- This structure that circulates the refrigeration cavity 2211 and the cooking cavity 122 is beneficial to prevent the leakage of cold air, thereby improving the cooling efficiency of the refrigeration component 220 on the cooking cavity 122, so that it can reach the required low temperature state or reach a lower temperature more quickly.
- the two ends of the first vent 232 are directly or indirectly connected to the refrigeration cavity 2211 and the cooking cavity 122 respectively.
- the on-off state of the first vent 232 can control the on-off state of the refrigeration cavity 2211 and the cooking cavity 122.
- the heat-insulating valve core 233 moves relative to the docking seat 231, and has a closed position and an open position on the movement trajectory of the heat-insulating valve core 233. Please refer to Figure 11. When the heat-insulating valve core 233 is in the closed position, the heat-insulating valve core 233 cuts off the first vent 232 to isolate the cooking cavity 122 from the refrigeration cavity 2211; please refer to Figure 9.
- the heat-insulating valve core 233 When the heat-insulating valve core 233 is in the open position, the heat-insulating valve core 233 opens the first vent 232 to connect the cooking cavity 122 with the refrigeration cavity 2211. When the heat-insulating valve core 233 moves laterally along the first vent 232 and cuts off the first vent 232, the sealing effect is better, and thus the heat-insulating effect is also better.
- the heat-insulating valve core 233 can cut off the first vent 232 by directly blocking the first vent 232 with the heat-insulating valve core 233, or by cutting off other channels connected to the first vent 232 with the heat-insulating valve core 233, that is, the heat-insulating valve core 233 can but does not have to be in direct contact with the first vent 232.
- the movement trajectory of the heat-insulating valve core 233 refers to the trajectory formed by any point of the moving part of the heat-insulating valve core 233 during the movement process of opening and cutting off the first vent 232.
- the radial cross-section of the first air vent 232 can be various shapes. As shown in Figures 16 and 17, the radial cross-section of the first air vent 232 is circular. In addition, the radial cross-section of the first air vent 232 can also be elliptical, triangular, and various polygonal. In addition, the radial cross-section of the first air vent 232 can also be irregular, as long as it does not affect the flow of airflow.
- the heat-insulating valve core 233 has a sealing portion 2331 and a communication port 2332, and the number of the sealing portion 2331 and the communication port 2332 corresponds to the number of the first vents 232.
- the sealing portion 2331 cuts off the first vent 232;
- the communication port 2332 is aligned with the first vent 232, and the first vent 232 is opened.
- At least one end of the insulation valve core 233 may not be provided with a connecting port 2332, and only has a sealing portion 2331.
- the number of the sealing portions 2331 corresponds to the number of the first air vents 232.
- the shape of the first vent 232 is related to the movement stroke of the insulation valve core 233 and the size of the sealing portion 2331. Therefore, it is possible to shorten the size of the first vent 232 in the movement direction of the insulation valve core 233, reduce the movement stroke of the insulation valve core 233 and the size of the corresponding sealing portion 2331, and then reduce the size of the insulation valve core 233 in its movement direction, further reduce the size of the isolation valve assembly 230 in this direction, and facilitate the miniaturization design of the isolation valve assembly 230.
- the first vent 232 has a first direction c2 and a second direction c3 arranged along a radial plane.
- the first direction c2 and the second direction c3 are perpendicular to each other.
- the size of the first vent 232 in the first direction c2 is smaller than its size in the second direction c3.
- the heat-insulating valve core 233 is inserted into the first vent 232 and withdrawn from the first vent 232 from the first direction c2, and the movement trajectory of the heat-insulating valve core 233 along different angles is shown in a and a' of Figure 30.
- the size of the first vent 232 in the first direction c2 is smaller, when the heat-insulating valve core 233 cuts off the vent from the first direction c2, its movement stroke will be smaller, and the size of its sealing portion 2331 used to seal the vent in the first direction c2 will also be reduced, thereby reducing the size of the heat-insulating valve core 233 in the first direction c2.
- the first vent 232 has an elongated shape
- the first direction c2 is the width of the first vent 232
- the second direction c3 is the length of the first vent 232.
- the heat-insulating valve core 233 is inserted into the first vent 232 and withdrawn from the first vent 232 in the width direction of the elongated shape.
- FIG30 shows a first vent 232 having a narrow and long shape, that is, a waist-shaped hole.
- the narrow and long shape can also be designed in other shapes, for example, as shown in FIG31, the narrow and long shape can also be an ellipse (a), a willow leaf shape (b), a diamond shape (c), a rectangle (d) and other shapes, which cannot be listed here, but based on the deformation of these shapes (such as shapes (e) and (f) in FIG31) and other narrow and long shapes whose length in the first direction c2 is less than that in the second direction c3, this application classifies them as narrow and long shapes.
- one end of the first air vent 232 that cooperates with the insulation valve core 233 is a sealing end 2324.
- the first air vent 232 extends axially from the sealing end 2324 to the other end.
- the sealing end 2324 has a first direction c2 and a second direction c3 set along a radial plane.
- the radial cross-section of the portion of the first vent 232 away from the sealing end 2324 is larger than the radial cross-section of the sealing end 2324.

Abstract
Provided are a food ingredient cooking apparatus, and a cold and hot isolation device and an isolation valve assembly therefor. A first air ventilation opening (232) is cut off or opened by means of the movement of a heat insulation valve core (233) relative to a butt joint seat (231). A sealing end, for matching the heat insulation valve core (233), of the first air ventilation opening (232) has a first direction (c2) and a second direction (c3) which are arranged along a radial plane, the size of the first air ventilation opening (232) in the first direction (c2) is less than that of the first air ventilation opening in the second direction (c3), and a component of a motion trajectory of the heat insulation valve core (233) in the first direction (c2) is greater than zero, that is, the heat insulation valve core (233) can be switched in and switched out of the first air ventilation opening (232) in the first direction (c2) or in a direction at a certain angle relative to the first direction (c2). With respect to the first air ventilation opening (232) sealed from the second direction (c3), the size of the first air ventilation opening (232) in the first direction (c2) is relatively small, and therefore when the heat insulation valve core cuts off the first air ventilation opening (232) from the first direction (c2), the motion stroke of the heat insulation valve core is smaller, and the size of an area of the heat insulation valve core for sealing the first air ventilation opening (232) in the first direction (c2) may be also reduced.
Description
本发明涉及厨电设备,具体涉及一种食材烹饪设备的冷热隔离装置。The invention relates to kitchen electrical equipment, and in particular to a cold and hot isolation device for food cooking equipment.
目前,利用对食材加热而实现烹饪目的的食材加热烹饪设备种类很多,例如烤箱、蒸汽加热装置、微波炉以及蒸烤一体设备等。传统的食材加热烹饪设备因为不具有冷藏功能,长时间放置食材,容易导致食材营养流失、新鲜度降低,甚至腐烂,烹饪时需要用户自己将食材从冰箱拿出、解冻,然后放入到加热烹饪设备中进行加热烹饪。At present, there are many types of food heating and cooking equipment that achieve the purpose of cooking by heating food, such as ovens, steam heating devices, microwave ovens, and steam-bake-in-one equipment. Traditional food heating and cooking equipment does not have a refrigeration function. Leaving food for a long time can easily lead to loss of nutrition, reduction of freshness, and even rot. When cooking, users need to take the food out of the refrigerator, thaw it, and then put it into the heating and cooking equipment for heating and cooking.
为了能够带来更好的用户体验,也为了更方便用户的使用,现在一些食材加热烹饪设备增加了制冷模块,用来对烹饪腔内的食材制冷保鲜,因此用户可提前将食材放置到烹饪腔内,并根据需要而预设加热时间。不过,由于烹饪腔为高温区域,高温容易造成制冷模块的损坏,因此,在烹饪腔和制冷模块之间需要进行热隔离。In order to provide a better user experience and to make it more convenient for users, some food heating and cooking devices now add a refrigeration module to keep the food in the cooking cavity cool and fresh. Therefore, users can place the food in the cooking cavity in advance and preset the heating time according to their needs. However, since the cooking cavity is a high-temperature area, the high temperature can easily damage the refrigeration module. Therefore, thermal isolation is required between the cooking cavity and the refrigeration module.
但,热隔离结构中阀芯需要占据设备内部一定的空间作为活动区域,这个活动区域往往导致设备整体体积变大,因此还可进一步优化热隔离结构。However, the valve core in the thermal isolation structure needs to occupy a certain space inside the equipment as an active area. This active area often causes the overall volume of the equipment to increase. Therefore, the thermal isolation structure can be further optimized.

Of course, as the relative positions of the device and the user change, each chamber wall 121 may also have different names. In FIG14 , the cooking chamber 120 is a square structure, and in other embodiments, the cooking chamber 120 may also be other shapes, such as a spherical or elliptical structure.

为了能够对食材保鲜,该食材烹饪设备1提供了制冷组件220。该制冷组件220具有制冷仓221,该制冷仓221具有制冷腔2211,制冷组件220能够在制冷腔2211内形成冷气。在保鲜时,该冷气可通向烹饪腔122,降低烹饪腔122内的温度,从而实现对食材进行保鲜,用户可提前将食材放置到烹饪腔122内,并预约时间进行加热烹饪。In order to keep the food fresh, the food cooking device 1 is provided with a refrigeration component 220. The refrigeration component 220 has a refrigeration chamber 221, and the refrigeration chamber 221 has a refrigeration cavity 2211. The refrigeration component 220 can form cold air in the refrigeration cavity 2211. When keeping the food fresh, the cold air can flow into the cooking cavity 122 to reduce the temperature in the cooking cavity 122, thereby keeping the food fresh. The user can place the food in the cooking cavity 122 in advance and reserve a time for heating and cooking.
为了保护制冷组件220,避免加热烹饪过程中热气流进入制冷组件220而破坏其结构,本申请一些实施例中还提供来了一种隔离装置,该隔离装置除包括上述的烹饪仓120、加热组件140以及制冷组件220之外,还包括隔离阀组件230。该隔离阀组件230具有对接座231和隔热阀芯233。其中,该对接座231可为制冷仓221或烹饪仓120的一部分,如可参考图12所示示意图,直接由制冷仓221或烹饪仓120的一部分作为对接座231使用功能。或者,对接座231相对制冷仓221和/或烹饪仓120固定设置,如对接座231直接或间接安装在制冷仓221或烹饪仓120上,以实现相互之间的相对固定。该隔热阀芯233采用可耐高温的材料或结构制成,其不仅起到隔断密封效果,还同时起到隔热的效果。例如,隔热阀芯233可采用金属材料,或者还可在其内部填充隔热材料(如通常的隔热棉等)加强隔热效果。In order to protect the refrigeration assembly 220 and prevent the hot air flow from entering the refrigeration assembly 220 and damaging its structure during the heating and cooking process, some embodiments of the present application also provide an isolation device, which includes the above-mentioned cooking chamber 120, heating assembly 140 and refrigeration assembly 220, and also includes an isolation valve assembly 230. The isolation valve assembly 230 has a docking seat 231 and a heat-insulating valve core 233. Among them, the docking seat 231 can be a part of the refrigeration chamber 221 or the cooking chamber 120. For example, as shown in the schematic diagram of FIG. 12, a part of the refrigeration chamber 221 or the cooking chamber 120 is directly used as the docking seat 231. Alternatively, the docking seat 231 is fixedly arranged relative to the refrigeration chamber 221 and/or the cooking chamber 120, such as the docking seat 231 is directly or indirectly installed on the refrigeration chamber 221 or the cooking chamber 120 to achieve relative fixation between each other. The heat-insulating valve core 233 is made of a material or structure that can withstand high temperatures, which not only has a partition sealing effect, but also has a heat-insulating effect. For example, the heat-insulating valve core 233 may be made of metal material, or may be filled with heat-insulating material (such as common heat-insulating cotton, etc.) to enhance the heat-insulating effect.
请参考图6、7和14,一些实施例中,该对接座231具有至少一个贯通设置的第一通气口232。该制冷腔2211、烹饪腔122和第一通气口232连通,从而使得制冷组件220至少能够通过第一通气口232向烹饪腔122内输入冷气,用以降低烹饪腔122内的温度。即,至少一个第一通气口232为自制冷腔2211向烹饪腔122输送冷气的出气口2321,以实现冷气的输入。制冷腔2211和烹饪腔122之间可形成自制冷腔2211向烹饪腔122单向导通的冷气输入通道,烹饪腔122内的气体可通过其他的开口排出到烹饪腔122之外。请参考图6、7和14,一些实施例中,第一通气口232可分为出气口2321和进气口2322,出气口2321和进气口2322均分别与制冷腔2211和烹饪腔122连通,以形成循环风道,这种将制冷腔2211和烹饪腔122循环连通的结构,有利于防止冷气的外泄,进而提高制冷组件220对烹饪腔122的降温效率,使其更快地达到需要的低温状态或者到达更低的温度。Please refer to Figures 6, 7 and 14. In some embodiments, the docking seat 231 has at least one first vent 232 that is arranged through. The refrigeration cavity 2211, the cooking cavity 122 and the first vent 232 are connected, so that the refrigeration component 220 can at least input cold air into the cooking cavity 122 through the first vent 232 to reduce the temperature in the cooking cavity 122. That is, at least one first vent 232 is an outlet 2321 for transmitting cold air from the refrigeration cavity 2211 to the cooking cavity 122 to achieve the input of cold air. A cold air input channel that is unidirectionally connected from the refrigeration cavity 2211 to the cooking cavity 122 can be formed between the refrigeration cavity 2211 and the cooking cavity 122, and the gas in the cooking cavity 122 can be discharged to the outside of the cooking cavity 122 through other openings. Please refer to Figures 6, 7 and 14. In some embodiments, the first air vent 232 can be divided into an air outlet 2321 and an air inlet 2322. The air outlet 2321 and the air inlet 2322 are respectively connected to the refrigeration cavity 2211 and the cooking cavity 122 to form a circulating air duct. This structure that circulates the refrigeration cavity 2211 and the cooking cavity 122 is beneficial to prevent the leakage of cold air, thereby improving the cooling efficiency of the refrigeration component 220 on the cooking cavity 122, so that it can reach the required low temperature state or reach a lower temperature more quickly.
该第一通气口232两端分别与制冷腔2211和烹饪腔122直接或间接连通,控制第一通气口232的通断状态即可控制制冷腔2211和烹饪腔122的通断状态。隔热阀芯233相对的对接座231运动,在隔热阀芯233的运动轨迹上具有关闭位和打开位。请参考图11,当隔热阀芯233位于关闭位时,隔热阀芯233切断第一通气口232,以将烹饪腔122和制冷腔2211隔离;请参考图9,当隔热阀芯233位于打开位时,隔热阀芯233打开第一通气口232,以将烹饪腔122和制冷腔2211连通。当隔热阀芯233沿第一通气口232横向运动,切断第一通气口232之后,密封效果更好,进而隔热效果也更好。当然,该隔热阀芯233对第一通气口232的切断控制,可通过隔热阀芯233直接封堵第一通气口232实现,也可通过隔热阀芯233切断与第一通气口232连通的其他通道来实现,即隔热阀芯233可以但不必须与第一通气口232直接接触。其中,该隔热阀芯233的运动轨迹是指隔热阀芯233上运动部分的任一点在打开和切断第一通气口232的运动过程中所形成的轨迹。The two ends of the first vent 232 are directly or indirectly connected to the refrigeration cavity 2211 and the cooking cavity 122 respectively. The on-off state of the first vent 232 can control the on-off state of the refrigeration cavity 2211 and the cooking cavity 122. The heat-insulating valve core 233 moves relative to the docking seat 231, and has a closed position and an open position on the movement trajectory of the heat-insulating valve core 233. Please refer to Figure 11. When the heat-insulating valve core 233 is in the closed position, the heat-insulating valve core 233 cuts off the first vent 232 to isolate the cooking cavity 122 from the refrigeration cavity 2211; please refer to Figure 9. When the heat-insulating valve core 233 is in the open position, the heat-insulating valve core 233 opens the first vent 232 to connect the cooking cavity 122 with the refrigeration cavity 2211. When the heat-insulating valve core 233 moves laterally along the first vent 232 and cuts off the first vent 232, the sealing effect is better, and thus the heat-insulating effect is also better. Of course, the heat-insulating valve core 233 can cut off the first vent 232 by directly blocking the first vent 232 with the heat-insulating valve core 233, or by cutting off other channels connected to the first vent 232 with the heat-insulating valve core 233, that is, the heat-insulating valve core 233 can but does not have to be in direct contact with the first vent 232. The movement trajectory of the heat-insulating valve core 233 refers to the trajectory formed by any point of the moving part of the heat-insulating valve core 233 during the movement process of opening and cutting off the first vent 232.
进一步地,该第一通气口232的径向截面可为各种形状,如图16和17所示第一通气口232的径向截面为圆形,此外,该第一通气口232的径向截面还可为椭圆形、三角形以及各种多边形,此外,该第一通气口232的径向截面也可为异形,只要不影响气流的流动即可。Furthermore, the radial cross-section of the first air vent 232 can be various shapes. As shown in Figures 16 and 17, the radial cross-section of the first air vent 232 is circular. In addition, the radial cross-section of the first air vent 232 can also be elliptical, triangular, and various polygonal. In addition, the radial cross-section of the first air vent 232 can also be irregular, as long as it does not affect the flow of airflow.
请参考图11和17,一些实施例中,该隔热阀芯233具有密封部2331和连通口2332,密封部2331和连通口2332的数量与第一通气口232的数量对应。当隔热阀芯233位于关闭位时,密封部2331切断第一通气口232;当隔热阀芯233位于打开位时,连通口2332与第一通气口232对齐,打开第一通气口232。11 and 17 , in some embodiments, the heat-insulating valve core 233 has a sealing portion 2331 and a communication port 2332, and the number of the sealing portion 2331 and the communication port 2332 corresponds to the number of the first vents 232. When the heat-insulating valve core 233 is in the closed position, the sealing portion 2331 cuts off the first vent 232; when the heat-insulating valve core 233 is in the open position, the communication port 2332 is aligned with the first vent 232, and the first vent 232 is opened.
请参考图22和23,一些实施例中,该隔热阀芯233至少一端也可不另设连通口2332,只具有密封部2331,密封部2331的数量与第一通气口232的数量对应,当隔热阀芯233位于关闭位时,密封部2331切断第一通气口232;当隔热阀芯233位于打开位时,密封部2331从第一通气口232处移开,露出第一通气口232的至少一部分,以打开第一通气口232。Please refer to Figures 22 and 23. In some embodiments, at least one end of the insulation valve core 233 may not be provided with a connecting port 2332, and only has a sealing portion 2331. The number of the sealing portions 2331 corresponds to the number of the first air vents 232. When the insulation valve core 233 is located in the closed position, the sealing portion 2331 cuts off the first air vent 232; when the insulation valve core 233 is located in the open position, the sealing portion 2331 moves away from the first air vent 232 to expose at least a portion of the first air vent 232 to open the first air vent 232.
考虑到在切断第一通气口232时,该隔热阀芯233需要运动到能够完全遮挡住第一通气口232的位置,因此第一通气口232的形状关系着隔热阀芯233的运动行程以及密封部2331的尺寸。因此,可以考虑缩短第一通气口232在隔热阀芯233运动方向上的尺寸,而减少隔热阀芯233的运动行程以及对应密封部2331的尺寸,进而减少隔热阀芯233在其运动方向上的尺寸,进一步缩小隔离阀组件230在该方向上的尺寸,有利于隔离阀组件230的小型化设计。Considering that when the first vent 232 is cut off, the insulation valve core 233 needs to move to a position that can completely cover the first vent 232, the shape of the first vent 232 is related to the movement stroke of the insulation valve core 233 and the size of the sealing portion 2331. Therefore, it is possible to shorten the size of the first vent 232 in the movement direction of the insulation valve core 233, reduce the movement stroke of the insulation valve core 233 and the size of the corresponding sealing portion 2331, and then reduce the size of the insulation valve core 233 in its movement direction, further reduce the size of the isolation valve assembly 230 in this direction, and facilitate the miniaturization design of the isolation valve assembly 230.
请参考图30,一些实施例中,该第一通气口232具有沿径向平面设置的第一方向c2和第二方向c3,第一方向c2和第二方向c3相互垂直,第一通气口232在第一方向c2的尺寸小于其在第二方向c3的尺寸。Please refer to Figure 30. In some embodiments, the first vent 232 has a first direction c2 and a second direction c3 arranged along a radial plane. The first direction c2 and the second direction c3 are perpendicular to each other. The size of the first vent 232 in the first direction c2 is smaller than its size in the second direction c3.
该隔热阀芯233从第一方向c2上插入第一通气口232和从第一通气口232退出,隔热阀芯233沿不同角度的运动轨迹如图30的a和a’所示。相对于从第二方向c3密封通气口来说,由于第一通气口232在第一方向c2上的尺寸更小,因此当隔热阀芯233从第一方向c2切断通气口时,其运动行程将更小,而且其用来密封通气口的密封部2331在第一方向c2上的尺寸也会减少,进而隔热阀芯233在其第一方向c2上的尺寸。The heat-insulating valve core 233 is inserted into the first vent 232 and withdrawn from the first vent 232 from the first direction c2, and the movement trajectory of the heat-insulating valve core 233 along different angles is shown in a and a' of Figure 30. Compared with sealing the vent from the second direction c3, since the size of the first vent 232 in the first direction c2 is smaller, when the heat-insulating valve core 233 cuts off the vent from the first direction c2, its movement stroke will be smaller, and the size of its sealing portion 2331 used to seal the vent in the first direction c2 will also be reduced, thereby reducing the size of the heat-insulating valve core 233 in the first direction c2.
请参考图9、11、15和30,一些实施例中,一些实施例中,第一通气口232具有狭长形状,第一方向c2为第一通气口232的宽度,第二方向c3为所述第一通气口232的长度。隔热阀芯233从狭长形状的宽度方向插入第一通气口232和从第一通气口232退出。9, 11, 15 and 30, in some embodiments, the first vent 232 has an elongated shape, the first direction c2 is the width of the first vent 232, and the second direction c3 is the length of the first vent 232. The heat-insulating valve core 233 is inserted into the first vent 232 and withdrawn from the first vent 232 in the width direction of the elongated shape.
图30示出了一种第一通气口232的狭长形状,即为腰型孔状。在其他实施例中,该狭长形状还可设计其他形状,例如如图31所示,该狭长形状还可以是椭圆状(a)、柳叶形(b)、菱形(c)、长方形等(d)其他形状,在此无法穷举,但基于这些形状的变形(如图31中(e)(f)等形状)以及其他在第一方向c2的长度小于第二方向c3的狭长形状,本申请都将其归纳为狭长形状FIG30 shows a first vent 232 having a narrow and long shape, that is, a waist-shaped hole. In other embodiments, the narrow and long shape can also be designed in other shapes, for example, as shown in FIG31, the narrow and long shape can also be an ellipse (a), a willow leaf shape (b), a diamond shape (c), a rectangle (d) and other shapes, which cannot be listed here, but based on the deformation of these shapes (such as shapes (e) and (f) in FIG31) and other narrow and long shapes whose length in the first direction c2 is less than that in the second direction c3, this application classifies them as narrow and long shapes.
进一步地,请参考图9,一些实施例中,第一通气口232与隔热阀芯233配合的一端的为密封端2324,该第一通气口232沿自密封端2324沿轴向向另一端延伸,密封端2324具有沿径向平面设置的第一方向c2和第二方向c3。Further, please refer to Figure 9. In some embodiments, one end of the first air vent 232 that cooperates with the insulation valve core 233 is a sealing end 2324. The first air vent 232 extends axially from the sealing end 2324 to the other end. The sealing end 2324 has a first direction c2 and a second direction c3 set along a radial plane.
为了保证第一通气口232的气体流通量,避免因狭长形状而导致气体流通量减少,一些实施例中,请参考图9,该第一通气口232背离密封端2324的部分的径向截面大于密封端2324的径向截面。In order to ensure the gas flow rate of the first vent 232 and avoid the reduction of the gas flow rate due to the narrow and long shape, in some embodiments, please refer to Figure 9, the radial cross-section of the portion of the first vent 232 away from the sealing end 2324 is larger than the radial cross-section of the sealing end 2324.
更具体地,一些实施例中,请参考图9,第一通气口232中背离密封端2324的一端为对接端2325,对接端2325用于与烹饪腔122或制冷腔2211连通,对接端2325的径向截面为圆形。当然,其他实施例中,该对接端2325的径向截面也可以为其他形状,只要其径向截面面积大于密封端2324的径向截面面积即可。More specifically, in some embodiments, please refer to FIG9 , the end of the first vent 232 away from the sealing end 2324 is a butt end 2325, and the butt end 2325 is used to communicate with the cooking cavity 122 or the refrigeration cavity 2211, and the radial cross section of the butt end 2325 is circular. Of course, in other embodiments, the radial cross section of the butt end 2325 can also be other shapes, as long as its radial cross section area is greater than the radial cross section area of the sealing end 2324.
进一步地,一些实施例中,该隔热阀芯233以能够相对第一通气口232横向运动的方式设置,其中,请参考图12,相对第一通气口232横向是指隔热阀芯233沿第一通气口232的径向或与该径向呈一定角度切入或退出第一通气口232,图12中a以及a’分别为隔热阀芯233从不同角度相对第一通气口232横向运动的运动轨迹,以使得隔热阀芯233在第一通气口232轴向上占据更小的空间作为其运动空间,可充分利用第一通气口232周侧的横向空间,有利于在 第一通气口232轴向上减小设备的体积。Further, in some embodiments, the thermal insulation valve core 233 is arranged in a manner that it can move laterally relative to the first air vent 232, wherein, please refer to Figure 12, laterally relative to the first air vent 232 means that the thermal insulation valve core 233 cuts into or exits the first air vent 232 along the radial direction of the first air vent 232 or at a certain angle to the radial direction, and a and a' in Figure 12 are respectively movement trajectories of the thermal insulation valve core 233 moving laterally relative to the first air vent 232 from different angles, so that the thermal insulation valve core 233 occupies a smaller space in the axial direction of the first air vent 232 as its movement space, which can make full use of the lateral space around the first air vent 232, which is beneficial to reducing the volume of the equipment in the axial direction of the first air vent 232.
一些实施例中,请参考图13,该隔热阀芯233的运动轨迹在第一通气口232径向的分量大于零,即隔热阀芯233的运动轨迹的方向可分为沿第一通气口232的轴向c1延伸(即垂直于第一通气口232的径向平面,与第一通气口232的轴向c1重合或平行)的运动轨迹a1以及沿第一通气口232的径向延伸的运动轨迹a2这两个分量,图13所示实施例中,该隔热阀芯233的运动轨迹沿第一通气口232的径向延伸的分量a2大于0。在其他实施例中,当隔热阀芯233沿第一通气口232轴向运动时,此时其在第一通气口232径向的分量a2为0;当隔热阀芯233沿第一通气口232的径向运动时,其在第一通气口232的轴向c1分量a1为0。In some embodiments, please refer to FIG. 13 , the component of the motion trajectory of the insulation valve core 233 in the radial direction of the first vent 232 is greater than zero, that is, the direction of the motion trajectory of the insulation valve core 233 can be divided into two components: a motion trajectory a1 extending along the axial direction c1 of the first vent 232 (that is, perpendicular to the radial plane of the first vent 232, coincident with or parallel to the axial direction c1 of the first vent 232) and a motion trajectory a2 extending along the radial direction of the first vent 232. In the embodiment shown in FIG. 13 , the component a2 of the motion trajectory of the insulation valve core 233 extending along the radial direction of the first vent 232 is greater than 0. In other embodiments, when the insulation valve core 233 moves axially along the first vent 232, its component a2 in the radial direction of the first vent 232 is 0; when the insulation valve core 233 moves radially along the first vent 232, its component a1 in the axial direction c1 of the first vent 232 is 0.
当隔热阀芯233位于关闭位时,在第一通气口232的径向平面上,隔热阀芯233的正投影完全覆盖第一通气口232的正投影;当隔热阀芯233位于打开位时,在第一通气口232的径向平面上,隔热阀芯233的正投影至多覆盖第一通气口232的正投影的一部分,例如隔热阀芯233与第一通气口232完全错开,以便于第一通气口232可以通过露出的部分连通制冷腔2211和烹饪腔122。When the insulation valve core 233 is in the closed position, on the radial plane of the first air vent 232, the orthographic projection of the insulation valve core 233 completely covers the orthographic projection of the first air vent 232; when the insulation valve core 233 is in the open position, on the radial plane of the first air vent 232, the orthographic projection of the insulation valve core 233 at most covers a part of the orthographic projection of the first air vent 232, for example, the insulation valve core 233 is completely staggered with the first air vent 232, so that the first air vent 232 can connect the refrigeration cavity 2211 and the cooking cavity 122 through the exposed part.
请参考图12,一些实施例中,可以将隔热阀芯233相对第一通气口232横向运动进一步限定为隔热阀芯233的至少一段运动轨迹与第一通气口232的轴线c1垂直(即夹角b1为90°)或形成大于或等于45°的夹角b2。该角度的设置,可以尽量少地使隔热阀芯233在运动过程中占据第一通气口232的轴向c1空间,避免导致整个结构在第一通气口232的轴向c1上体积过大。Please refer to FIG. 12 , in some embodiments, the lateral movement of the heat-insulating valve core 233 relative to the first vent 232 can be further limited to at least one section of the movement trajectory of the heat-insulating valve core 233 being perpendicular to the axis c1 of the first vent 232 (i.e., the angle b1 is 90°) or forming an angle b2 greater than or equal to 45°. The setting of this angle can minimize the space c1 of the axial direction of the first vent 232 occupied by the heat-insulating valve core 233 during the movement, avoiding causing the entire structure to be too large in the axial direction c1 of the first vent 232.
较好地,请参考图8-11,一些实施例中,该隔热阀芯233沿第一通气口232的径向插入第一通气口232以及从第一通气口232中退出。该实施例中,只需在第一通气口232的轴向c1预留略大于隔热阀芯233厚度(即隔热阀芯233在第一通气口232轴向上的尺寸)的空间,即可满足第一隔热阀芯233在该方向上的要求,不会格外增大在该方向上的空间。当然,由于制造误差、装配误差以及具体配合结构的变化,该隔热阀芯233沿第一通气口232的径向并非必须严格地要求隔热阀芯233与第一通气口232的径向平行或重合,只要隔热阀芯233与第一通气口232的径向所成角度在一定范围内(如10°以下或20°以下),都视为沿第一通气口232的径向运动。Preferably, please refer to FIGS. 8-11 , in some embodiments, the heat-insulating valve core 233 is inserted into the first vent 232 and withdrawn from the first vent 232 along the radial direction of the first vent 232. In this embodiment, it is only necessary to reserve a space slightly larger than the thickness of the heat-insulating valve core 233 (i.e., the size of the heat-insulating valve core 233 in the axial direction of the first vent 232) in the axial direction c1 of the first vent 232, so as to meet the requirements of the first heat-insulating valve core 233 in this direction, and the space in this direction will not be increased extra. Of course, due to manufacturing errors, assembly errors and changes in specific matching structures, the heat-insulating valve core 233 does not necessarily strictly require the heat-insulating valve core 233 to be parallel or coincident with the radial direction of the first vent 232 along the radial direction of the first vent 232. As long as the angle between the heat-insulating valve core 233 and the radial direction of the first vent 232 is within a certain range (e.g., less than 10° or less than 20°), it is considered to be moving in the radial direction of the first vent 232.
进一步地,在能够实现相对第一通气口232横向移动,并切断和打开第一通气口232的前提下,该隔热阀芯233相对对接座231的运动方式可自由选择,例如,一些实施例中,该隔热阀芯233的运动为平移或旋转。其中,平移是指隔热阀芯233的运动轨迹大致位于一个平面(不限于水平面和竖直面)内,如图8-11所示,此时隔热阀芯233沿图示左右方向往复平移。当然,该平移是指隔热阀芯233的主要运动轨迹大致位于一个平面内,由于制造误差、装配误差以及具体配合结构的变化,当隔热阀芯233在平移过程中,也可以伴随一些垂直于其平移平面的浮动,本实施例将这些情况也视为平移的一种形式。隔热阀芯233的平移的轨迹可以为直线、曲线、折线、环形(即闭合路径,可以为圆环形、椭圆环形或环状多边形等)以及异形中的一个或两个以上的组合。该旋转则指隔热阀芯233以某一个为圆形进行转动,例如以其上一点为圆心自转。Further, under the premise of being able to achieve lateral movement relative to the first vent 232 and cut off and open the first vent 232, the movement mode of the heat-insulating valve core 233 relative to the docking seat 231 can be freely selected. For example, in some embodiments, the movement of the heat-insulating valve core 233 is translation or rotation. Among them, translation means that the movement trajectory of the heat-insulating valve core 233 is roughly located in a plane (not limited to the horizontal plane and the vertical plane), as shown in Figures 8-11, at this time, the heat-insulating valve core 233 reciprocates in the left and right directions shown in the figure. Of course, the translation means that the main movement trajectory of the heat-insulating valve core 233 is roughly located in a plane. Due to manufacturing errors, assembly errors and changes in specific matching structures, when the heat-insulating valve core 233 is in the translation process, it can also be accompanied by some floating perpendicular to its translation plane. This embodiment also regards these situations as a form of translation. The translation trajectory of the heat-insulating valve core 233 can be a straight line, a curve, a broken line, a ring (that is, a closed path, which can be a circular ring, an elliptical ring or a ring-shaped polygon, etc.) and a combination of one or more of two or more shapes. The rotation refers to the heat-insulating valve core 233 rotating in a certain circle, for example, rotating with a point on it as the center of the circle.
当然,该平移和旋转只是隔热阀芯233的运动方式的示例,在其他实施例中,还可选择其他的运动方式。Of course, the translation and rotation are only examples of the movement modes of the thermal insulation valve core 233. In other embodiments, other movement modes may also be selected.
进一步地,一些实施例中,请参考图9、17和23,一些实施例中,该对接座231具有支撑面2313,隔热阀芯233沿支撑面2313的表面运动。例如,隔热阀芯233以能够在支撑面2313上平移或旋转的方式设置。该第一通气口232贯通设置在支撑面2313上,隔热阀芯233在运动过程中可与接触或不接触支撑面2313。该方式可减少隔热阀芯233在垂直于支撑面2313方向上所占空间,可充分利用支撑面2313本身横向空间,有利于在垂直于支撑面2313的方向上减小设备的体积。Further, in some embodiments, please refer to Figures 9, 17 and 23. In some embodiments, the docking seat 231 has a support surface 2313, and the insulation valve core 233 moves along the surface of the support surface 2313. For example, the insulation valve core 233 is arranged in a manner that can translate or rotate on the support surface 2313. The first vent 232 is arranged through the support surface 2313, and the insulation valve core 233 may or may not contact the support surface 2313 during the movement. This method can reduce the space occupied by the insulation valve core 233 in the direction perpendicular to the support surface 2313, and can make full use of the lateral space of the support surface 2313 itself, which is conducive to reducing the volume of the device in the direction perpendicular to the support surface 2313.
进一步地,一些实施例中,仓壁121具有用于安装隔离阀组件230的对接外壁,隔离阀组件230位于对接外壁的外侧,第一通气口232的轴线c1与对接外壁所在平面垂直或形成锐角,如此,在具备冷却保鲜功能的同时,还可减少整个设备在对接外壁这一侧于第一通气口232轴 向上的体积。其中,只要不与其他结构冲突,该仓壁121的任一侧都可作为对接外壁,例如背侧壁124、左侧壁125、右侧壁126、顶壁128和底壁127中的至少一侧具有对接外壁。Furthermore, in some embodiments, the warehouse wall 121 has a docking outer wall for installing the isolation valve assembly 230, the isolation valve assembly 230 is located outside the docking outer wall, and the axis c1 of the first vent 232 is perpendicular to or forms an acute angle with the plane where the docking outer wall is located, so that while having the cooling and fresh-keeping function, the volume of the entire device on the docking outer wall side in the axial direction of the first vent 232 can be reduced. Among them, as long as it does not conflict with other structures, any side of the warehouse wall 121 can be used as a docking outer wall, for example, at least one side of the back wall 124, the left wall 125, the right wall 126, the top wall 128 and the bottom wall 127 has a docking outer wall.
请参考图14,一些实施例中,该左侧壁125具有对接外壁129,即制冷组件220设置于左侧壁125上,在图示实施例中,该第一通气口232的轴线c1与左侧壁125相互垂直,当然,两者也可成锐角结构。其中,请参考图5和14,一些实施例中,制冷组件220通过对接座231与烹饪仓120对接。为了起到良好的隔热作用,一些实施例中,该对接座231与烹饪仓120之间设置隔热层235(如隔热棉等隔热材料制成)进行隔热。Please refer to FIG. 14. In some embodiments, the left side wall 125 has a docking outer wall 129, that is, the refrigeration component 220 is arranged on the left side wall 125. In the illustrated embodiment, the axis c1 of the first vent 232 is perpendicular to the left side wall 125. Of course, the two can also form an acute angle structure. Please refer to FIGS. 5 and 14. In some embodiments, the refrigeration component 220 is docked with the cooking chamber 120 through the docking seat 231. In order to achieve a good heat insulation effect, in some embodiments, a heat insulation layer 235 (such as made of heat insulation materials such as heat insulation cotton) is arranged between the docking seat 231 and the cooking chamber 120 for heat insulation.
进一步地,请参考图8,一些实施例中,为了进一步地增加制冷组件220与烹饪仓120的隔热效果,对接座231上填充有第二隔热层236(如隔热棉等隔热材料制成),通过第二隔热层236进行隔热。Further, please refer to Figure 8. In some embodiments, in order to further increase the insulation effect of the refrigeration component 220 and the cooking chamber 120, the docking seat 231 is filled with a second insulation layer 236 (made of insulation materials such as insulation cotton), and insulation is performed by the second insulation layer 236.
此外,在其他一些实施例中,该左侧壁125和右侧壁126中的至少一侧具有对接外壁129,相对于其他制冷组件220与左侧壁125和右侧壁126的安装方式而言,这种布置将使得整个设备左右方向(本实施例将其定义为设备的宽度方向)上的尺寸更小。此时,隔热阀芯233可沿对接外壁129的前后方向或上下方向相对对接座231运动。本实施例将食材取放口123所在一侧定义为前,背侧壁124所在一侧为后,左侧壁125所在一侧为左,右侧壁126所在一侧为右,顶壁128所在一侧为上,底壁127所在一侧为下。这些方位名词只是为了更清楚的说明各特征之间的相对位置关系,其实质在于强调各特征的相对位置,因此各方位名词可随着方向定义的不同而有不同的名称。In addition, in some other embodiments, at least one side of the left side wall 125 and the right side wall 126 has a docking outer wall 129. Compared with the installation method of other refrigeration components 220 and the left side wall 125 and the right side wall 126, this arrangement will make the size of the entire device in the left and right direction (defined as the width direction of the device in this embodiment) smaller. At this time, the insulation valve core 233 can move relative to the docking seat 231 along the front-to-back direction or the up-down direction of the docking outer wall 129. In this embodiment, the side where the food access port 123 is located is defined as the front, the side where the back wall 124 is located is the back, the side where the left side wall 125 is located is the left, the side where the right side wall 126 is located is the right, the side where the top wall 128 is located is the top, and the side where the bottom wall 127 is located is the bottom. These directional nouns are only for more clearly explaining the relative position relationship between the various features. Their essence is to emphasize the relative position of each feature. Therefore, each directional noun can have different names depending on the different direction definitions.
进一步地,为了控制隔热阀芯233的运动,该隔离阀组件230具有驱动件234,驱动件234与隔热阀芯233连接,用以驱动隔热阀芯233在关闭位和打开位之间运动。其中,该驱动件234可以为电控驱动件,即由用户输入电信号指令或者由设备系统自动输出控制信号,以控制该电控驱动件的工作状态,例如电控驱动件可采用旋转电机、直线电机、气缸、液缸、电磁铁驱动件等现有的电控驱动件。和/或,该驱动件234也可为手动驱动件,即通过机械传动结构,由用户手动输入力信号,以驱动隔热阀芯233的运动,例如手动驱动件可为手柄、推拉杆、转盘等采用的机械控制结构。Furthermore, in order to control the movement of the heat-insulating valve core 233, the isolation valve assembly 230 has a driving member 234, which is connected to the heat-insulating valve core 233 to drive the heat-insulating valve core 233 to move between the closed position and the open position. The driving member 234 can be an electric control driving member, that is, the user inputs an electric signal instruction or the device system automatically outputs a control signal to control the working state of the electric control driving member. For example, the electric control driving member can adopt existing electric control driving members such as rotary motors, linear motors, cylinders, hydraulic cylinders, and electromagnet driving members. And/or, the driving member 234 can also be a manual driving member, that is, through a mechanical transmission structure, the user manually inputs a force signal to drive the movement of the heat-insulating valve core 233. For example, the manual driving member can be a mechanical control structure adopted by a handle, a push-pull rod, a turntable, etc.
请参考图8-11以及图15,一些实施例中,该驱动件234采用电机进行驱动,以提高对阀芯控制的便利性。该驱动件234可直接与隔热阀芯233连接,以实现联动。当然,隔离阀组件230也具有传动机构,驱动件234的输出端与传动机构连接,用以驱动传动机构运动,传动机构与隔热阀芯233之间活动连接,以带动隔热阀芯233运动。Please refer to Figures 8-11 and 15. In some embodiments, the driving member 234 is driven by a motor to improve the convenience of controlling the valve core. The driving member 234 can be directly connected to the thermal insulation valve core 233 to achieve linkage. Of course, the isolation valve assembly 230 also has a transmission mechanism, and the output end of the driving member 234 is connected to the transmission mechanism to drive the transmission mechanism to move. The transmission mechanism and the thermal insulation valve core 233 are movably connected to drive the thermal insulation valve core 233 to move.
进一步地,由于烹饪仓120在进行食材烹饪时处于高温环境,温度通常会自烹饪仓120传递到四周,也会一定程度的传递到隔热阀芯233和驱动件234上。当驱动件234为手动驱动件时,可能把热量传递到用户握持部,如果温度过高,将影响用户的操控体验。当驱动件234为电控驱动件时,过高的环境温度也不利于电控驱动件的工作效率,还可能降低其使用寿命。因此,一些实施例中,还可利用制冷仓221的冷却效果附带给驱动件234以及隔热阀芯233降温。Furthermore, since the cooking chamber 120 is in a high temperature environment when cooking ingredients, the temperature is usually transferred from the cooking chamber 120 to the surroundings, and will also be transferred to the insulation valve core 233 and the driver 234 to a certain extent. When the driver 234 is a manual driver, the heat may be transferred to the user's grip. If the temperature is too high, it will affect the user's control experience. When the driver 234 is an electrically controlled driver, excessively high ambient temperature is not conducive to the working efficiency of the electrically controlled driver, and may also reduce its service life. Therefore, in some embodiments, the cooling effect of the refrigeration chamber 221 can also be used to cool the driver 234 and the insulation valve core 233.
请参考图6、7和18,一些实施例中,该隔热阀芯233和驱动件234设于制冷仓221的内侧,制冷腔2211内的冷气能够对隔离阀组件230降温。其中,该实施例中,该对接座231为制冷仓221的一部分,该第一通气口232直接设于制冷仓221的仓壁121上。当然,在其他实施例中,该对接座231也可固定安装在制冷仓221上,不作为制冷仓221的一部分。Please refer to Figures 6, 7 and 18. In some embodiments, the heat-insulating valve core 233 and the driving member 234 are arranged on the inner side of the refrigeration chamber 221, and the cold air in the refrigeration cavity 2211 can cool down the isolation valve assembly 230. In this embodiment, the docking seat 231 is a part of the refrigeration chamber 221, and the first vent 232 is directly arranged on the chamber wall 121 of the refrigeration chamber 221. Of course, in other embodiments, the docking seat 231 can also be fixedly installed on the refrigeration chamber 221 and is not a part of the refrigeration chamber 221.
进一步地,请参考图6、7和图18和19,一些实施例中,该制冷仓221具有基座2214和盖体231(这些实施例中该对接座231作为盖体231),基座2214和盖体231固定并围合成制冷腔2211,这包括直接由基座2214和盖体231围成制冷腔2211,也包括基座2214和盖体231与其他部件一起围成制冷腔2211。其中,该基座2214和盖体231均可以为一体成型的结构,也可分别由多个子部件拼接组装而成。Further, please refer to Figures 6, 7 and Figures 18 and 19. In some embodiments, the refrigeration bin 221 has a base 2214 and a cover 231 (in these embodiments, the docking seat 231 serves as the cover 231), and the base 2214 and the cover 231 are fixed and enclosed to form a refrigeration cavity 2211, which includes directly enclosing the refrigeration cavity 2211 by the base 2214 and the cover 231, and also includes the base 2214 and the cover 231 together with other components to enclose the refrigeration cavity 2211. Among them, the base 2214 and the cover 231 can both be an integrally formed structure, and can also be assembled by splicing multiple sub-components.
具体地,作为一种示例,请参考图6、7和图18和19,一些实施例中,该盖体231具有朝向基座2214凸起设置的凸壳2314,该基座2214上具有与凸壳2314配合的配合部2215,在图示实施例中,该配合部2215可以为凹槽形式,以便凸壳2314能够嵌入至配合部2215中,以形成定位。基座2214和盖体231之间可通过螺钉固定、焊接、粘接、卡接等。该实施例中,盖体 231的至少一部分作为对接座231,隔热阀芯233沿盖体231的内表面运动,例如平移或者转动。当然,对接座231也可相对盖体231固定设置。Specifically, as an example, please refer to Figures 6, 7 and Figures 18 and 19. In some embodiments, the cover 231 has a convex shell 2314 protruding toward the base 2214, and the base 2214 has a matching portion 2215 that matches the convex shell 2314. In the illustrated embodiment, the matching portion 2215 can be in the form of a groove so that the convex shell 2314 can be embedded in the matching portion 2215 to form a positioning. The base 2214 and the cover 231 can be fixed by screws, welding, bonding, clamping, etc. In this embodiment, at least a part of the cover 231 serves as a docking seat 231, and the insulation valve core 233 moves along the inner surface of the cover 231, such as translation or rotation. Of course, the docking seat 231 can also be fixed relative to the cover 231.
进一步地,请继续参考图6、7和图18和19,一些实施例中,还包括隔层板2216,隔层板2216设于基座2214和盖体231之间,隔层板2216与基座2214形成第一制冷腔2212,制冷组件220具有制冷件222,该制冷件222的冷却部2221至少一部分设于第一制冷腔2212内。该第一制冷腔2212可与出气口2321连通,以便引导冷气从出气口2321排出。该第一制冷腔2212也可与进气口2322连通,以便来自外界或烹饪腔122的气体能够进入到第一制冷腔2212中。Further, please continue to refer to Figures 6, 7, 18 and 19. In some embodiments, an interlayer plate 2216 is further included. The interlayer plate 2216 is disposed between the base 2214 and the cover 231. The interlayer plate 2216 and the base 2214 form a first refrigeration cavity 2212. The refrigeration assembly 220 has a refrigeration element 222. At least a portion of the cooling portion 2221 of the refrigeration element 222 is disposed in the first refrigeration cavity 2212. The first refrigeration cavity 2212 can be communicated with the air outlet 2321 to guide the cold air to be discharged from the air outlet 2321. The first refrigeration cavity 2212 can also be communicated with the air inlet 2322 so that the gas from the outside or the cooking cavity 122 can enter the first refrigeration cavity 2212.
该制冷件222的冷却部2221至少部分位于第一制冷腔2212内,该冷却部2221既可以包括制冷件222的制冷端,当制冷端上设有导温结构时,该冷却部2221还包括该导温结构。例如,请参考图6、7和图18-20,一些实施例中,该制冷件222为半导体制冷片,该半导体制冷片具有制冷端和热端,该冷却部2221包括制冷端和与制冷端连接的导温翅片,该导温翅片至少部分位于第一制冷腔2212内。冷却部2221产生低温通过导温翅片传递至第一制冷腔2212内的空气,以形成冷气。The cooling part 2221 of the refrigeration element 222 is at least partially located in the first refrigeration cavity 2212. The cooling part 2221 may include the refrigeration end of the refrigeration element 222. When a heat transfer structure is provided on the refrigeration end, the cooling part 2221 also includes the heat transfer structure. For example, referring to Figures 6, 7 and 18-20, in some embodiments, the refrigeration element 222 is a semiconductor refrigeration plate, which has a refrigeration end and a hot end. The cooling part 2221 includes the refrigeration end and a heat transfer fin connected to the refrigeration end, and the heat transfer fin is at least partially located in the first refrigeration cavity 2212. The low temperature generated by the cooling part 2221 is transferred to the air in the first refrigeration cavity 2212 through the heat transfer fin to form cold air.
其中,请参考图6、7和图18-20,一些实施例中,该第一制冷腔2212内还可以设有第一流体驱动件223,该第一流体驱动件223用于驱动气体流经冷却部2221,并向出气口2321流动,以提高冷气的排出量,增加制冷效率。在图示实施例中,该第一流体驱动件223为离心风扇,当然在其他实施例中也可替换为其他形式的流体驱动件234。该离心风扇为径向出风,其可沿进气口2322的轴向设置,并与冷却部2221并排,从而减小了整个第一制冷腔2212在进气口2322和出口气轴向的空间要求,有利于在该方向上减小尺寸。Wherein, please refer to Figures 6, 7 and Figures 18-20. In some embodiments, a first fluid driving member 223 may be further provided in the first refrigeration chamber 2212. The first fluid driving member 223 is used to drive the gas to flow through the cooling portion 2221 and flow toward the air outlet 2321 to increase the discharge amount of cold air and increase the refrigeration efficiency. In the illustrated embodiment, the first fluid driving member 223 is a centrifugal fan, which may be replaced by other forms of fluid driving members 234 in other embodiments. The centrifugal fan is radially discharged, which may be arranged along the axial direction of the air inlet 2322 and arranged side by side with the cooling portion 2221, thereby reducing the space requirement of the entire first refrigeration chamber 2212 in the axial direction of the air inlet 2322 and the outlet gas, which is conducive to reducing the size in this direction.
进一步地,该隔层板2216还与盖体231围成用于第二制冷腔2213,第二制冷腔2213与第一制冷腔2212相通或隔开,隔热阀芯233和驱动件234设于第二制冷腔2213中。在图6、7和图18和19所示的实施例中,该第一制冷腔2212和第二制冷腔2213连通,例如可通过隔层板2216与基座2214之间的缝隙连通,使部分冷气可以流动到第二制冷腔2213内,从而降低第二制冷腔2213内的温度,进而对隔热阀芯233、驱动件234以及对接座231(或盖体231)进行降温。Furthermore, the interlayer plate 2216 and the cover body 231 also enclose a second refrigeration chamber 2213, the second refrigeration chamber 2213 is communicated with or separated from the first refrigeration chamber 2212, and the heat-insulating valve core 233 and the driving member 234 are arranged in the second refrigeration chamber 2213. In the embodiments shown in Figures 6, 7 and Figures 18 and 19, the first refrigeration chamber 2212 and the second refrigeration chamber 2213 are communicated, for example, through the gap between the interlayer plate 2216 and the base 2214, so that part of the cold air can flow into the second refrigeration chamber 2213, thereby reducing the temperature in the second refrigeration chamber 2213, and then cooling the heat-insulating valve core 233, the driving member 234 and the docking seat 231 (or the cover body 231).
当然,在另一些实施例中,该第一制冷腔2212和第二制冷腔2213也可密封隔开,两者不相通,以保证第一制冷腔2212内的冷气可以尽可能多地输送至烹饪腔122内,提高制冷降温效率。此时,虽然第一制冷腔2212和第二制冷腔2213不相通,但第一制冷腔2212内的冷气依然可通过隔层板2216本身而传递至第二制冷腔2213中,进而一定程度地降低第二制冷腔2213内的温度,用作对隔热阀芯233、驱动件234以及对接座231(或盖体231)进行降温。Of course, in other embodiments, the first refrigeration cavity 2212 and the second refrigeration cavity 2213 may also be sealed and separated, and the two are not connected, so as to ensure that the cold air in the first refrigeration cavity 2212 can be transported to the cooking cavity 122 as much as possible, thereby improving the refrigeration and cooling efficiency. At this time, although the first refrigeration cavity 2212 and the second refrigeration cavity 2213 are not connected, the cold air in the first refrigeration cavity 2212 can still be transferred to the second refrigeration cavity 2213 through the interlayer plate 2216 itself, thereby reducing the temperature in the second refrigeration cavity 2213 to a certain extent, and is used to cool the heat insulation valve core 233, the driving member 234 and the docking seat 231 (or the cover body 231).
将制冷腔2211分为第一制冷腔2212和第二制冷腔2213,不仅可以使冷气输送更加独立,而且还可以利用冷气的低温来对隔热阀芯233、驱动件234以及对接座231(或盖体231)进行降温,同时也利于整个制冷组件220结构的紧凑,有利于体积的减小。Dividing the refrigeration chamber 2211 into a first refrigeration chamber 2212 and a second refrigeration chamber 2213 can not only make the cold air delivery more independent, but also utilize the low temperature of the cold air to cool the insulation valve core 233, the driving member 234 and the docking seat 231 (or the cover body 231), while also facilitating the compactness of the structure of the entire refrigeration assembly 220 and reducing its volume.
为了能够进一步地减小体积,请继续参考图6、7和图18-20,一些实施例中,隔层板2216具有向第一制冷腔2212内部凹陷的凹陷槽2219,该凹陷槽2219用于收纳驱动件234。一些实施例中,该凹陷槽2219向第一制冷腔2212内凸起设置,使其伸入第一制冷腔2212内,从而利用第一制冷腔2212内的冷气,对驱动件234进行降温。例如,在图示实施例中,该凹陷槽2219向第一制冷腔2212凸起设置于位于冷却部2221的中间或位于相邻冷却部2221之间的间隙内。而且,该凹陷槽2219向第一制冷腔2212凸起设置,也可充分利用第一制冷腔2212内的空间来容置驱动件234,因此在出气口2321的轴向上不必另外设置过大的空间来容纳驱动件234,进一步地减小制冷组件220在出气口2321轴向c1上的尺寸,更利于制冷组件220在该方向上实现轻薄化。In order to further reduce the volume, please continue to refer to Figures 6, 7 and 18-20. In some embodiments, the interlayer plate 2216 has a recessed groove 2219 recessed into the first refrigeration cavity 2212, and the recessed groove 2219 is used to accommodate the driving member 234. In some embodiments, the recessed groove 2219 is protruded into the first refrigeration cavity 2212 so as to extend into the first refrigeration cavity 2212, thereby using the cold air in the first refrigeration cavity 2212 to cool the driving member 234. For example, in the illustrated embodiment, the recessed groove 2219 is protruded toward the first refrigeration cavity 2212 and is located in the middle of the cooling portion 2221 or in the gap between adjacent cooling portions 2221. Moreover, the recessed groove 2219 is arranged to protrude toward the first refrigeration cavity 2212, and the space in the first refrigeration cavity 2212 can be fully utilized to accommodate the driving member 234. Therefore, there is no need to set up an excessively large space in the axial direction of the air outlet 2321 to accommodate the driving member 234, which further reduces the size of the refrigeration component 220 in the axial direction c1 of the air outlet 2321, and is more conducive to the refrigeration component 220 to be thin and light in this direction.
为了将第一制冷腔2212与第一通气口232连通,请继续参考图18,一些实施例中,隔层板2216上设有第二通气口2219,第二通气口2219与对应的第一通气口232相通,以实现气体的通过。该第二通气口2219与对应的第一通气口232可直接对接连通,也可通过其他转接结构实现连通。In order to connect the first refrigeration cavity 2212 with the first vent 232, please continue to refer to FIG. 18. In some embodiments, the interlayer plate 2216 is provided with a second vent 2219, and the second vent 2219 is connected with the corresponding first vent 232 to achieve the passage of gas. The second vent 2219 and the corresponding first vent 232 can be directly connected or connected through other transfer structures.
请继续参考图6、7和图18-20,一些实施例中,针对第一通气口232的数量和类型,该第 二通气口2219同样可分为第二进气口2218和第二出气口2217,该第二进气口2218与对接座231的进气口2322连通,该第二出气口2217与对接座231的出气口2321连通。当然,当对接座231只有出气口2321时,该第二通气口2219也可只具有第二出气口2217,并与对接座231的出气口2321连通。Please continue to refer to Figures 6, 7 and 18-20. In some embodiments, according to the number and type of the first vents 232, the second vent 2219 can also be divided into a second air inlet 2218 and a second air outlet 2217. The second air inlet 2218 is connected to the air inlet 2322 of the docking seat 231, and the second air outlet 2217 is connected to the air outlet 2321 of the docking seat 231. Of course, when the docking seat 231 has only the air outlet 2321, the second vent 2219 can also have only the second air outlet 2217 and be connected to the air outlet 2321 of the docking seat 231.
请继续参考图6、9,一些实施例中,该第二通气口2219和第一通气口232之间可具有阀芯运动间隙237,隔热阀芯233在阀芯运动间隙237内运动,用以切断和打开第一通气口232与对应的第二通气口2219之间的通道。Please continue to refer to Figures 6 and 9. In some embodiments, there may be a valve core movement gap 237 between the second air vent 2219 and the first air vent 232. The insulation valve core 233 moves in the valve core movement gap 237 to cut off and open the channel between the first air vent 232 and the corresponding second air vent 2219.
当然,在其他一些实施例中,制冷腔2211还可被分隔成更多的子制冷腔,每个子制冷腔用来容置不同的部件和结构。或者,在另外一些实施例中,该制冷腔2211也可不分隔为多个子制冷腔,即制冷腔2211为一个连通的腔体,例如,将图6、7和图20中的第一制冷腔2212封闭,作为一个独立的制冷腔2211使用,此时,该隔离阀组件230可被设置在第一制冷腔2212内,也可按照现在的结构,安装在隔层板2216上,此时隔层板2216作为制冷仓221的仓壁121。Of course, in some other embodiments, the refrigeration cavity 2211 may be further divided into more sub-refrigeration cavities, each of which is used to accommodate different components and structures. Alternatively, in some other embodiments, the refrigeration cavity 2211 may not be divided into multiple sub-refrigeration cavities, that is, the refrigeration cavity 2211 is a connected cavity. For example, the first refrigeration cavity 2212 in Figures 6, 7 and 20 is closed and used as an independent refrigeration cavity 2211. In this case, the isolation valve assembly 230 may be set in the first refrigeration cavity 2212, or it may be installed on the interlayer plate 2216 according to the current structure. In this case, the interlayer plate 2216 serves as the warehouse wall 121 of the refrigeration warehouse 221.
以上示出了一些将隔离阀组件230设于制冷仓221内的实施例,此外,隔离阀组件230还可设于制冷仓221的外侧,请参考图21,一些实施例中。隔热阀芯233和驱动件234设于制冷仓221的外侧,对接座231为制冷仓221的一部分或固定在制冷仓221上。The above shows some embodiments in which the isolation valve assembly 230 is arranged in the refrigeration bin 221. In addition, the isolation valve assembly 230 can also be arranged outside the refrigeration bin 221. Please refer to FIG. 21 for some embodiments. The heat insulation valve core 233 and the driving member 234 are arranged outside the refrigeration bin 221, and the docking seat 231 is a part of the refrigeration bin 221 or is fixed on the refrigeration bin 221.
当隔离阀组件230设于制冷仓221外侧时,一些实施例中,该制冷仓221面向驱动件234的一面也可具有凹陷槽2219,凹陷槽2219自烹饪腔122所在一侧向制冷腔2211的内部凹陷,驱动件234嵌设于凹陷槽2219内。其中,凹陷槽2219的背面向制冷腔2211内凸起,用以通过制冷腔2211内的冷气对驱动件234进行降温,同时也可利用制冷腔2211的空间容置驱动件234,提高结构的紧凑性,减小通气口轴向的尺寸。When the isolation valve assembly 230 is disposed outside the refrigeration chamber 221, in some embodiments, the side of the refrigeration chamber 221 facing the driver 234 may also have a recessed groove 2219, the recessed groove 2219 is recessed from the side where the cooking cavity 122 is located toward the inside of the refrigeration cavity 2211, and the driver 234 is embedded in the recessed groove 2219. The back side of the recessed groove 2219 protrudes toward the inside of the refrigeration cavity 2211, so as to cool the driver 234 through the cold air in the refrigeration cavity 2211, and at the same time, the space of the refrigeration cavity 2211 can be used to accommodate the driver 234, thereby improving the compactness of the structure and reducing the axial size of the vent.
进一步地,该第一通气口232可直接与烹饪仓120连通,也可通过过渡结构与烹饪仓120实现连通。请参考图5和14,一些实施例中,该第一通气口232直接插入至烹饪仓120的烹饪腔122内。第一通气口232插入烹饪腔122的一端可设置滤网2323,以防止食材残渣进入到第一通气口232内。当然,在其他实施例中,该第一通气口232也可与烹饪仓120上的对接口对接,或者由烹饪仓120上的对接口插入第一通气口232中。Furthermore, the first vent 232 may be directly connected to the cooking chamber 120, or may be connected to the cooking chamber 120 through a transition structure. Referring to FIGS. 5 and 14 , in some embodiments, the first vent 232 is directly inserted into the cooking cavity 122 of the cooking chamber 120. A filter 2323 may be provided at one end of the first vent 232 inserted into the cooking cavity 122 to prevent food residue from entering the first vent 232. Of course, in other embodiments, the first vent 232 may also be connected to the docking port on the cooking chamber 120, or may be inserted into the first vent 232 through the docking port on the cooking chamber 120.
请参考图16和17,一些实施例中,该对接座231本身可以为一体成型结构,例如一体成型的金属或其他材料制成。该第一通气口232可贯通的设置在该一体成型的结构上。此外,该对接座231也可以由多个零件装配组合而成,请参考图8-11,一些实施例中,该对接座231包括座体2311和设置在座体2311上的对接头2312,该第一通气口232贯通设置在对接头2312上。根据第一通气口232数量和类型的不同,该对接头2312可以为一个或多个。该对接座231可通过该对接头2312与烹饪仓120连通,如图5和14所示,对接头2312的一端直接插入到烹饪仓120内,对接头2312的另一端则用来直接或间接地连通制冷腔2211。Please refer to Figures 16 and 17. In some embodiments, the docking seat 231 itself can be an integrally formed structure, such as an integrally formed metal or other material. The first vent 232 can be set through the integrally formed structure. In addition, the docking seat 231 can also be assembled and combined by multiple parts. Please refer to Figures 8-11. In some embodiments, the docking seat 231 includes a seat body 2311 and a docking head 2312 set on the seat body 2311, and the first vent 232 is set through the docking head 2312. Depending on the number and type of the first vent 232, the docking head 2312 can be one or more. The docking seat 231 can be connected to the cooking chamber 120 through the docking head 2312. As shown in Figures 5 and 14, one end of the docking head 2312 is directly inserted into the cooking chamber 120, and the other end of the docking head 2312 is used to directly or indirectly connect to the refrigeration chamber 2211.
进一步地,请参考图8-11、图16和17以及图22-29,一些实施例中,第一通气口232可分为出气口2321和进气口2322,此时,利用同一个驱动件234控制隔热阀芯233同步打开和关闭进气口2322和出气口2321。具体地,当隔热阀芯233位于关闭位时,隔热阀芯233同时切断出气口2321和进气口2322;当隔热阀芯233位于打开位时,隔热阀芯233同时打开出气口2321和进气口2322。这种利用同一个驱动件234控制隔热阀芯233同步打开和关闭进气口2322和出气口2321的方式,能够节省驱动件234的数量,从而简化结构,有利于将结构设计的更紧凑,体积更小。Further, please refer to Figures 8-11, 16 and 17, and 22-29. In some embodiments, the first vent 232 can be divided into an outlet 2321 and an inlet 2322. At this time, the same driver 234 is used to control the heat-insulating valve core 233 to synchronously open and close the inlet 2322 and the outlet 2321. Specifically, when the heat-insulating valve core 233 is in the closed position, the heat-insulating valve core 233 simultaneously cuts off the outlet 2321 and the inlet 2322; when the heat-insulating valve core 233 is in the open position, the heat-insulating valve core 233 simultaneously opens the outlet 2321 and the inlet 2322. This method of using the same driver 234 to control the heat-insulating valve core 233 to synchronously open and close the inlet 2322 and the outlet 2321 can save the number of drivers 234, thereby simplifying the structure, which is conducive to making the structure more compact and smaller in size.
当然,在其他一些实施例中,也可针对出气口2321和进气口2322分别设置不同的驱动件234和隔热阀芯233进行通断控制。Of course, in some other embodiments, different driving members 234 and heat-insulating valve cores 233 may be respectively provided for the air outlet 2321 and the air inlet 2322 to perform on-off control.
进一步地,对接座231可以为一个或多个,当第一通气口232具有多个时,这些第一通气口232可设置在同一个对接座231上,也可设于不同的对接座231上。例如,如图8-11、图16和17以及图28和29所示实施例,作为第一通气口232的进气口2322和出气口2321可设置在同一个对接座231上。再例如,如图22-27所示,作为第一通气口232的进气口2322和出气口2321可分别设置在不同的对接座231上。Further, the docking seat 231 may be one or more. When there are multiple first vents 232, these first vents 232 may be arranged on the same docking seat 231 or on different docking seats 231. For example, as shown in the embodiments of FIGS. 8-11, 16 and 17, and 28 and 29, the air inlet 2322 and the air outlet 2321 as the first vent 232 may be arranged on the same docking seat 231. For another example, as shown in FIGS. 22-27, the air inlet 2322 and the air outlet 2321 as the first vent 232 may be arranged on different docking seats 231, respectively.
具体地,请参考图8-11、图16和17以及图28和29,一些实施例中,该对接座231为一个, 该对接座231可同时具有至少两个第一通气口232,第一通气口232分为出气口2321和进气口2322,驱动件234安装在对接座231上,并位于出气口2321和进气口2322之间的区域,充分利用出气口2321和进气口2322之间的区域。Specifically, please refer to Figures 8-11, Figures 16 and 17, and Figures 28 and 29. In some embodiments, the docking seat 231 is one, and the docking seat 231 can have at least two first air vents 232 at the same time. The first air vents 232 are divided into an air outlet 2321 and an air inlet 2322. The driving member 234 is installed on the docking seat 231 and is located in the area between the air outlet 2321 and the air inlet 2322, so as to make full use of the area between the air outlet 2321 and the air inlet 2322.
请参考图8-11、图16和17,一些实施例中,该驱动件234为电机,具体可以为旋转电机。该传动机构为丝杆螺母传动副,电机与丝杆螺母传动副的丝杆2381连接,该电机输出旋转运动,以带动丝杆2381旋转,进而传动螺母2382沿丝杆2381轴向往复运动,丝杆螺母传动副的螺母2382与隔热阀芯233连接,以带动隔热阀芯233沿丝杆2381的轴向往复运动,实现隔热阀芯233在打开位和关闭位之间的切换。这种传动方式简单稳定,有利于整个结构体积的简化,也便于实现隔热阀芯233对进气口2322和出气口2321的控制。Please refer to Figures 8-11, 16 and 17. In some embodiments, the driving member 234 is a motor, specifically a rotary motor. The transmission mechanism is a screw-nut transmission pair, and the motor is connected to the screw 2381 of the screw-nut transmission pair. The motor outputs a rotational motion to drive the screw 2381 to rotate, and then the transmission nut 2382 reciprocates along the axial direction of the screw 2381. The nut 2382 of the screw-nut transmission pair is connected to the thermal insulation valve core 233 to drive the thermal insulation valve core 233 to reciprocate along the axial direction of the screw 2381, so as to realize the switching of the thermal insulation valve core 233 between the open position and the closed position. This transmission method is simple and stable, which is conducive to the simplification of the entire structural volume, and is also convenient for realizing the control of the thermal insulation valve core 233 on the air inlet 2322 and the air outlet 2321.
请参考图24-27,一些实施例中,该驱动件234为电机,具体可以为旋转电机。传动机构为齿轮齿条机构,电机与齿轮齿条机构的驱动齿轮2384连接,齿轮齿条机构具有至少一条齿条2385,驱动齿轮2384与齿条2385啮合,隔热阀芯233与对应的齿条2385形成隔热阀芯233联动结构,齿条2385带动隔热阀芯233在关闭位和打开位之间切换。Please refer to Figures 24-27. In some embodiments, the driving member 234 is a motor, specifically a rotary motor. The transmission mechanism is a rack-and-pinion mechanism. The motor is connected to a driving gear 2384 of the rack-and-pinion mechanism. The rack-and-pinion mechanism has at least one rack 2385. The driving gear 2384 is meshed with the rack 2385. The heat-insulating valve core 233 and the corresponding rack 2385 form a linkage structure of the heat-insulating valve core 233. The rack 2385 drives the heat-insulating valve core 233 to switch between the closed position and the open position.
当第一通气口232分为进气口2322和出气口2321时,请参考图24-27,一些实施例中,驱动齿轮2384的轴线平行于第一通气口232的轴线c1。齿条2385为两个,两个齿条2385相对地设置在驱动齿轮2384的两侧,驱动齿轮2384位于出气口2321和进气口2322之间的区域,各齿条2385分别与一个隔热阀芯233形成隔热阀芯233联动结构,以驱动两个隔热阀芯233相互靠近或相互背离,出气口2321和进气口2322分别通过对应的隔热阀芯233控制切断和打开。When the first vent 232 is divided into an air inlet 2322 and an air outlet 2321, please refer to Figures 24-27. In some embodiments, the axis of the driving gear 2384 is parallel to the axis c1 of the first vent 232. There are two racks 2385, and the two racks 2385 are relatively arranged on both sides of the driving gear 2384. The driving gear 2384 is located in the area between the air outlet 2321 and the air inlet 2322. Each rack 2385 forms a linkage structure of the heat-insulating valve core 233 with a heat-insulating valve core 233 to drive the two heat-insulating valve cores 233 to approach or depart from each other. The air outlet 2321 and the air inlet 2322 are respectively controlled to be cut off and opened by the corresponding heat-insulating valve core 233.
如图25所示,当两个齿条2385回缩时,由于隔热阀芯233与齿条2385在图示高度上有重叠,因此最多只能回到图25所示状态,这将造成整个隔离阀组件230在图示左右方向上长度较大。对此,请参考图26,一些实施例中,在隔热阀芯233联动结构中隔热阀芯233与齿条2385在驱动齿轮2384的轴向上形成台阶状,在隔热阀芯233向驱动齿轮2384回缩时,一个隔热阀芯233联动结构的隔热阀芯233与另一个隔热阀芯233联动结构的齿条2385在驱动齿轮2384的轴向上层叠设置。由于该台阶状的结构对隔热阀芯233形成了避让,因此可以将两个隔热阀芯233回缩到更接近的位置,进而减小隔离阀组件230在图示左右方向上长度。As shown in FIG25, when the two racks 2385 are retracted, since the insulation valve core 233 and the rack 2385 overlap in the height shown in the figure, they can only return to the state shown in FIG25 at most, which will cause the entire isolation valve assembly 230 to be relatively long in the left-right direction shown in the figure. In this regard, please refer to FIG26. In some embodiments, in the insulation valve core 233 linkage structure, the insulation valve core 233 and the rack 2385 form a step shape in the axial direction of the driving gear 2384. When the insulation valve core 233 retracts toward the driving gear 2384, the insulation valve core 233 of one insulation valve core 233 linkage structure and the rack 2385 of another insulation valve core 233 linkage structure are stacked in the axial direction of the driving gear 2384. Since the step-shaped structure forms a avoidance for the insulation valve core 233, the two insulation valve cores 233 can be retracted to a closer position, thereby reducing the length of the isolation valve assembly 230 in the left-right direction shown in the figure.
此外,请参考图27,另一个实施例中,该齿条2385与驱动齿轮2384之间啮合设置有至少一个小齿轮2386,以拉开两个齿条2385之间的间隙,在隔热阀芯233向驱动齿轮2384回缩时,隔热阀芯233收纳于间隙中。因此可以将两个隔热阀芯233回缩到更接近的位置,进而减小隔离阀组件230在图示左右方向上长度。In addition, please refer to FIG. 27 , in another embodiment, at least one pinion 2386 is provided between the rack 2385 and the driving gear 2384 to open the gap between the two racks 2385, and when the insulation valve core 233 is retracted toward the driving gear 2384, the insulation valve core 233 is accommodated in the gap. Therefore, the two insulation valve cores 233 can be retracted to a closer position, thereby reducing the length of the isolation valve assembly 230 in the left-right direction of the figure.
进一步地,请参考图24-27,一些实施例中,该对接座231为至少两个,出气口2321和进气口2322分设于两个不同对接座231上,驱动件234位于两个对接座231之间的区域,以充分利用两个对接座231之间的空间,提高结构的紧凑性。Further, please refer to Figures 24-27. In some embodiments, there are at least two docking seats 231, the air outlet 2321 and the air inlet 2322 are respectively arranged on two different docking seats 231, and the driving member 234 is located in the area between the two docking seats 231 to fully utilize the space between the two docking seats 231 and improve the compactness of the structure.
以上各实施例所示的传动机构也可替换为同步带传动副或蜗轮蜗杆传动副等各种已被公开的传动机构。The transmission mechanisms shown in the above embodiments may also be replaced by various publicly known transmission mechanisms such as a synchronous belt transmission pair or a worm gear transmission pair.
进一步地,隔热阀芯233除了上述的平移运动之外,隔热阀芯233同样也可做旋转运动。请参考图28-29,一些实施例中,隔热阀芯233组件还具有导向结构2388,驱动件234相对对接座231固定设置,驱动件234或传动机构输出直线往复运动,隔热阀芯233与导向结构2388配合,将驱动件234输出的直线往复运动转换成隔热阀芯233的旋转往复运动。其中,该驱动件234可为直线电机、气缸、液缸、电磁铁等能够输出直线往复运动的结构,从而由驱动件234直接驱动隔热阀芯233。此外,该驱动件234也可为旋转电机,其输出旋转运动,再通过传动机构将旋转运动转换成往复直线运动,传动机构可采用丝杆螺母传动副、齿轮齿条传动副、同步带传动副或蜗轮蜗杆传动副等等。Further, in addition to the above-mentioned translational motion, the heat-insulating valve core 233 can also perform rotational motion. Please refer to Figures 28-29. In some embodiments, the heat-insulating valve core 233 assembly also has a guide structure 2388, the driving member 234 is fixedly arranged relative to the docking seat 231, the driving member 234 or the transmission mechanism outputs linear reciprocating motion, and the heat-insulating valve core 233 cooperates with the guide structure 2388 to convert the linear reciprocating motion output by the driving member 234 into the rotational reciprocating motion of the heat-insulating valve core 233. Among them, the driving member 234 can be a structure that can output linear reciprocating motion, such as a linear motor, a cylinder, a liquid cylinder, an electromagnet, etc., so that the heat-insulating valve core 233 is directly driven by the driving member 234. In addition, the driving member 234 can also be a rotary motor, which outputs rotary motion, and then converts the rotary motion into reciprocating linear motion through a transmission mechanism. The transmission mechanism can adopt a screw nut transmission pair, a gear rack transmission pair, a synchronous belt transmission pair, or a worm gear transmission pair, etc.
请参考图28-29,一些实施例中,隔热阀芯233相对对接座231转动连接,对接座231上的导向结构2388为凸起设置的导柱,隔热阀芯233设有与导柱配合的导槽,驱动件234驱动导柱往复直线运动,以带动隔热阀芯233旋转。和/或,在其他实施例中,对接座231上导向结构2388也可替换为导槽,隔热阀芯233设有与导槽配合的导柱。Please refer to Figures 28-29, in some embodiments, the heat-insulating valve core 233 is rotatably connected relative to the docking seat 231, the guide structure 2388 on the docking seat 231 is a guide column with a protruding arrangement, the heat-insulating valve core 233 is provided with a guide groove that matches the guide column, and the driving member 234 drives the guide column to reciprocate linearly to drive the heat-insulating valve core 233 to rotate. And/or, in other embodiments, the guide structure 2388 on the docking seat 231 can also be replaced with a guide groove, and the heat-insulating valve core 233 is provided with a guide column that matches the guide groove.
具体地,该驱动件234为旋转电机,该传动机构为丝杆螺母传动副,该丝杆螺母传动副的 螺母2382与导柱或导槽联动,当驱动该导柱或导槽做直线往复运动时,由于隔热阀芯233只能转动,因此该直线往复运动将转换为隔热阀芯233的旋转运动,进而切断和打开进气口2322和出气口2321。Specifically, the driving member 234 is a rotating motor, and the transmission mechanism is a screw-nut transmission pair. The nut 2382 of the screw-nut transmission pair is linked with the guide column or guide groove. When the guide column or guide groove is driven to perform linear reciprocating motion, since the thermal insulation valve core 233 can only rotate, the linear reciprocating motion will be converted into a rotational motion of the thermal insulation valve core 233, thereby cutting off and opening the air inlet 2322 and the air outlet 2321.
进一步地,该驱动件234可被安装在对接座231上,也可被安装在其他结构,例如安装在相对对接座231固定的其他结构,如制冷仓221、隔层板2216、烹饪仓120或其他结构等等。Furthermore, the driving member 234 can be installed on the docking seat 231, or can be installed on other structures, for example, other structures fixed relative to the docking seat 231, such as the refrigeration chamber 221, the partition plate 2216, the cooking chamber 120 or other structures, etc.
请参考图8、15和16,一些实施例中,该隔离阀组件230包括驱动件支架2387,驱动件支架2387相对对接座231固定设置,驱动件234安装在驱动件支架2387上。为了使结构更加紧凑,该驱动件支架2387与对接座231之间留出隔热阀芯通道2388,隔热阀芯233位于隔热阀芯通道2388内,并穿过驱动件支架2387。在图8、15和16所示实施例中,该驱动件支架2387安装在对接座231(或盖体231)上,当然,在其他实施例中,该驱动件支架2387也可安装在其他结构上,例如安装在制冷仓221的隔层板2216或者基座2214上。Please refer to Figures 8, 15 and 16. In some embodiments, the isolation valve assembly 230 includes a driver bracket 2387, which is fixedly arranged relative to the docking seat 231, and the driver 234 is installed on the driver bracket 2387. In order to make the structure more compact, a heat-insulating valve core channel 2388 is reserved between the driver bracket 2387 and the docking seat 231. The heat-insulating valve core 233 is located in the heat-insulating valve core channel 2388 and passes through the driver bracket 2387. In the embodiments shown in Figures 8, 15 and 16, the driver bracket 2387 is installed on the docking seat 231 (or the cover body 231). Of course, in other embodiments, the driver bracket 2387 can also be installed on other structures, such as the interlayer plate 2216 or the base 2214 of the refrigeration chamber 221.
进一步地,该阀芯既要顺畅运行,又要保证一定的密封性,在阀体设计领域是个难题。为了实现较好的密封效果,不但对阀芯材料耐磨性有较高要求,对零件表面的加工精度要求也较高,有的甚至需要对阀芯接触配合表面进行镀膜处理或强化表面处理,这极大增加了阀体的制造成本。并且,由于一般阀体采用接触面配合实现密封,对阀体零件的装配工艺要求较高,这同样增加了阀体的安装成本。Furthermore, the valve core must operate smoothly while ensuring a certain degree of sealing, which is a difficult problem in the field of valve body design. In order to achieve a better sealing effect, not only is there a high requirement for the wear resistance of the valve core material, but also a high requirement for the machining accuracy of the parts surface. Some even require the valve core contact and matching surface to be plated or strengthened, which greatly increases the manufacturing cost of the valve body. In addition, since the general valve body uses contact surface matching to achieve sealing, the assembly process of the valve body parts is required to be high, which also increases the installation cost of the valve body.
为了能够在保证隔热阀芯233顺畅运行以及保证密封性的同时,简化隔热阀芯233及其配合件的加工工艺和装配要求,请参考图15和17,一些实施例中,该隔离阀组件230还包括弹性预紧件239,该弹性预紧件239直接或间接作用于隔热阀芯233上,并向隔热阀芯233提供促使隔热阀芯233抵压对接座231的预紧力,以提高隔热阀芯233与第一通气口232的密封效果。In order to simplify the processing technology and assembly requirements of the thermal insulation valve core 233 and its matching parts while ensuring the smooth operation and sealing of the thermal insulation valve core 233, please refer to Figures 15 and 17. In some embodiments, the isolation valve assembly 230 also includes an elastic preload 239, which directly or indirectly acts on the thermal insulation valve core 233 and provides a preload force to the thermal insulation valve core 233 to force the thermal insulation valve core 233 to press against the docking seat 231, so as to improve the sealing effect between the thermal insulation valve core 233 and the first air vent 232.
该弹性预紧件239可作用于隔热阀芯233的一处或多处。该弹性预紧件239可作为一个或多个。弹性压紧件可直接连接到隔热阀芯233上,也可以连接于与隔热阀芯233联动的结构上。该弹性预紧件239对隔热阀芯233的预紧力能够促使隔热阀芯233更紧密的抵接对接座231,进而更加贴合第一通气口232的端面,实现更好的密封。The elastic preload member 239 can act on one or more places of the thermal insulation valve core 233. The elastic preload member 239 can be used as one or more. The elastic pressing member can be directly connected to the thermal insulation valve core 233, or can be connected to a structure linked to the thermal insulation valve core 233. The preload force of the elastic preload member 239 on the thermal insulation valve core 233 can cause the thermal insulation valve core 233 to abut against the docking seat 231 more closely, thereby more closely fitting the end face of the first vent 232 to achieve better sealing.
由于设置了弹性预紧件239,因此可降低对隔热阀芯233以及与隔热阀芯233接触的其他部件(如对接座231)的表面加工要求以及装配要求,即使其他部件或者隔热阀芯233表面存在缺陷,如不够平滑或凹凸不平,也可通过弹性预紧件239而自适应地调整,进而可稳定地与对接座231相对运动,并且更加紧密的与第一通气口232的端面贴合,这降低了各部件表面加工精度的要求,各零部件安装简单、可靠、耐糙性强,极大提高了整个阀体的可靠性以及耐糙性,既有利于降低加工成本,也便于降低装配难度。Since the elastic preload 239 is provided, the surface processing requirements and assembly requirements for the thermal insulation valve core 233 and other components in contact with the thermal insulation valve core 233 (such as the docking seat 231) can be reduced. Even if there are defects on the surface of other components or the thermal insulation valve core 233, such as not being smooth enough or being uneven, it can be adaptively adjusted through the elastic preload 239, so that it can stably move relative to the docking seat 231 and fit more closely with the end face of the first air vent 232. This reduces the requirements for the surface processing accuracy of each component, and each component is simple, reliable, and highly resistant to roughness, which greatly improves the reliability and roughness resistance of the entire valve body, which is beneficial to reducing processing costs and reducing assembly difficulty.
进一步地,一些实施例中,该弹性预紧件239包括第一弹性件2391,该驱动件234的输出端与隔热阀芯233通过第一弹性件2391形成浮动连接,第一弹性件2391用于向隔热阀芯233提供驱动隔热阀芯233向对接座231运动的弹性回复力,以促使隔热阀芯233贴合对接座231。当驱动件234的输出端与隔热阀芯233之间设有传动机构时,该第一弹性件2391可设于传动机构和隔热阀芯233之间。Furthermore, in some embodiments, the elastic preload member 239 includes a first elastic member 2391, and the output end of the driving member 234 forms a floating connection with the heat-insulating valve core 233 through the first elastic member 2391. The first elastic member 2391 is used to provide the heat-insulating valve core 233 with an elastic restoring force that drives the heat-insulating valve core 233 to move toward the docking seat 231, so as to cause the heat-insulating valve core 233 to fit the docking seat 231.

In some embodiments, the transmission mechanism is a gear rack mechanism. The rack 2385 is movably connected to the heat-insulating valve core 233, and a first elastic member 2391 is provided between the rack 2385 and the heat-insulating valve core 233. The first elastic member 2391 is used to provide an elastic restoring force to the heat-insulating valve core 233 to drive the heat-insulating valve core 233 to move toward the docking seat 231, so as to cause the heat-insulating valve core 233 to fit the docking seat 231.

进一步地,除了在驱动件234的输出端与隔热阀芯233形成浮动连接结构之外,还可在第 一通气口232处设置其他弹性预紧件239,以加强隔热阀芯233与第一通气口232的密封效果。一些实施例中,还包括第二弹性件2392,第二弹性件2392用于向隔热阀芯233提供使隔热阀芯233压紧第一通气口232的预紧力。Furthermore, in addition to forming a floating connection structure between the output end of the driving member 234 and the heat-insulating valve core 233, another elastic pre-tightening member 239 may be provided at the first vent 232 to enhance the sealing effect between the heat-insulating valve core 233 and the first vent 232. In some embodiments, a second elastic member 2392 is further included, and the second elastic member 2392 is used to provide a pre-tightening force to the heat-insulating valve core 233 so that the heat-insulating valve core 233 presses the first vent 232.

In some embodiments, the pressure seat 240 has a docking port 241, which is connected to the first air vent 232. The valve core movement gap 237 is located between the docking port 241 and the first air vent 232. The end of the docking port 241 away from the first air vent 232 is used to communicate with the cooking cavity 122 or the refrigeration cavity 2211. The insulation valve core 233 can control the on and off states of the cooking cavity 122 and the refrigeration cavity 2211 by cutting off and opening the channel between the docking port 241 and the first air vent 232.
当然,在其他实施例中,该抵压座240也可只起到抵压隔热阀芯233的作用,不用于连通制冷腔2211和烹饪腔122。Of course, in other embodiments, the pressing seat 240 may only play the role of pressing the heat-insulating valve core 233 and is not used to connect the refrigeration cavity 2211 and the cooking cavity 122.

The protrusion 244 can reduce the contact area between the pressing seat 240 and the docking seat 231 and the heat-insulating valve core 233, so that the pressing force between the two is more concentrated and larger, thereby improving the sealing performance. Please refer to FIG9 and 15 , in some embodiments, the protrusion 244 can be a closed annular structure.

The mechanical limit structure 247 is located on the movement trajectory of the thermal insulation valve core 233 or other components linked to the thermal insulation valve core 233, and is used to block the movement of the thermal insulation valve core 233 or other components linked to the thermal insulation valve core 233. The mechanical limit structure 247 is usually a bump or other mechanical structure that can block the movement of the thermal insulation valve core 233 and other components linked to the thermal insulation valve core 233. Of course, correspondingly, the thermal insulation valve core 233 is also provided with a protrusion 2333 that cooperates with the position detection unit 246 and/or the mechanical limit structure 247, so as to trigger the position detection unit 246 and/or form a limit with the mechanical limit structure 247.
