其全部内容通过引用结合在本申请中。The entire content is incorporated into this application by reference.
技术领域Technical field
本发明涉及食品加工领域，尤其涉及一种方便加工的空气炸锅。The invention relates to the field of food processing, in particular to an air fryer that is convenient for processing.
背景技术Background technique
现有的空气炸锅，特别是一种包括搅拌装置的空气炸锅，通常包括盖体和机座，盖体设有热风风扇和加热件，机座设有容纳腔，容纳腔内设有内锅，搅拌装置设置于内锅内。该空气炸锅依靠热风风扇和加热件对放置于内锅内的食材进行加热烧烤，以完成对食材的加工。而设置搅拌装置，可进一步的对内锅内的食材进行搅拌翻转，特别是对于较小的、分散的食材，当食材堆积时不易加工均匀，设置搅拌装置可解决该问题。The existing air fryer, especially an air fryer including a stirring device, usually includes a cover body and a base. The cover body is provided with a hot air fan and a heating element. The base is provided with a containing cavity, and the containing cavity is provided with an internal The pot and the stirring device are arranged in the inner pot. The air fryer relies on a hot air fan and a heating element to heat and grill the food materials placed in the inner pot to complete the processing of the food materials. The stirring device is provided to further stir and turn the ingredients in the inner pot, especially for small and dispersed ingredients, which are not easy to be processed uniformly when the ingredients are piled up. The stirring device can solve this problem.
但这种空气炸锅相对加工功能单一，只能用于烧烤食材，并且持续烧烤食材，还会使得食材过于干燥，在加工肉类时，会使得肉类食材失水过多，而影响肉类食材的口感。However, this kind of air fryer has relatively single processing function and can only be used for grilling ingredients, and continuous grilling of ingredients will also make the ingredients too dry. When processing meat, it will cause the meat ingredients to lose too much water and affect the meat. The taste of the ingredients.
对于上述问题，申请号CN201720587695.7公开了一种空气炸锅，其在内锅内设置储水装置，在储水装置内注水，工作过程中，储水装置内的水会被加热而形成蒸汽，蒸汽进入容纳腔内，使得容纳腔内的温度增加，进 而改善食物的口感。In response to the above problems, the application number CN201720587695.7 discloses an air fryer, which is equipped with a water storage device in the inner pot, and water is injected into the water storage device. During the working process, the water in the water storage device will be heated to form steam , The steam enters the containing cavity, which increases the temperature in the containing cavity, thereby improving the taste of the food.
但这种空气炸锅直接将储水装置设置于容纳腔内，在工作过程中，如果储水装置内有水，则能实现增加蒸汽的功能，储水装置内无水或者水被蒸发完，则无法再实现加温容纳腔的目的，并且，储水装置设置于容纳腔内，若设定的程序不需要蒸汽加温，但如果用户在储水装置内注水，则加工过程中无法控制蒸汽的产生，反而使得食材不能被更好的加工。而储水装置仅依靠空气炸锅本身的加热件来实现加热，随着容纳腔内的温度升高，蒸汽产生的速度增加，但蒸汽的速度无法控制，对于需要快速产生蒸汽的功能，无法满足；而由于储水装置会吸收部分加热件产生的热量，也使得空气炸锅整体加工效率降低。However, this air fryer directly installs the water storage device in the containing cavity. During the working process, if there is water in the water storage device, the function of increasing steam can be realized. There is no water in the water storage device or the water is evaporated. The purpose of heating the accommodating cavity can no longer be achieved, and the water storage device is arranged in the accommodating cavity. If the set program does not require steam heating, but if the user injects water into the water storage device, the steam cannot be controlled during processing The production of food, on the contrary, makes the food materials unable to be better processed. The water storage device only relies on the heating element of the air fryer itself to achieve heating. As the temperature in the accommodating cavity rises, the steam generation speed increases, but the steam speed cannot be controlled, which cannot meet the needs of fast steam generation functions. ; And because the water storage device will absorb the heat generated by some heating elements, the overall processing efficiency of the air fryer is also reduced.
使用者在使用空气炸锅时期望加工过程中能同时观察到容纳腔内部的食材，这时，需要在盖体上设置观察窗，但由于热风组件占据了盖体的较大比例体积，观察窗无法设置较大的面积，使用者从观察窗观察时，不能完全的观察到食材，影响对食材加工过程中的控制。现有还有一种是将热风组件及观察窗抬高，从竖向空间上扩大观察窗的面积，以实现完全观察的功能，但这样造成盖体及整机高度增加，重心上移，整机工作稳定性降低，当盖体打开时会存在倾倒的风险，并且增加了体积，容纳腔上方不能用于加工的空间增大，造成空间及能量有浪费，还使用整机不方便存储。When using the air fryer, the user expects to observe the food inside the cavity at the same time during the processing. At this time, it is necessary to install an observation window on the cover, but because the hot air component occupies a larger proportion of the volume of the cover, the observation window It is impossible to set a large area, and when the user observes from the observation window, the food material cannot be completely observed, which affects the control of the food material processing process. Another existing method is to raise the hot air component and the observation window to enlarge the area of the observation window from the vertical space to realize the complete observation function. However, this causes the height of the cover and the whole machine to increase, and the center of gravity moves up. The working stability is reduced, there is a risk of tipping when the cover is opened, and the volume is increased. The space above the accommodating cavity that cannot be used for processing increases, resulting in waste of space and energy, and inconvenient storage when using the whole machine.
综上而言，现有技术结构复杂，功能单一，仅仅是部分解决现有问题存在的缺陷，例如当用户需要大量蒸汽来实现纯蒸的功能时，无法满足需求。In summary, the existing technology has a complex structure and a single function, which only partially solves the defects of the existing problems. For example, when a user needs a large amount of steam to achieve the function of pure steam, the demand cannot be met.

2.设置搅拌装置，来满足工作过程中对食材搅拌的需求。进一步将驱动搅拌装置的驱动轴设置为中空，蒸汽发生器与驱动轴连通并通过中空的驱动轴将蒸汽通入内锅内，依靠现有产品中现有结构，只需要将驱动轴替换为中空的驱动轴，即可满足注入蒸汽的功能，对于产品的改变很小，需要替换的配件较小，产品升级方便。蒸汽依靠驱动轴进行传输，可同时实现蒸汽及动力传输，满足空气炸锅多功能的需求，并且，只需设置共同的传输路径即可实现蒸汽和动力传输，结构要求简单。蒸汽依靠驱动轴进行传输，依靠现有的密封结构，即可同时满足驱动结构和蒸汽传输的要求，技术要求简单，而由于驱动轴本身的密封结构技术成熟，因此，对于整机的密封，特别是蒸汽传输的密封要求大大降低，蒸汽传输的可靠性得到保证；蒸汽在驱动轴内传输，能更好的防止蒸汽进入驱动***，特别是驱动电机，从而更好的解决了蒸汽泄漏的问题。2. Set up a stirring device to meet the demand for stirring food during the work process. Further set the drive shaft for driving the stirring device to be hollow, the steam generator communicates with the drive shaft and the steam is passed into the inner pot through the hollow drive shaft. Relying on the existing structure in the existing product, it is only necessary to replace the drive shaft with a hollow The drive shaft can satisfy the function of injecting steam, the product changes are small, the parts to be replaced are small, and the product upgrade is convenient. The steam is transmitted by the drive shaft, which can realize the transmission of steam and power at the same time, meeting the multi-function requirements of the air fryer, and only need to set a common transmission path to realize the transmission of steam and power, with simple structural requirements. The steam depends on the drive shaft for transmission. Relying on the existing sealing structure, it can meet the requirements of the drive structure and steam transmission at the same time. The technical requirements are simple. Since the sealing structure technology of the drive shaft itself is mature, it is particularly important for the sealing of the whole machine. The sealing requirements of steam transmission are greatly reduced, and the reliability of steam transmission is guaranteed; steam transmission in the drive shaft can better prevent steam from entering the drive system, especially the drive motor, so as to better solve the problem of steam leakage.
3.由于搅拌装置通常设置于内锅底部，以对内锅内的食材进行搅拌，将驱动轴设置于内锅底部中心，这样，驱动源及驱动轴设置于机座，对于驱动轴的传输路径要求最短，位于驱动轴内的蒸汽传输路径也比较短，方便蒸汽的快速传输，密封可靠性也能保证。将驱动轴设置于内锅底部中心，蒸汽出口通常也设置于内锅底部中心，这样蒸汽从内锅底部进入内锅内，而蒸汽本身向上升，顺应了蒸汽本身的特性，能提升蒸汽的加工效率，设置于内锅中心，搅拌和蒸汽在整体内锅风均匀设置，不会存在死角，加工均匀。驱动轴设置为驱动段和连接段，驱动段与机座连接设置，连接段设置于内锅上，这样连接段可随内锅一起拆装，在连接段与内锅之间设置密 封结构，即可保证驱动轴与内锅之间的密封，防止蒸汽由驱动轴与内锅之间的连接处进入机座内。并且，连接段设置于内锅上，当空气炸锅加工完成后，连接段及搅拌装置可随内锅一起拆卸拿起，而无需将驱动轴和搅拌装置再拆卸，方便用户操作使用。3. Since the stirring device is usually set at the bottom of the inner pot to stir the ingredients in the inner pot, the drive shaft is set at the center of the bottom of the inner pot. In this way, the drive source and the drive shaft are set on the base, which is very important for the transmission path of the drive shaft. The requirement is the shortest, and the steam transmission path located in the drive shaft is also relatively short, which facilitates the rapid transmission of steam and guarantees the reliability of the seal. Set the drive shaft at the center of the bottom of the inner pot, and the steam outlet is usually set at the center of the bottom of the inner pot, so that the steam enters the inner pot from the bottom of the inner pot, and the steam itself rises, conforming to the characteristics of the steam itself, and can improve the steam processing Efficiency, set in the center of the inner pot, stirring and steam are evenly set in the whole inner pot wind, there will be no dead corners, and the processing is even. The drive shaft is set as a drive section and a connecting section. The drive section is connected to the machine base. The connecting section is set on the inner pot so that the connecting section can be disassembled and assembled together with the inner pot. A sealing structure is provided between the connecting section and the inner pot. It can ensure the seal between the drive shaft and the inner pot and prevent steam from entering the machine base from the connection between the drive shaft and the inner pot. In addition, the connecting section is arranged on the inner pot. After the air fryer is processed, the connecting section and the stirring device can be disassembled and picked up along with the inner pot without disassembling the drive shaft and the stirring device, which is convenient for users to operate and use.
4.驱动轴设置单向阀和触发部，这样，仅在驱动段和连接段安装到位后，蒸汽输送管路才导通并实现蒸汽传输，未安装连接段时，单向阀未触发，不会有蒸汽传输进内锅内，这样在不需要蒸汽的功能时，不安装触发结构，就不会产生蒸汽，即使用户误触发了产生蒸汽的功能，也不会有蒸汽进入内锅内，有效保证了蒸汽使用的可靠性。进一步的，在驱动轴与进气腔之间设置密封件，可进一步提升驱动轴与进气腔之间密封的可靠性，而不单单依靠驱动轴与进气腔之间的机械结构。并且，设置密封件，也方便了驱动轴与进气腔之间的拆卸。4. The drive shaft is equipped with a one-way valve and a trigger part, so that only after the drive section and the connecting section are installed in place, the steam delivery pipeline can conduct and realize steam transmission. When the connecting section is not installed, the one-way valve is not triggered. Steam will be transmitted into the inner pot, so when the steam function is not needed, no trigger structure is installed, and no steam will be generated. Even if the user accidentally triggers the steam generation function, no steam will enter the inner pot, which is effective Ensure the reliability of steam use. Further, the sealing element is arranged between the drive shaft and the air inlet cavity, which can further improve the reliability of the seal between the drive shaft and the air inlet cavity, instead of relying solely on the mechanical structure between the drive shaft and the air inlet cavity. In addition, the sealing element is also convenient for disassembly between the drive shaft and the air inlet cavity.
5.设置进气腔，蒸汽管路可通过***方式来实现连通，即保证了蒸汽由中空的蒸汽管路来传输，同时，蒸汽管路也可拆卸设置，这样，对于蒸汽管路的清洗、维护等带来更大的方便，同时，对于不同的产品以及不同的功能需求，可更换不同的蒸汽管路，实现多功能的目的。例如，在不需要搅拌的功能中，可仅设置带蒸汽管路的中空管即可实现蒸汽传输，满足蒸的功能需求即可，而不再需要中空管实现驱动的功能，当然通用驱动轴来实现蒸汽的传输，只需在程序中控制驱动源不工作，即可实现蒸的功能；对于蒸汽量需求不同的功能，可更换不同传输内径的蒸汽管路，来满足相应的功能。而对于不需要蒸汽功能时，可通过设置非中空的蒸汽管路来封闭蒸汽管路，从根源上防止蒸汽外泄。同时，设置进气腔，特别是进气腔 与中空的蒸汽管路在截面上具有明显的差异，这样，由蒸汽发生器产生的蒸汽会在进气腔内产生缓冲，并重新在进气腔内集聚并通入蒸汽管路内，这样，蒸汽发生器可能产生的压力变化，特别是压力不稳定，会在进气腔内得以缓解，并形成稳定的压力蒸汽由蒸汽管路传输入容纳腔内。同时，对于蒸汽发生器本身产生的水汽或者聚结的水滴，也会在进气腔内凝结，而不会进一步传输进容纳腔内，保证了进入容纳腔的蒸汽纯度，确保食材加工可靠。5. The air inlet cavity is set, and the steam pipeline can be connected by inserting, which ensures that the steam is transmitted by the hollow steam pipeline. At the same time, the steam pipeline can also be detached. In this way, for the cleaning of the steam pipeline, Maintenance and so on bring greater convenience. At the same time, for different products and different functional requirements, different steam lines can be replaced to achieve multi-functional purposes. For example, in a function that does not require stirring, only a hollow tube with a steam pipeline can be used to achieve steam transmission to meet the functional requirements of steaming. The hollow tube is no longer needed to achieve the driving function. Of course, the universal drive The shaft realizes the steam transmission, and the steaming function can be realized by controlling the driving source not to work in the program; for functions with different steam requirements, steam pipes with different transmission inner diameters can be replaced to meet the corresponding functions. When the steam function is not needed, a non-hollow steam pipe can be set to close the steam pipe to prevent the steam from leaking from the source. At the same time, the air inlet cavity is set, especially the air inlet cavity and the hollow steam pipeline have obvious differences in cross section. In this way, the steam generated by the steam generator will be buffered in the air inlet cavity and re-enter the air inlet cavity. It is internally gathered and passed into the steam pipeline. In this way, the possible pressure changes of the steam generator, especially the unstable pressure, will be relieved in the intake cavity, and a stable pressure steam is formed and transmitted into the containment cavity through the steam pipeline. Inside. At the same time, the water vapor or coalesced water droplets generated by the steam generator itself will also condense in the air inlet cavity without being further transmitted into the containing cavity, ensuring the purity of the steam entering the containing cavity and ensuring reliable food processing.
6.驱动轴贯穿所述进气腔且伸出端封闭，驱动源可在驱动轴的下端对驱动轴进行驱动，结构简单，连接方便。通气孔设置于驱动轴的侧壁，蒸汽在由通气孔进入驱动轴内部时，会在通气孔处进行变向，同时由于蒸汽在进气腔内产生的旋流，蒸汽得以在驱动轴内集中，蒸汽在驱动轴内的传输效率高，传输稳定可靠，进而使得空气炸锅的加工稳定可靠。6. The drive shaft penetrates the air inlet cavity and the protruding end is closed. The drive source can drive the drive shaft at the lower end of the drive shaft. The structure is simple and the connection is convenient. The vent hole is arranged on the side wall of the drive shaft. When steam enters the drive shaft from the vent hole, it will change direction at the vent hole. At the same time, due to the swirling flow generated by the steam in the intake cavity, the steam can be concentrated in the drive shaft , The steam transmission efficiency in the drive shaft is high, and the transmission is stable and reliable, which makes the processing of the air fryer stable and reliable.
7.进气腔设置为圆盘状，一方面可通过改变蒸汽传输路径的有效截面尺寸，来提升蒸汽传输压力的稳定性，另一方面，圆盘状的进气腔，进气口由侧壁进，而出气口设置于中心，利于蒸汽的整体流动，蒸汽由侧壁向中心集聚，同样有利于蒸汽压力的稳定，再者，圆盘状的进气腔在轴向上不占据更多空间，而充分利用于空气炸锅本身在径向上尺寸较大的特性，不会改变现有空气炸锅的尺寸，防止体积过大造成的用户满意度下降。进气口沿所述进气腔径向设置，且进气口中心的延长线不通过进气腔中心，驱动轴由轴向***进气腔内，这样，由进气口进入进气腔内的蒸汽，不会直接由出气口排出，而是会在进气口行进路径上与进气腔相互碰撞，蒸汽发生器直接产生的压力不稳定的蒸汽会在进气腔内充分释放压力，并在进 气腔内重新集聚后，再由出气口排出，形成稳定的压力输出。而驱动轴由轴向***进气腔内，使得蒸汽在进入驱动轴内部时再发生方向变化，特别的，进入进气腔内的蒸汽会在进气腔内形成旋流，而旋流的中心即进气腔的中心，而驱动轴由进气腔中心***，旋流蒸汽集聚后即由驱动轴排出，不会在进气腔内残留，使得整体蒸汽传输路径平衡，传输稳定可靠。7. The air inlet cavity is set in a disc shape. On the one hand, the stability of the steam transmission pressure can be improved by changing the effective cross-sectional size of the steam transmission path. On the other hand, the disc-shaped air inlet cavity has the air inlet from the side. The wall enters and the air outlet is set in the center, which is conducive to the overall flow of steam. The steam gathers from the side wall to the center, which is also conducive to the stability of steam pressure. Furthermore, the disc-shaped air inlet cavity does not occupy more in the axial direction. The space is fully utilized for the large radial size of the air fryer itself, which will not change the size of the existing air fryer, and prevent the user satisfaction from being too large. The air inlet is arranged radially along the air inlet cavity, and the extended line of the air inlet center does not pass through the air inlet cavity center, and the drive shaft is inserted into the air inlet cavity from the axial direction, so that the air inlet enters into the air inlet cavity The steam will not be directly discharged from the air outlet, but will collide with the air inlet cavity on the path of the air inlet. The unstable steam directly generated by the steam generator will fully release the pressure in the air inlet cavity, and After re-accumulation in the air inlet cavity, it is discharged from the air outlet to form a stable pressure output. The drive shaft is inserted into the intake cavity from the axial direction, so that the direction of the steam changes when it enters the drive shaft. In particular, the steam entering the intake cavity will form a swirl in the intake cavity, and the center of the swirl That is, the center of the air inlet cavity, and the drive shaft is inserted from the center of the air inlet cavity, and the swirling steam is discharged from the drive shaft after gathering, and will not remain in the air inlet cavity, so that the overall steam transmission path is balanced and the transmission is stable and reliable.
8.在进气腔内设置收缩台阶，使得进气腔内形成缓冲区和导通区，并且缓冲区等级截面面积大于导通区等级截面面积，这样由进气口进入的蒸汽，产生在缓冲区内缓释压力，同时，残留在蒸汽内的水珠也会在缓冲区内凝结。经缓冲区释放压力后，蒸汽再进入导通区，而由于缓冲区和导通区之间截面的变化，进入导通区的蒸汽压力增加，利于蒸汽快速由通气孔进入驱动轴内部，提升蒸汽传输的可靠性。8. Set a contraction step in the air inlet cavity to form a buffer zone and a conduction zone in the air inlet chamber, and the buffer zone's grade cross-sectional area is larger than the conduction zone grade cross-sectional area, so that the steam entering from the air inlet is generated in the buffer The pressure is relieved in the zone, and at the same time, the water droplets remaining in the steam will condense in the buffer zone. After the pressure is released by the buffer zone, the steam enters the conduction zone again. Due to the change of the cross section between the buffer zone and the conduction zone, the pressure of the steam entering the conduction zone increases, which is conducive for the steam to quickly enter the drive shaft from the ventilation hole and raise the steam. Reliability of transmission.
9.搅拌装置设有搅拌桨，搅拌桨套设于驱动轴上端，方便搅拌装置的拆装，对于需要搅拌装置的功能，可安装搅拌装置，对于不需要搅拌功能时，可不安装搅拌装置，使用方便快捷。搅拌桨上设置连通驱动轴内部与内锅内部的蒸汽，使得蒸汽由搅拌装置排出，进而直接与食材进行接触，以对食材进行加工，加工效率高。9. The stirring device is equipped with a stirring paddle. The stirring paddle is set on the upper end of the drive shaft to facilitate the disassembly and assembly of the stirring device. For functions that require a stirring device, a stirring device can be installed. When the stirring function is not required, the stirring device may not be installed and used Convenient. The stirring paddle is provided with steam that communicates the inside of the drive shaft and the inside of the inner pot, so that the steam is discharged from the stirring device, and then directly contacts the food materials, so as to process the food materials with high processing efficiency.
10.出气孔设置于搅拌桨侧壁且位于搅拌叶片上方，在搅拌叶片旋转过程中，出气孔能持续均匀的向内锅内通入蒸汽，而出气孔位于搅拌叶片上方，食材不触及出气孔，能有效防止出气孔被食材堵塞，保证了蒸汽传输管路的可靠性及稳定性。10. The vent hole is arranged on the side wall of the stirring blade and above the stirring blade. During the rotation of the stirring blade, the vent hole can continuously and uniformly pass steam into the inner pot, and the vent hole is located above the stirring blade, and the food does not touch the vent hole , It can effectively prevent the air outlet from being blocked by the food, and ensure the reliability and stability of the steam transmission pipeline.
11.将热风组件中心偏离炸锅组件中心，特别是热风组件中心至铰接中心距离小于炸锅组件中心至铰接中心距离，这样使得热风组件中心离炸锅 组件外边缘的距离增大，将可视窗环绕热风组件设置时，可视窗位于热风组件外边缘至炸锅组件外边缘的区域距离增大，可视面积增大，这样，在保证了热风组件与炸锅组件比例需求的前提下，保证了可视窗的有效利用面积，提高了可视效果。并且，这样的设置，是直接增加了可视窗在投影截面的面积，而非利用空间的角度来增加视角，使用者可通过可视窗直接观察到炸锅组件内食材状态，无需变换角度即可充分观察。由于可视窗实际观察面积的增大，无需再通过提高盖体的高度来增大竖向观察面积，盖体在竖直方向高度可以降低，从而使得盖体及整体的重心降低，对于整机的操控及工作稳定性得以大大改善。热风组件中心距离铰接中心距离缩小，同样有利于控制盖体及整机的重心，当盖体在打开或扣合时，热风组件中心相对于铰接中心的旋转半径小，旋转线速度小，受到的扭力及扭矩小，使用者使用较小的力即可方便操控。当盖体处于打开状态时，热风组件中心距铰接中心距离小，离操控台的高度也足够小，而由于盖体大部分质量集中于热风组件，盖体的重心也随之向下偏移，从而进一步提升了整机的稳定性。进一步设置蒸汽组件，使得空气炸锅同时具有蒸的功能，扩大了空气炸锅的使用功能，并且增加蒸功能不需要特别增大产品体积，功能增加快捷，产品实用性更佳。将蒸汽输送管路的进气口偏离热风组件中心设置。首先，蒸汽由底壁进入炸锅组件，而蒸汽自身的特性会向上移动，这样，进入炸锅组件内的蒸汽能快速在炸锅组件内扩散以填充整体炸锅组件，加工效率高；同时，蒸汽不会直接上升冲击热风组件，防止蒸汽对热风组件的影响，而利用热风组件偏心形成的气流，蒸汽会顺着气流在内锅内快速流动，以对食材进行加热，加热效率高。11. Move the center of the hot air assembly away from the center of the fryer assembly, especially the distance from the center of the hot air assembly to the hinge center is less than the distance from the center of the fryer assembly to the hinge center, so that the distance between the center of the hot air assembly and the outer edge of the fryer assembly will increase, and the window will be visible. When the hot air component is arranged around the hot air component, the distance between the visible window from the outer edge of the hot air component to the outer edge of the frypot component increases, and the visible area increases. In this way, the ratio of the hot air component to the frypot component is ensured. The effective use of the window area improves the visual effect. Moreover, this arrangement directly increases the area of the visible window in the projected section, instead of using the angle of space to increase the viewing angle. The user can directly observe the state of the ingredients in the fryer assembly through the visible window without changing the angle. Observed. Due to the increase in the actual observation area of the viewing window, there is no need to increase the height of the cover to increase the vertical observation area. The height of the cover in the vertical direction can be reduced, which reduces the center of gravity of the cover and the whole. The handling and working stability have been greatly improved. The distance between the center of the hot air assembly and the hinge center is reduced, which is also beneficial to control the center of gravity of the cover and the whole machine. When the cover is opened or buckled, the center of the hot air assembly has a small rotation radius relative to the hinge center, and the linear speed of rotation is small. The torque and torque are small, and the user can easily control it with a small force. When the cover is in the open state, the distance between the center of the hot air assembly and the hinge center is small, and the height from the console is also small enough. Since most of the mass of the cover is concentrated in the hot air assembly, the center of gravity of the cover also shifts downward. This further improves the stability of the whole machine. The steam component is further provided, so that the air fryer has the steaming function at the same time, which expands the use function of the air fryer, and adding the steaming function does not require a special increase in product volume, the function is increased quickly, and the product practicability is better. Set the air inlet of the steam delivery pipeline away from the center of the hot air assembly. First, the steam enters the fryer assembly from the bottom wall, and the characteristics of the steam itself will move upwards. In this way, the steam entering the fryer assembly can quickly diffuse in the fryer assembly to fill the entire fryer assembly, and the processing efficiency is high; at the same time, The steam will not directly rise and impact the hot air components to prevent the steam from affecting the hot air components. Using the eccentric air flow formed by the hot air components, the steam will flow quickly along the air flow in the inner pot to heat the food, and the heating efficiency is high.
12.在盖体上设置排出管路，所述排气进口位于导风板顶壁，蒸汽在上升并完成加工后从排出管路排出，顺应了蒸汽自然流动的方向，即使当产品仅利用蒸的功能时，热风组件不工作，加热件及风扇不会带动炸锅组件内部加热及扰流，蒸汽自身的热量及流向，也能满足产品对于蒸功能的支持，并且加热效率得以保证。而进一步的，当风扇在工作时，会将排气进口的空气及蒸汽向四周吹离，将压迫蒸汽更多的在炸锅组件内部循环，相当于提高了炸锅组件内部蒸汽的压力，起到一定的增压效果，从而进一步提升蒸汽的加热效率。12. Set up a discharge pipeline on the cover. The exhaust inlet is located on the top wall of the air deflector. The steam is discharged from the discharge pipeline after rising and processing, which conforms to the direction of the natural flow of steam, even when the product only uses steam When the function of the hot air component does not work, the heating element and fan will not drive the internal heating and turbulence of the fryer component. The heat and flow direction of the steam itself can also satisfy the product’s support for the steaming function, and the heating efficiency can be guaranteed. Furthermore, when the fan is working, the air and steam at the exhaust inlet will be blown away, and the compressed steam will circulate more inside the fryer assembly, which is equivalent to increasing the pressure of the steam inside the fryer assembly. To a certain boost effect, thereby further improving the steam heating efficiency.
13.排气进口距所述铰接中心的距离小于热风组件中心距铰接中心的距离，这样，从空气炸锅前侧至铰接中心上，依次设置炸锅组件中心(包含蒸汽进口)、热风组件中心及排气进口，蒸汽由进口至出口，能在炸锅组件内部存留足够的时间，充分保证了蒸汽的加热效率。13. The distance between the exhaust inlet and the hinge center is less than the distance between the center of the hot air assembly and the hinge center, so that from the front side of the air fryer to the hinge center, the center of the fryer assembly (including the steam inlet) and the center of the hot air assembly are arranged in sequence And the exhaust inlet, the steam from the inlet to the outlet, can stay in the fryer assembly for enough time, fully ensuring the steam heating efficiency.
14.排气出口相较排气进口更偏向铰接轴设置，蒸汽由排气出口排出后远离使用者，防止排出蒸汽影响甚至烫伤使用者，既保证了空气炸锅的加热效率，还使得使用者体验舒适度大大提升。14. The exhaust outlet is more inclined to the hinged shaft than the exhaust inlet. After the steam is discharged from the exhaust outlet, it is far away from the user to prevent the exhaust steam from affecting or even scalding the user. This not only ensures the heating efficiency of the air fryer, but also makes the user Experience comfort is greatly improved.
15.同时设置外视窗、内视窗，并且外视窗倾斜设置，而内视窗横向延伸，以与盖体合围构成可视腔。将内视窗横向延伸设置，在竖向高度上不占用空间，也使得盖体整体的高度可设置为足够小，可充分压缩盖体的高度，即保证了盖体及整机的重心下移，提高稳定性；同时，还可使得盖体及整机的尺寸缩减，避免整机占据更多空间，对于消费者使用及收纳都存在很大便利。通过设置可视腔，以隔断炸锅组件内部和外部的热量交换，避免盖体外部温度过高，防止对使用者造成伤害。同时，可视腔还可避免 内外部温度造成的冷凝现象，避免由于冷凝造成无法正常观察到炸锅组件内部的情况。外视窗倾斜设置，不影响内视窗及盖体底面的设置，不会造成盖体及整机的高度增加，倾斜设置的外视窗，使得可视腔体积增大，对于温度的隔断性能更佳，效果更好。15. At the same time, an outer window and an inner window are arranged, and the outer window is inclinedly arranged, and the inner window extends laterally to form a visual cavity surrounded by the cover. Extending the inner window horizontally does not occupy space in the vertical height, and also makes the overall height of the cover small enough to fully compress the height of the cover, that is, to ensure that the center of gravity of the cover and the whole machine moves down. Improve stability; at the same time, it can also reduce the size of the cover and the whole machine, avoiding the whole machine from occupying more space, which is very convenient for consumers to use and store. The visual cavity is provided to block the heat exchange between the inside and outside of the fryer assembly, avoiding the external temperature of the cover from being too high, and preventing damage to the user. At the same time, the visual cavity can also avoid condensation caused by the internal and external temperature, and avoid the failure to observe the inside of the fryer assembly due to condensation. The inclined setting of the outer window does not affect the setting of the inner window and the bottom surface of the cover, and will not increase the height of the cover and the whole machine. The inclined outer window increases the volume of the visual cavity and has better temperature insulation performance. Better results.
16.内视窗贴合内锅上端，可进一步压低可视窗及盖体的高度，进一步减小了炸锅组件上方多余的加热空间，还使得产品尺寸尽量小巧，满足消费者追求体积小、操控及搬动方便的需求。直接在内视窗上设置安装孔，导风板贯穿安装孔并与内视窗连接，导风板可直接作用于内锅内部，保证了加热高效，热风流向食材的路径缩短，当监测内锅内的温度时，与加热件之间的距离更短，监测更准确，同时，也更利于对加热件的控制。导风板与内视窗之间设置密封件，可避免热风，特别是蒸汽由导风板与内视窗之间缝隙进入盖体内部，防止盖体内部的器件被高温或者蒸汽损坏。16. The inner window is attached to the upper end of the inner pot, which can further reduce the height of the window and the lid, further reduce the excess heating space above the fryer assembly, and make the product size as small as possible to meet consumers' pursuit of small size, control and The need to move easily. The installation hole is set directly on the inner window. The wind deflector penetrates the installation hole and is connected to the inner window. The wind deflector can directly act on the inside of the inner pot to ensure efficient heating and shorten the path of hot air flowing to the food. When monitoring the inner pot At temperature, the distance from the heating element is shorter, the monitoring is more accurate, and at the same time, it is more conducive to the control of the heating element. A seal is arranged between the wind deflector and the inner window to prevent hot air, especially steam, from entering the cover through the gap between the wind deflector and the inner window, and to prevent the components inside the cover from being damaged by high temperature or steam.
17.内视窗与外视窗通过视窗连接件连接，保证了可视窗连接的可靠。特别的，将内视窗设置为更卫生及方便清洁的玻璃材质，而将外视窗设置为更方便制作曲面造型的塑料材质，通过连接件连接，避免了不同材质变形不同的影响。内视窗下方设置密封圈，内锅上端设置翻边，进一步提升内视窗与内锅之间的密封。17. The inner window and the outer window are connected by a window connector, which ensures the reliability of the window connection. In particular, the inner window is set to a glass material that is more hygienic and convenient to clean, and the outer window is set to a plastic material that is more convenient to make curved shapes, and connected by connecting pieces to avoid the different effects of different materials. A sealing ring is arranged under the inner window, and a flange is arranged on the upper end of the inner pot to further improve the seal between the inner window and the inner pot.

如图17所示，所述空气炸锅在水平面的投影简要示图，所述铰接轴100中心在水平面的投影为O，所述热风组件中心在水平面的投影为P，所述炸锅组件中心在水平面的投影为Q，所述热风组件中心和铰接中心的连线为OP，所述炸锅组件中心和铰接中心的连线为OQ，两者之间的夹角为α，α≤10°。优选的，所述α＝0°，即所述炸锅组件中心、热风组件中心、铰接中心在水平面的投影在一条线上。这样设置的好处在于：两者之间的夹角较小设置，特别是直接设置在一条线上，这样，可视窗位于空气炸锅前部也即使用者一侧的长度及面积最大，保证了使用者能从可视窗方便观察炸锅组件内食材。如果夹角设置过大，虽然不影响可视窗的面积，但可视窗偏离使用者位置，使得使用者观察不便；同时，还使得热风组件相对偏离至一侧，重心偏置，当打开盖体时，偏置的热风组件使得盖体晃动增加，进而使得产品放置不稳，操控产便，甚至存在产品倾倒的风险。As shown in Figure 17, the projection of the air fryer on the horizontal plane is a brief view, the projection of the center of the hinge shaft 100 on the horizontal plane is O, the projection of the center of the hot air assembly on the horizontal plane is P, the center of the fryer assembly The projection on the horizontal plane is Q, the line between the center of the hot air assembly and the hinge center is OP, the line between the center of the fryer assembly and the hinge center is OQ, and the angle between the two is α, α≤10° . Preferably, the α=0°, that is, the projections of the center of the fryer assembly, the center of the hot air assembly, and the hinge center on the horizontal plane are in a line. The advantage of this setting is that the angle between the two is small, especially directly on a line, so that the length and area of the window located at the front of the air fryer, that is, the user’s side, is the largest, ensuring The user can conveniently observe the ingredients in the fryer assembly from the viewing window. If the included angle is set too large, although it does not affect the area of the visible window, the visible window deviates from the user's position, which makes it inconvenient for the user to observe; at the same time, the hot air component is relatively deviated to one side and the center of gravity is offset. When the cover is opened , The biased hot air component increases the shaking of the cover, which in turn makes the product unstable, manipulates the stool, and even risks the product to fall.
如图18、19所示，所述盖体10及机座15分别包括加工区及连接区，如箭头所示，正常使用者在前侧操控所述空气炸锅，故加工区设置于空气炸锅的前侧，而连接区设置于加工区的后侧，也即远离使用者一侧，这样，当盖体处于打开状态时，向连接区倾斜，从而保证了处于加工区的炸锅组件能充分打开，方便使用者正常操作。As shown in Figures 18 and 19, the cover 10 and the base 15 respectively include a processing area and a connection area. As shown by the arrow, normal users control the air fryer on the front side, so the processing area is set in the air fryer. The front side of the pot, and the connection area is arranged on the back side of the processing area, that is, the side away from the user. In this way, when the lid is in an open state, it is inclined to the connection area, thereby ensuring that the fryer assembly in the processing area can Fully open, convenient for users to operate normally.
本实施例中，所述炸锅组件设置为桶形，所述机座15的加工区部分设置为与之相配合的圆柱形，所述机座15的连接区设置为与之形成相配的圆柱形，并在外侧相切连接以构成机座15的主体形状。所述盖体10的连接区为与机座15的连接区半径相同的圆柱状，盖体10的加工区设置为与连 接区半径相同的圆柱状，并在外侧相切连接以构成盖体10的主体形状，并构成所述安装部。所述可视窗7环绕所述盖体10加工区设置，其底部与机座15形状相配合，上部与盖体连接，使得所述可视窗7形成为不规则的曲面造型。具体的，所述外视窗72为曲面造型，所述内视窗71为平面造型。In this embodiment, the fryer assembly is configured in a barrel shape, the processing area of the base 15 is configured to be a cylindrical shape that is matched with it, and the connection area of the base 15 is configured to form a matched cylinder. The main body shape of the base 15 is formed by tangent connection on the outside. The connecting area of the cover body 10 is cylindrical with the same radius as the connecting area of the base 15, and the processing area of the cover body 10 is set in a cylindrical shape with the same radius as the connecting area, and is connected tangentially on the outside to form the cover 10 The main body shape and constitute the mounting part. The visible window 7 is arranged around the processing area of the cover body 10, the bottom of which matches the shape of the base 15 and the upper part is connected with the cover body, so that the visible window 7 is formed into an irregular curved surface. Specifically, the outer window 72 has a curved surface shape, and the inner window 71 has a planar shape.
所述炸锅组件有效半径为R，所述炸锅组件中心距所述铰接轴中心在水平面的投影距离为L，且1.1≤L/R≤2。这样设置的好处在于：连接区设置于机座的后侧，当打开盖体时，盖体向后旋转，从使用者角度而言，炸锅组件能充分打开，方便使用者对于炸锅组件内食材的操控。如果L/R设置过小，则盖体与机座的连接区与加工区分隔不明显，炸锅组件的外侧与铰接轴中心距离过小，当盖体打开时，盖体与炸锅组件的分离不足，不利于使用者对于炸锅组件内食材的操控，并且，盖体与炸锅组件相对距离较近，使用者在操控炸锅组件内食材时，容易碰触到热风组件，存在被热风组件伤害的危险。如果L/R设置过大，则盖体的旋转半径过大，特别是热风组件的旋转半径较大，盖体打开占据的空间比较大，以及盖体打开过程中受到的扭力以及造成的动能较大，即不利用操控机器，还使得产品打开时晃动增加，整机工作不稳。The effective radius of the fryer assembly is R, and the projection distance of the center of the fryer assembly from the center of the hinge axis on the horizontal plane is L, and 1.1≤L/R≤2. The advantage of this arrangement is that the connection area is set on the rear side of the machine base. When the cover is opened, the cover rotates backwards. From the user's point of view, the fryer assembly can be fully opened, which is convenient for the user to access the fryer assembly. Manipulation of ingredients. If the L/R setting is too small, the connection area between the lid body and the machine base is not clearly separated from the processing area, and the distance between the outer side of the fryer assembly and the center of the hinge axis is too small. When the lid body is opened, the distance between the lid body and the fryer assembly Insufficient separation is not conducive to the user's manipulation of the ingredients in the fryer assembly. Moreover, the cover is relatively close to the fryer assembly. When the user manipulates the ingredients in the fryer assembly, it is easy for the user to touch the hot air assembly. Risk of component injury. If the L/R setting is too large, the rotation radius of the cover is too large, especially the hot air assembly has a large rotation radius, the cover opening takes up more space, and the torsion and kinetic energy received during the opening of the cover are relatively large. Large, that is, it does not use the control machine, but also increases the shaking when the product is opened, and the whole machine is unstable.
所述安装部顶部设置为平面，所述安装部前侧设置操控区134，所述安装腔内部对应操控区134设有操控线路板131。本实施例中，所述操控区设置为触控开关，并且仅当产品通电后在操控区显示对应的功能。所述安装腔设有与外部连通的进风口132及出风口133，所述进风口132设置于为两个，分别位于所述安装部顶部两侧，所述出风口133位于所述安装部后侧。所述冷风风扇115将外部的冷空气从进风口132吸入，流过操控 线路板131、风扇电机114等部件后，再从出风口133排出，避免安装腔内温度过高对各部件产生影响。所述进风口132及出风口133可设置为多个均布的小孔，以避免从进风口或出风口伸入安装腔内部而产生的危险，同时也可避免虫子等爬入。将进风口设置于两侧，冷空气进入后可直接流向线路板及风扇电机，增加了冷却的效率；将出风口设置于后侧，排出的热风不会对使用者造成影响，同时，还避免了排出的热风被重新吸入安装腔内。The top of the mounting part is set to be flat, the front side of the mounting part is provided with a control area 134, and the inside of the installation cavity is provided with a control circuit board 131 corresponding to the control area 134. In this embodiment, the control area is set as a touch switch, and the corresponding function is displayed in the control area only when the product is powered on. The installation cavity is provided with an air inlet 132 and an air outlet 133 communicating with the outside, the air inlet 132 is provided in two, which are respectively located on both sides of the top of the installation part, and the air outlet 133 is located behind the installation part side. The cold air fan 115 sucks in the external cold air from the air inlet 132, flows through the control circuit board 131, the fan motor 114 and other components, and then discharges it from the air outlet 133 to avoid excessive temperature in the installation cavity from affecting the components. The air inlet 132 and the air outlet 133 can be arranged as a plurality of evenly distributed small holes to avoid the danger of extending into the installation cavity from the air inlet or the air outlet, and also to prevent insects from crawling in. Set the air inlet on both sides, and the cold air can flow directly to the circuit board and fan motor after entering, increasing the cooling efficiency; set the air outlet on the back side, the hot air discharged will not affect the user, and at the same time, avoid The discharged hot air is sucked into the installation cavity again.
如图20所示，所述盖体10还设有蒸汽排出管路，所述蒸汽排出管路包括排气进口63、排气出口64及排气管65，排气管65连接排气进口63及排气出口64。所述排气进口63位于所述导风板111的顶壁，所述导风板111的顶壁设有排出孔1112，所述排气进口63密封安装于所述排出孔1112。所述排气出口64包括泄压仓641及泄压盖642，泄压盖642上设有蒸汽出口643。所述泄压仓641呈上大下小的漏斗状，底部通过排气管65与排气进口63连通，泄压仓641上部被泄压盖642遮挡，泄压盖642设有倾斜向后上方设置的蒸汽出口643。蒸汽由排气进口63进入蒸汽排出管路，通过排气管65进入泄压仓641内，由于体积的增大，蒸汽会在泄压仓641内凝结，从而避免了过多的蒸汽排出时造成的不便，多余的蒸汽进一步通过蒸汽出口643排出，蒸汽出口643向后方设置，不会对使用者造成影响，而倾斜向上，使得蒸汽能顺着向上的方向快速排出而消散。As shown in FIG. 20, the cover body 10 is also provided with a steam discharge pipeline. The steam discharge pipeline includes an exhaust inlet 63, an exhaust outlet 64, and an exhaust pipe 65. The exhaust pipe 65 is connected to the exhaust inlet 63. And exhaust outlet 64. The exhaust inlet 63 is located on the top wall of the wind deflector 111, the top wall of the wind deflector 111 is provided with an exhaust hole 1112, and the exhaust inlet 63 is sealed and installed in the exhaust hole 1112. The exhaust outlet 64 includes a pressure relief chamber 641 and a pressure relief cover 642, and the pressure relief cover 642 is provided with a steam outlet 643. The pressure relief bin 641 is in the shape of a funnel with a large top and a small bottom. The bottom of the pressure relief bin 641 is connected to the exhaust inlet 63 through an exhaust pipe 65. The upper part of the pressure relief bin 641 is covered by a pressure relief cover 642. Set the steam outlet 643. The steam enters the steam discharge pipeline from the exhaust inlet 63, and enters the pressure relief bin 641 through the exhaust pipe 65. Due to the increase in volume, the steam will condense in the pressure relief bin 641, thereby avoiding excessive steam discharge. Inconvenience, the excess steam is further discharged through the steam outlet 643. The steam outlet 643 is set to the rear without affecting the user. It is inclined upward so that the steam can be quickly discharged and dissipated in the upward direction.
所述炸锅组件中心距所述铰接轴在水平面的投影距离为L，也即所述蒸汽输送管路的进气口距所述铰接轴中心的距离为L，所述热风组件中心距所述铰接轴在水平面上的投影距离为L1，所述排气进口中心距所述铰接 轴中心在水平面上的投影距离为L2，所述排气出口中心距所述铰接轴中心在水平面上的投影跨度为L3，L>L1>L2>L3。这样，蒸汽由蒸汽输送管路注入炸锅组件后，由炸锅组件中心向四周均匀分散，同时蒸汽自然向上上升并漫延，使得蒸汽能快速注入炸锅组件内部并对食材进行加工，而热风组件偏心设置，中心进气的蒸汽不会直接对热风组件进行冲击，避免了热风组件在蒸汽冲击下快速老化，保证了热风组件的正常使用寿命。而偏心设置的热风组件，在需要吹风加工状态时，同样可起到对蒸汽进行扰流的功能，以使蒸汽能更高效地对食材进行加工。而排气进口相对热风组件更靠近铰接轴中心，使得排气进口与蒸汽进口在距离上相对更远，蒸汽在炸锅组件内部运行的距离相对更长，蒸汽使用效率更高。而当热风组件工作时，由于排气进口位于导风板顶壁，风扇吹动蒸汽并使蒸汽远离排气进口，使得蒸汽不易直接从排气进口排出，使得蒸汽在炸锅组件内部形成一定的压力，能更加高效的对食材完成加工。排气出口相对排气进口在水平面上更靠近铰接轴，使得排气出口距使用者更远，由排气出口排出的蒸汽不会对使用者造成影响，而同时，将蒸汽出口斜向后排出，更加远离使用者，使用更安全可靠。The projection distance of the center of the fryer assembly to the hinge axis on the horizontal plane is L, that is, the distance between the air inlet of the steam delivery pipeline and the center of the hinge axis is L, and the center of the hot air assembly is The projection distance of the hinge axis on the horizontal plane is L1, the projection distance of the center of the exhaust inlet from the center of the hinge axis on the horizontal plane is L2, and the projection span of the center of the exhaust outlet from the center of the hinge axis on the horizontal plane For L3, L>L1>L2>L3. In this way, after the steam is injected into the fryer assembly from the steam delivery pipeline, it is evenly dispersed from the center of the fryer assembly to the surroundings. At the same time, the steam naturally rises and spreads, so that the steam can be quickly injected into the fryer assembly and process the food, while the hot air assembly The eccentric setting prevents the steam from the center intake from directly impacting the hot air components, avoiding the rapid aging of the hot air components under steam impact, and ensuring the normal service life of the hot air components. The eccentrically arranged hot air component can also function as a turbulence for steam when it needs to be blown and processed, so that the steam can process the food more efficiently. Compared with the hot air assembly, the exhaust inlet is closer to the center of the hinged shaft, so that the exhaust inlet and the steam inlet are relatively farther apart, the steam travels in the fryer assembly relatively longer, and the steam use efficiency is higher. When the hot air assembly is working, because the exhaust inlet is located on the top wall of the air deflector, the fan blows the steam and keeps the steam away from the exhaust inlet, making it difficult for the steam to be directly discharged from the exhaust inlet, so that the steam forms a certain amount inside the fryer assembly. Pressure can process the food more efficiently. The exhaust outlet is closer to the hinge axis on the horizontal plane than the exhaust inlet, so that the exhaust outlet is further away from the user. The steam discharged from the exhaust outlet will not affect the user. At the same time, the steam outlet is discharged diagonally backward , Farther away from users, safer and more reliable to use.
综上，通过将驱动轴中空设置，在现有产品不做大的变更的基础上，可增加蒸的功能，拓展现有产品的功能，并且，相较现有技术中仅仅在内部增加加湿结构，本发明设置可控制的蒸汽发生器，在加工过程中，蒸汽的进气时间、进气量均可控，并且，蒸汽发生器单独设置，不会影响空气炸锅本身加热件的效率，空气炸锅本身的加工效率得以保证。通过将热风组件与炸锅组件偏离设置，并且将热风组件更靠近铰接轴中心设置，满足 热风组件偏心带来的扰流改善。特别是，增加在可视窗在使用者位置的有效使用面积，使得使用者可方便的通过可视窗来观察容纳腔内状态，并且无需变换视角即可完全观察到炸锅组件内部。观察面积的增大，可视窗无需再在高度方向上增加，从而使得盖体及整体高度的降低，即压缩了整机占用的空间，还使得容纳腔有效利用比例增加，避免了热能的浪费。盖体高度的降低，以及热风组件偏向铰接轴设置，使得热风组件离铰接轴距离更近，当打开盖体时，热风组件受到的力矩及线速度更小，动能小，方便使用者对于盖体的操控，同时盖体及整体在操控时更平稳。所述空气炸锅增设蒸汽组件，扩大了产品的使用功能，不单单具有烘烤功能，同时还可实现单蒸、单烘烤、烘烤+蒸等不同的组合，提升使用者的满意度。蒸汽进口设置于炸锅组件的中心，方便蒸汽快速在炸锅组件内分散注入，提升蒸的加工效率。加热组件与炸锅组件中心也即蒸汽进口偏心设置，即起到扰流效果，又可防止蒸汽直接对加热组件的冲击。而加热组件相对靠近铰接轴中心，保证了可视窗位于使用者位置的可视面积。优选的，可视窗包括外视窗及内视窗，并构成密闭的可视腔，可视腔可阻隔容纳腔体内外的温度差，避免由于温差而产生的冷凝现象，保证了观察可靠。In summary, by hollowing the drive shaft, the steaming function can be added and the function of the existing product can be expanded on the basis of no major changes to the existing product, and compared with the prior art, only a humidification structure is added inside , The present invention is equipped with a controllable steam generator. During the processing process, the steam intake time and air intake volume can be controlled. Moreover, the independent setting of the steam generator will not affect the efficiency of the heating element of the air fryer itself. The processing efficiency of the fryer itself is guaranteed. By deviating the hot air assembly from the fryer assembly and placing the hot air assembly closer to the center of the hinge axis, the turbulence improvement caused by the eccentricity of the hot air assembly can be met. In particular, the effective use area of the visible window at the user's position is increased, so that the user can conveniently observe the state of the accommodating cavity through the visible window, and can completely observe the inside of the fryer assembly without changing the viewing angle. With the increase of the observation area, the viewing window does not need to increase in the height direction, so that the cover and the overall height are reduced, that is, the space occupied by the whole machine is compressed, and the effective utilization ratio of the containing cavity is increased, and the waste of heat energy is avoided. The reduction in the height of the cover and the arrangement of the hot air assembly toward the hinge axis make the hot air assembly closer to the hinge axis. When the cover is opened, the torque and linear velocity of the hot air assembly are smaller, and the kinetic energy is small, which is convenient for the user to handle the cover. The control, the cover and the whole are more stable in control. The additional steam component of the air fryer expands the use function of the product, not only has a baking function, but also can realize different combinations of single steaming, single baking, baking + steaming, etc., to improve user satisfaction. The steam inlet is arranged in the center of the fryer assembly to facilitate the rapid injection of steam into the fryer assembly and improve the steaming processing efficiency. The center of the heating component and the fryer component, that is, the steam inlet is eccentrically arranged, which not only has the effect of turbulence, but also prevents the direct impact of steam on the heating component. The heating element is relatively close to the center of the hinge axis, which ensures the visible area of the visible window at the user's position. Preferably, the viewable window includes an outer window and an inner window, and constitutes a closed visual cavity. The visual cavity can block the temperature difference between the inside and outside of the containing cavity, avoid condensation due to the temperature difference, and ensure reliable observation.

实施例二。Example two.
作为本发明所述方便加工的空气炸锅的第二实施例，与第一实施例的 主要差别在于，所述空气炸锅不设置进气腔。As the second embodiment of the easy-to-process air fryer of the present invention, the main difference from the first embodiment is that the air fryer is not provided with an air inlet cavity.
如图21所示，所述空气炸锅包括蒸汽发生器，所述机座内设有蒸汽管61。所述驱动轴中空设置，且中空的驱动轴贯穿设置，使得所述驱动轴下端形成轴孔38，所述蒸汽管61可***所述轴孔38内，所述蒸汽管外侧壁还设有蒸汽管密封圈611，所述蒸汽管密封圈套设于蒸汽管61外，并在蒸汽管61***驱动轴内时与驱动轴内壁相贴合以封闭蒸汽管与驱动轴。As shown in Figure 21, the air fryer includes a steam generator, and a steam pipe 61 is provided in the base. The drive shaft is hollow, and the hollow drive shaft runs through, so that a shaft hole 38 is formed at the lower end of the drive shaft, the steam tube 61 can be inserted into the shaft hole 38, and the outer side wall of the steam tube is also provided with steam The pipe sealing ring 611 is sleeved outside the steam pipe 61 and is attached to the inner wall of the drive shaft when the steam pipe 61 is inserted into the drive shaft to seal the steam pipe and the drive shaft.
所述驱动轴包括驱动段3，所述驱动段3设有驱动段轮314，所述驱动源8设有传输皮带82，所述驱动源8通过传输皮带82驱动所述驱动段轮314以驱动所述驱动轴。所述驱动源8固定于机座内壁。The drive shaft includes a drive section 3, the drive section 3 is provided with a drive section wheel 314, the drive source 8 is provided with a transmission belt 82, and the drive source 8 drives the drive section wheel 314 through the transmission belt 82 to drive The drive shaft. The driving source 8 is fixed on the inner wall of the base.
这样设置的好处在于：蒸汽发生器直接通过蒸汽管与驱动轴连接，蒸汽管与驱动轴直接插接即可，结构实现简单，只需增加蒸汽发生器即可满足蒸功能，同时，蒸汽发生器可设置于容纳腔外部，不会占用空气炸锅加热件本身的功耗，保证了空气炸锅本身加工的稳定可靠。蒸汽管与驱动轴之间设置密封结构，进一步保证了蒸汽传输的可靠性，即使驱动轴相对蒸汽管转动，也能保证蒸汽传输的可靠。蒸汽管直接***驱动轴内部，蒸汽可顺着中空的驱动轴向上快速传输，这也是蒸汽本身自然上升的方向，而蒸汽若反向向下时，会受到蒸汽本身上升的浮力和后续空气的压力，蒸汽泄漏的可能性进一步减小。驱动源通过皮带带动驱动轴旋转，利用皮带本身传输的大传动比，使得驱动源可选择性大大提升，可使用较低成本较高转速的电机来满足驱动需求。The advantage of this arrangement is that the steam generator is directly connected to the drive shaft through the steam pipe, and the steam pipe is directly plugged into the drive shaft. The structure is simple to realize, and the steaming function can be met by adding a steam generator. At the same time, the steam generator It can be arranged outside the accommodating cavity, does not occupy the power consumption of the heating element of the air fryer itself, and ensures the stable and reliable processing of the air fryer itself. The sealing structure is arranged between the steam pipe and the drive shaft to further ensure the reliability of steam transmission. Even if the drive shaft rotates relative to the steam pipe, the reliability of steam transmission can be ensured. The steam pipe is directly inserted into the drive shaft, and the steam can be quickly transmitted up the hollow drive shaft. This is also the direction in which the steam itself naturally rises. If the steam goes down in the opposite direction, it will be affected by the rising buoyancy of the steam itself and the subsequent air. Pressure, the possibility of steam leakage is further reduced.

实施例三。Example three.
作为本发明所述方便加工的空气炸锅的第三实施例，与第一实施例的主要差别在于，所述进气腔内进一步设置进气格栅。As the third embodiment of the easy-to-process air fryer of the present invention, the main difference from the first embodiment is that an air intake grille is further provided in the air intake cavity.
如图22所示，所述进气腔包括进气口20、出气口221，所述进气口位于所述进气腔2的侧部，所述出气口221位于所述进气腔2的中心，所述进气腔内壁还设有进气格栅28，所述进气格栅28设置于所述进气腔2的内侧壁，所述进气格栅28螺旋上升设置，进入进气腔2内的蒸汽可顺着进气格栅28螺旋上升并通过所述出气口221排出。As shown in FIG. 22, the air inlet cavity includes an air inlet 20 and an air outlet 221.

通过设置进气格栅，使得蒸汽在进气腔内的运动路径更加可控。一方面，蒸汽进入进气腔内时，由于体积及有效截面的变化，蒸汽的压力得以释放并重新在进气腔内集聚以形成压力稳定的蒸汽，进而通过驱动轴传输至容纳腔内，保证空气炸锅的加工可靠；另一方面，进气格栅使得蒸汽在进气腔内的运动路径延长，相应的蒸汽在进气腔内存留的时间较长，使得由蒸汽发生器出来压力不稳定的蒸汽，在进气腔内得以充分的释放，从而使得由进气腔排出的蒸汽压力稳定可控，进而使得空气炸锅在加工过程中的稳定可靠。By setting the intake grille, the movement path of the steam in the intake cavity is more controllable. On the one hand, when steam enters the intake cavity, due to the changes in volume and effective cross-section, the pressure of the steam is released and re-accumulates in the intake cavity to form steam with stable pressure, which is then transmitted to the containing cavity through the drive shaft to ensure The processing of the air fryer is reliable; on the other hand, the intake grill extends the steam movement path in the intake cavity, and the corresponding steam stays in the intake cavity for a long time, making the pressure from the steam generator unstable The steam is fully released in the air inlet cavity, so that the pressure of the steam discharged from the air inlet cavity is stable and controllable, thereby making the air fryer stable and reliable during the processing process.
可以理解的，所述进气格栅设置为多条，且相互间隙设置。It is understandable that the air intake grille is arranged in multiples, and they are arranged at intervals.
可以理解的，所述进气口位于所述进气腔侧壁底部，所述出气口位于所述进气腔侧壁顶端，且与所述进气口相对设置，所述蒸汽发生器还包括位于所述出气口的蒸汽管，所述蒸汽发生器通过蒸汽管与驱动轴导通。It is understandable that the air inlet is located at the bottom of the side wall of the air inlet cavity, and the air outlet is located at the top of the side wall of the air inlet cavity and is arranged opposite to the air inlet. The steam generator further includes The steam pipe located at the air outlet, the steam generator is in communication with the drive shaft through the steam pipe.
可以理解的，所述进气口位于所述进气腔侧壁顶部，所述出气口位于所述进气腔底部或侧壁底部，蒸汽由上部进入进气腔并由下部排出进气腔。由于蒸汽本身具有向上的浮力，反向设置的进气腔，使得进气腔内的蒸汽，必需由后续的蒸汽压迫才能更好的由出气口排出，而通过进气腔内体积的变化，使得蒸汽的压力经释放、重新集聚、增压等几重步骤，最终排出的蒸汽压力可控且稳定，保证了食材加工的稳定可靠。蒸汽向下压迫的过程中，残留在蒸汽中的水珠得以凝结，并最终在进气腔内集聚，再通过排水结构等排出，保证了进入容纳腔的蒸汽纯净高效。It can be understood that the air inlet is located at the top of the side wall of the air inlet cavity, and the air outlet is located at the bottom of the air inlet cavity or the bottom of the side wall, and steam enters the air inlet cavity from the upper part and exits the air inlet cavity from the lower part. Due to the upward buoyancy of the steam itself, the oppositely arranged air inlet cavity makes the steam in the air inlet cavity better discharged from the air outlet only by the subsequent compression of steam, and the volume change in the air inlet cavity makes After the steam pressure is released, re-accumulated, and pressurized, the final steam pressure is controllable and stable, which ensures the stability and reliability of food processing. When the steam is pressed downwards, the water droplets remaining in the steam are condensed and finally collected in the intake cavity, and then discharged through the drainage structure, etc., ensuring that the steam entering the containing cavity is pure and efficient.
以上所述者，仅为本发明的较佳实施例而已，并非用来限定本发明的实施范围，即凡依本发明所作的均等变化与修饰，皆为本发明权利要求范围所涵盖，这里不再一一举例。The above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made in accordance with the present invention are covered by the scope of the claims of the present invention. Give another example.
