- valve core 410 can enter or leave the valve channel 421 along the axial direction to close or open the valve channel 421 .
- the inner wall of the valve channel 421 is used to closely cooperate with the valve core 410 to close the valve channel 421 and the heat exchange port 300, and the drive assembly 430 is used to drive the valve core 410 to selectively move into and out of the valve channel 421 along the axial direction of the valve channel 421.

- a resistance portion 422 can be set at one end of the valve channel 421, and the valve can move axially to a position where it resists and separates from the resistance portion 422, thereby achieving the closure or opening of the valve channel 421.
- a resistance part 422 is provided at one end of the valve channel 421 away from the driving assembly 430, which is in resistance around the valve channel 421 and extends from the edge of the valve channel 421 to the center along the radial direction of the valve channel 421 to form an annular structure.
- the driving assembly 430 is used to drive the valve core 410 to selectively move along the axial direction of the valve channel 421 to resist and separate from the resistance part 422.

- valve core 410 opening and closing the valve channel 421 along the axial direction can be used alone, or a plurality of solutions can be used in combination, so as to further improve the reliability of the valve device 400.

- the advantage of the driving assembly 430 directly driving the valve core 410 is that it can simplify the structural complexity of the driving assembly 430 and improve the reliability of the driving assembly 430.
- a cylinder is selected to drive the valve core 410, and the piston rod of the cylinder is directly connected to the valve core 410.
- the advantage of the driving assembly 430 indirectly driving the valve core 410 to move through the transmission mechanism 432 is that, on the one hand, the number of valve cores 410 that can be driven by a single power source is more flexible, for example, it is convenient to drive multiple valve cores 410 to move at the same time. On the other hand, it is also convenient to optimize the spatial layout of the driving assembly 430, which is conducive to reducing the volume of the valve device 400.
- the driving component 430 when the driving component 430 is selected to indirectly drive the valve core 410 to move through the transmission mechanism 432, the driving component 430 includes a driving motor 431 and a transmission mechanism 432.

- the transmission mechanism 432 can be connected to the plurality of valve cores 410, so that the driving force of the driving motor 431 can be transmitted to the plurality of valve cores 410 through the transmission mechanism 432, thereby driving the plurality of valve cores 410 to move through one driving motor 431.
- the transmission direction of the driving force of the driving motor 431 can be changed through the transmission mechanism 432, so that the driving motor 431 can be arranged in a more suitable posture according to actual needs, thereby optimizing the spatial layout of the driving assembly 430.
- the driving motor 431 has an output shaft 4311 .
- the axis of the output shaft 4311 extends along the radial direction of the heat exchange port 300 .
- valve core 410 moves along the axial direction of the heat exchange port 300, a certain amount of movable space needs to be reserved in the axial direction of the heat exchange port 300. If the space occupied by the drive assembly 430 in the axial direction of the heat exchange port 300 is also large, the superposition of the two will cause the valve device 400 to occupy too much space in the axial direction of the heat exchange port 300, which is not conducive to the miniaturization of the valve device 400.
- the drive motor 431 when the drive motor 431 is placed along the radial direction of the heat exchange port 300, since the drive motor 431 is usually lower in the direction perpendicular to its output shaft 4311, the drive motor 431 occupies less space in the axial direction of the heat exchange port 300, which is conducive to the miniaturization of the valve device 400.

本实施例提供一种烹饪设备。
请参考图1-9，该烹饪设备包括主体部100、制冷装置200、换热口300和阀门装置400。
请参考图1-5，主体部100具有烹饪腔体110，制冷装置200包括换热腔体210和制冷元件220，制冷元件220设置在换热腔体210内换热口300位于主体部100与制冷装置200相邻的侧部，且换热口300将烹饪腔体110与换热腔体210连通。阀门装置400包括阀门芯410，阀门芯410能够至少部分地在换热口300内沿换热口300的轴向运动，以实现换热口300的开启和封闭。
当需要冷藏食品时，使阀门芯410至少部分地在换热口300内沿换热口300的轴向运动至将换热口300开启的位置，以使烹饪腔体110与换热腔体210连通，此时通过制冷元件220对换热腔体210的环境温度进行制冷，换热腔体210通过与烹饪腔体110空气对流以实现对烹饪腔体110的制冷。当烹饪腔体110加热食物时，使阀门芯410至少部分地在换热口300内沿换热口300的轴向运动至将换热口300封闭的位置，避免制冷装置200在烹饪腔体110的高温作用下损坏。从而实现了换热口300的灵活开关，在需要冷藏食品时可以保持换热口300的开启，以保证制冷效果，在需要加热食品时，可以保持换热口300的关闭，以避免损坏制冷装置200。
需要说明的是，换热口300的轴向指的是换热口300两端中心点连线的方向，换热口300的径向指的是垂直于换热口300的轴向的方向。同理，阀门通道421的轴向指的是阀门通道421两端中线点连线的方向，阀门通道421的径向指的是垂直于阀门通道421的轴向的方向。具体地，请参考图6，图6中轴线L1所示的方向为阀门通道421的轴向，图6中轴线L2所示的方向为阀门通道421的径向。可以理解的是，当阀门座420安装于换热口300时，换热口300的轴向可以与阀门通道421的轴向相同，换热口300的径向可以与阀门通道421的径向相同。
请参考图1-6，在一种实施例中，阀门装置400还包括阀门座420和驱动组件430，阀门座420连接于换热口300，阀门芯410与阀门座420活动连接，驱动组件430与阀门芯410连接，驱动组件430用于驱动阀门芯410沿换热口300的轴向运动，以实现换热口300的开启和封闭。
通过阀门座420实现阀门芯410在换热口300内的活动设置，通过驱动组件430为阀门芯410在换热口300内的运动提供动力。需要说明的是，本实施例中阀门芯410通过阀门座420间接地设置在换热口300 内。在其他实施例中，阀门芯410也可以直接与换热口300活动连接。本实施例中通过驱动组件430为阀门芯410的运动提供动力，在其他实施例中，阀门芯410的运动也可以是由使用者手动提供动力。
在实际应用场景中，阀门芯410可以是直接对换热口300进行封闭，也可以通过封闭阀门座420上阀门通道421的方式间接地实现对换热口300的封闭。
具体地，当选用间接封闭换热口300的方式时，请参考图1、4和5，在一种实施例中，阀门座420具有沿换热口300的轴向延伸的阀门通道421，阀门通道421的两端贯通，阀门通道421与换热口300密封连接，阀门芯410与阀门通道421活动连接，驱动组件430用于驱动阀门芯410沿阀门通道421的轴向运动，以实现阀门通道421和换热口300的开启和封闭。
当需要封闭换热口300时，通过驱动组件430驱动阀门芯410沿阀门通道421的轴向运动，以实现对阀门通道421的开启和封闭，从而间接实现对换热口300的开启和封闭。在其他实施例中，当阀门芯410直接与换热口300活动连接时，阀门芯410也可以是直接开启或封闭换热口300。
阀门芯410沿阀门通道421的轴向运动时，有多种可选的方式实现对阀门通道421的开启和封闭。
请参考图5，在第一种可选方式的实施例中，阀门通道421可以包括沿轴向设置的至少两段直径不同的部分，阀门芯410通过与阀门通道421的至少两段直径不同的部分配合，以实现对阀门通道421的开启和封闭。

当需要开启阀门通道421时，通过驱动组件430驱动阀门芯410沿轴向运动至开启段4211，开启段4211的内壁与阀门芯410之间形成供流体通过的间隙，从而实现阀门通道421的开启。当需要关闭阀门通道 421时，通过驱动组件430驱动阀门芯410沿轴向运动至封闭段4212，封闭段4212的内壁与阀门芯410紧密配合，从而实现对阀门通道421的封闭。
在第二种可选方式的实施例中，阀门芯410可以沿轴向进入或脱离阀门通道421，以实现对阀门通道421的封闭或开启。
具体地，在一种实施例中，阀门通道421的内壁用于与阀门芯410紧密配合，以封闭阀门通道421和换热口300，驱动组件430用于驱动阀门芯410沿阀门通道421的轴向可选择地运动至阀门通道421内和脱离阀门通道421。
当需要开启阀门通道421时，通过驱动组件430驱动阀门芯410沿轴向运动至脱离阀门通道421，从而实现阀门通道421的开启。当需要关闭阀门通道421时，通过驱动组件430驱动阀门芯410沿轴向运动至阀门通道421内，此时阀门通道421的内壁与阀门芯410紧密配合，从而实现阀门通道421的封闭。
请参考图8和9，在第三种可选方式的实施例中，可以在阀门通道421的一端设置抵触部422，阀门可以沿轴向运动至与抵触部422抵触和分离的位置，从而实现对阀门通道421的封闭或开启。
具体地，请参考图9，在一种实施例中，阀门通道421远离驱动组件430的一端设有抵触部422，抵触围绕阀门通道421的四周，并沿阀门通道421的径向从阀门通道421的边缘向中心延伸，以形成环状结构。驱动组件430用于驱动阀门芯410沿阀门通道421的轴向可选择地运动至与抵触部422抵触和分离。
当需要开启阀门通道421时，通过驱动组件430驱动阀门芯410沿轴向远离抵触部422运动，使阀门芯410与抵触部422分离，从而实现阀门通道421的开启。当需要关闭阀门通道421时，通过驱动组件430驱动阀门芯410沿轴向靠近抵触部422运动，使阀门芯410与抵触部422抵触，从而实现阀门通道421的封闭。
可以理解的是，上述三种阀门芯410沿轴向开启和封闭阀门通道421的方案可以单独使用，也可以将多种方案结合起来使用，从而进一步提升阀门装置400的可靠性。
需要说明的是，阀门装置400的驱动组件430可以是直接驱动阀门芯410运动，也可以是通过传动机构432间接驱动阀门芯410运动。驱 动组件430直接驱动阀门芯410的好处在于，能够简化驱动组件430的结构复杂度和提高驱动组件430的可靠性，例如，选用气缸驱动阀门芯410，气缸的活塞杆与阀门芯410直接连接。驱动组件430通过传动机构432间接驱动阀门芯410运动的好处在于，一方面，单个动力源能驱动的阀门芯410的数量更灵活，例如，便于同时驱动多个阀门芯410运动。另一方面，也便于优化驱动组件430的空间布局，从而有利于缩小阀门装置400的体积。
请参考图4和5，在一种实施例中，当选择驱动组件430通过传动机构432间接驱动阀门芯410运动的方案时，驱动组件430包括驱动电机431和传动机构432，传动机构432的一端与驱动电机431连接，另一端与阀门芯410连接，驱动电机431用于驱动传动机构432运动，以带动阀门芯410沿换热口300的轴向运动。
一方面，传动机构432可以与多个阀门芯410连接，以便于通过传动机构432将驱动电机431的驱动力传递给多个阀门芯410，从而实现通过一个驱动电机431驱动多个阀门芯410运动。另一方面，可以通过传动机构432改变驱动电机431的驱动力的传递方向，使得驱动电机431可以根据实际需求排布成更合适的姿态，从而实现对驱动组件430的空间布局的优化。
具体地，请参考图4和5，在一种实施例中，驱动电机431具有输出轴4311，输出轴4311的轴心线沿换热口300的径向延伸。
由于阀门芯410沿换热口300的轴向运动，因此需要在换热口300的轴向上预留一定的活动空间，如果驱动组件430在换热口300的轴向上占用的空间也较大，二者叠加会使得阀门装置400在换热口300轴向上占用的空间过大，不利于实现阀门装置400的小型化。而本实施例中，当驱动电机431沿换热口300的径向放置时，由于驱动电机431通常在垂直于其输出轴4311的方向上高度较低，使得驱动电机431在换热口300的轴向上占用的空间较小，从而有利于实现阀门装置400的小型化。
驱动组件430的传动机构432可以选用齿轮齿条结构、丝杆滑块结构或其他合适的传动结构。
请参考图4-6，在一种实施例中，当传动机构432选用齿轮齿条结构时，传动机构432包括驱动杆4321、驱动齿轮4322和驱动齿条4323，驱动杆4321沿阀门通道421的径向设置，驱动齿轮4322同轴套设于驱 动杆4321，驱动齿条4323沿阀门通道421的轴向设置，驱动齿条4323与驱动齿轮4322啮合，且驱动齿条4323与阀门芯410连接，驱动电机431用于驱动驱动杆4321转动，以带动驱动齿条4323和阀门芯410沿阀门通道421的轴向运动。
当需要驱动阀门芯410运动时，先通过驱动电机431驱动驱动杆4321转动，通过驱动杆4321带动驱动齿轮4322转动，通过驱动齿轮4322带动驱动齿条4323沿阀门通道421的轴向运动，进而通过驱动齿条4323带动阀门芯410沿阀门通道421的轴向运动。
在其他实施例中，也可以通过丝杆滑块结构或其他合适的传动结构替换齿轮齿条结构。例如，当选用丝杆滑块结构替换齿轮齿条结构时，可以在驱动电机431的输出轴4311上连接驱动丝杆，驱动丝杆沿阀门通道421的轴向设置，驱动丝杆上活动套设一个滑块，滑块沿阀门通道421的轴向延伸至与阀门芯410连接。当需要驱动阀门芯410运动时，通过电机驱动丝杆转动，进而带动滑块和阀门芯410沿阀门通道421的轴向运动。
请参考图4和7，在一种实施例中，驱动组件430还包括行程检测组件433，行程检测组件433包括行程检测齿轮4331、行程检测齿条4332和行程检测开关4333，行程检测齿轮4331同轴套设于驱动杆4321，行程检测齿条4332与驱动杆4321垂直，且与行程检测齿轮4331啮合，行程检测开关4333设置于行程检测齿条4332的延长线上，驱动电机431驱动驱动杆4321转动时，带动行程检测齿条4332沿行程检测齿条4332的延伸方向运动，以使行程检测齿条4332接触并触发行程检测开关4333。
当驱动电机431驱动阀门芯410运动时，驱动杆4321同时带动行程检测齿轮4331转动，行程检测齿轮4331带动行程检测齿条4332沿自身的延长线运动，当阀门运动至封闭或开启阀门通道421的位置时，行程检测齿条4332恰好运动至与行程检测开关4333接触，以触发行程检测开关4333，从而为驱动组件430的电控提供参考信号。
请参考图4和5，在一种实施例中，换热口300为多个，阀门装置400包括多个阀门通道421和多个阀门芯410，多个阀门通道421与多个换热口300一一对应地连接，多个阀门芯410一一对应地设置于多个阀门通道421内传动机构432与多个阀门芯410连接，驱动电机431驱动传动机构432运动时，传动机构432能够带动多个阀门芯410沿换热 口300的轴向运动。通过驱动电机431与传动机构432的配合，实现了同时驱动多个阀门芯410运动。
具体地，请参考图4和5，在一种实施例中，当传动机构432选用齿轮齿条结构时，传动机构432包括驱动杆4321、多个驱动齿轮4322和多个驱动齿条4323，驱动杆4321沿阀门通道421的径向设置，多个驱动齿轮4322均同轴套设于驱动杆4321，多个驱动齿条4323均沿阀门通道421的轴向设置，多个驱动齿条4323与多个阀门芯410一一对应地连接，且多个驱动齿条4323一一对应地与多个驱动齿轮4322啮合。
当需要驱动多个阀门芯410运动时，通过驱动电机431驱动驱动杆4321转动，带动驱动杆4321上的多个驱动齿轮4322转动，通过多个驱动齿轮4322带动多个驱动齿条4323沿阀门通道421的轴向运动，进而通过多个驱动齿条4323带动多个阀门芯410沿阀门通道421的轴向运动。
请参考图4和5，在一种实施例中，驱动组件430还包括多个支撑座434，驱动杆4321与支撑座434转动连接，驱动齿轮4322和驱动齿条4323位于支撑座434内。
一方面，通过支撑座434实现了对驱动杆4321的支撑，另一方面，支撑座434可以对内部的驱动齿轮4322和驱动齿条4323起到保护和限位的作用。
请参考图4和5，在一种实施例中，传动机构432还包括第一传动齿轮4324和第二传动齿轮4325，驱动电机431的输出轴4311与第一传动齿轮4324同轴连接，第二传动齿轮4325同轴套设于驱动杆4321，第一传动齿轮4324与第二传动齿轮4325啮合。
当需要驱动传动杆转动时，通过驱动电机431驱动第一传动齿轮4324转动，通过第一传动齿轮4324带动第二传动齿轮4325转动，进而通过第二传动齿轮4325带动传动轴转动。可以理解的是，当第一传动齿轮4324和第二传动齿轮4325的模数不同时，第一传动齿轮4324和第二传动齿轮4325还可以用于调节驱动电机431输出给驱动杆4321的转速。
另一方面，本实施例还提供一种阀门装置400，该阀门装置400可以应用于上述的烹饪设备。
请参考图1-7，该阀门装置400包括阀门座420、阀门芯410和驱动 组件430。
阀门座420具有两端贯通的阀门通道421，阀门芯410与阀门座420活动连接驱动组件430与阀门芯410连接，驱动组件430用于驱动阀门芯410至少部分地在阀门通道421内沿阀门通道421的轴向运动，以实现阀门通道421的开启和封闭。
可以理解的是，当阀门装置400应用于上述的烹饪设备，并安装于换热口300时，阀门通道421的轴向可以与换热口300的轴向相同，阀门通道421的径向可以与换热口300的径向相同。
以上应用了具体个例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本发明所属技术领域的技术人员，依据本发明的思想，还可以做出若干简单推演、变形或替换。
