset frequency through the first gear, and the exhaust joint 322 can switch between the open state and the closed state at a preset frequency, so as to achieve intermittent moisture removal, and further avoid the rapid loss of temperature in the cooking cavity 111. When the rotating part 3225 rotates to the position where the transition section 3228 cooperates with the first gear, the gear section 3227 and the transition section 3228 are disengaged from the first gear. At this time, no matter how the fan 21 rotates, the first gear will not drive the rotating part 3225 and the opening and closing part 3226 to rotate.

[0049] Of course, in other embodiments, the transmission member 323 and the rotating part 3225 can also cooperate with each other through other transmission methods such as worm gears, synchronous pulleys, etc. Alternatively, the opening and closing member 3222 can also be slidably arranged on the joint 3221 to adjust the relative area size of the first air hole 3223 and the second air hole 3224. The transmission member 323 can be a first gear, and the opening and closing member 3222 includes a rack segment that can mesh with the first gear and a transition segment 3228 that can be disengaged from the first gear.

[0050] like Figure 6As shown, in one embodiment, the first air holes 3223 are multiple groups, the same group of first air holes 3223 are arranged at intervals along the radial direction of the opening and closing part 3226, and multiple groups of first air holes 3223 are arranged at intervals along the circumference of the opening and closing part 3226; similarly, the second air holes 3224 are multiple groups, the same group of second air holes 3224 are arranged at intervals along the radial direction of the joint 3221, and multiple groups of second air holes 3224 are arranged at intervals along the circumference of the joint 3221. The first air holes 3223 can be arranged in a one-to-one correspondence with the second air holes 3224. When the relative area of ​​the first air holes 3223 and the second air holes 3224 is the largest, all the first air holes 3223 are opposite to the corresponding second air holes 3224, and the exhaust joint 3221 is in a fully open state. Alternatively, when the relative area of ​​the first air holes 3223 and the second air holes 3224 is the largest, most of the first air holes 3223 can be opposite to the corresponding second air holes 3224.

[0051] Of course, in other embodiments, the first air hole 3223 can also be an arc-shaped hole coaxial with the rotation axis of the opening and closing part 3226, and the second air hole 3224 is an arc-shaped hole corresponding to the first air hole 3223. When the first air hole 3223 and the second air hole 3224 completely overlap, the exhaust connector 3221 is in a fully open state, and the overlapping area of ​​the first air hole 3223 and the second air hole 3224 can be adjusted by adjusting the rotation angle of the opening and closing part 3226 relative to the connector 3221.

[0052] like Figure 6 As shown, the opening and closing part 3226 is in a cylindrical shape, the joint 3221 is in a cylindrical shape, the opening and closing part 3226 is sleeved on the joint 3221, the bottom of the opening and closing part 3226 is provided with a second air hole 3224, the opening and closing part 3226 is connected to the cooking cavity 111, the bottom of the joint 3221 is provided with a first air hole 3223, and the bottom of the joint 3221 is fitted with the bottom of the opening and closing part 3226. The opening and closing part 3226 is sleeved on the joint 3221 so that the two are reliably connected, and the joint 3221 can limit the rotation axis of the rotating part 3225 to ensure the stability of the rotating part 3225 when rotating. The bottom of the joint 3221 is fitted with the bottom of the opening and closing part 3226 to ensure the sealing between the joint 3221 and the opening and closing part 3226, so as to prevent the water vapor in the cooking cavity 111 from leaking through the gap between the bottom of the joint 3221 and the bottom of the opening and closing part 3226.

[0053] like Figures 4 to 5As shown, the adjustment mechanism 30 further includes an auxiliary component 33, which includes a driving motor 331 and a latching tooth 332 disposed on the output shaft of the driving motor 331, and the latching tooth 332 can mesh with the gear segment 3227; the latching tooth 332 and the first gear are respectively located on both sides of the rotation axis of the rotating portion 3225. At any angle of the rotating portion 3225, the gear segment 3227 can mesh with at least one of the first gear and the latching tooth 332. When the transition segment 3228 is mated with the first gear, the gear segment 3227 is mated with the latching tooth 332. When the driving motor 331 is controlled to drive the latching tooth 332 to rotate, the latching tooth 332 can mesh with the gear segment 3227 and drive the rotating portion 3225 to rotate to a position where the gear segment 3227 is meshed with the first gear. When the gear segment 3227 cooperates with the first gear, the gear segment 3227 may cooperate with the latching tooth 332. At this time, the driving motor 331 is controlled to drive the latching tooth 332 to rotate to a position disengaged from the gear segment 3227, so as to prevent the latching tooth 332 from affecting the normal rotation of the rotating part 3225. Alternatively, when the gear segment 3227 cooperates with the first gear, the transition segment 3228 may cooperate with the latching tooth 332. At this time, the latching tooth 332 will not affect the normal rotation of the rotating part 3225, and the rotating part 3225 can be driven to rotate to a position where the gear segment 3227 cooperates with the latching tooth 332 through the first gear. In this way, when the exhaust joint 322 needs to be adjusted, the auxiliary component 33 can be used to control the rotating part 3225 to rotate to the position where the gear section 3227 cooperates with the first gear, so that the first gear can drive the opening and closing part 3222 to rotate synchronously when it rotates; when the exhaust joint 322 does not need to be adjusted, the auxiliary component 33 can be used to control the rotating part 3225 to rotate to the position where the transition section 3228 cooperates with the first gear, so that the first gear will not drive the opening and closing part 3222 to rotate when it rotates.

[0054] like Figure 1 to Figure 2 As shown, the humidity detection assembly 31 also includes a lifting member 312, and the humidity sensor 311 is arranged on the lifting member 312. The transmission member 323 cooperates with the lifting member 312 to drive the humidity sensor 311 to rise and fall along the height direction of the inner pot 11; the inner pot 11 is provided with a first avoidance hole 112 that allows the humidity sensor 311 to rise and fall. When the fan 21 rotates forward and reverse at a preset frequency, the transmission member 323 can drive the lifting member 312 to rise and fall back and forth along the height direction of the inner pot 11 at a preset frequency, so that the humidity sensor 311 can rise and fall back and forth in the cooking cavity 111 at a preset frequency, so that the humidity sensor 311 can rise and fall back and forth in the cooking cavity 111 at a preset frequency, so that the humidity at different heights in the cooking cavity 111 can be detected by the humidity sensor 311, so as to realize dynamic real-time monitoring of the humidity of the cooking cavity 111 and improve the accuracy of the humidity detection result.

[0055] like Figures 1 to 3As shown, when the transmission member 323 is a first gear, the lifting member 312 is a first rack meshing with the first gear, and the first rack is arranged along the height direction of the inner container 11. The matching mode of the first gear and the first rack is simple, easy to assemble, and low in cost.

The second guide frame 523 is used to support the second rack 522 and limit the sliding range of the second rack 522, so as to ensure that the second rack 522 always slides along the length direction of the inner pot 11. The second rack 522 and the second guide frame 523 are covered on the third avoidance hole 113, and the sealing connection between the second guide frame 523 and the edge of the third avoidance hole 113 can prevent the heat, steam or smoke in the cooking cavity 111 from being lost through the third avoidance hole 113 and the gap between the second guide frame 523 and the edge of the third avoidance hole 113, thereby ensuring the cooking effect, and also preventing the steam or smoke leakage from causing damage to other components outside the inner pot 11.

[0060] like Figures 1 to 3 As shown, since the cooking device is usually provided with heating elements at the top and bottom of the cooking cavity 111, respectively. Therefore, there are two groups of temperature detection components 50, and the temperature detectors 51 of the two groups of temperature detection components 50 are at least partially located at the top and bottom of the cooking cavity 111, respectively. The two groups of temperature detection components 50 can monitor the temperature of the areas near the top and bottom of the cooking cavity 111 in real time, and can control the power of the two heating elements according to the detection results of the two groups of temperature detection components 50, so as to achieve accurate control of the temperature in the cooking cavity 111. In addition, arranging the two temperature detection components 50 at the top and bottom of the cooking cavity 111, respectively, can also avoid interference with the baking tray, grill or food in the cooking cavity 111.
