Description
Technical Field
[0001] The utility model relates to the technical field of space cooking, in particular to an oil fume collection device, a food package and a cooking utensil. Background Art
[0002] Astronauts are a special group of people who work in a microgravity environment. Not only is the diversity of their food greatly limited, but the way they cook food is even more limited. At present, during space flight, space food is usually heated in a low-temperature water bath or hot air circulation, and the highest heating temperature is mostly concentrated between 80°C and 90°C. This low-temperature cooking method will limit the taste and flavor of the food to a certain extent, giving astronauts a bad experience. The reason why existing space food is usually cooked by low-temperature heating is that space food is mostly sealed in outer packaging such as food boxes or food bags to form packaged food. When the heating temperature is high, a large amount of oil smoke will be generated, which can easily burst the outer packaging of space food, not only posing a safety hazard, but the leaked oil smoke will also give astronauts a bad experience.
[0003] In addition, if the outer packaging of space food is torn open and then heated, the fumes produced by the heating will accumulate in the cooking utensils. When astronauts take food out of the cooking utensils, the fumes in the cooking utensils will not only fly towards the astronauts' faces, giving them a poor experience, but the water vapor in the fumes will condense into water droplets when it gets cold and float in the spacecraft, posing a great hidden danger to the safe operation of the spacecraft.

[0016] Bags, used to package food; and
[0017] A connecting valve component installed on the packaging bag, the connecting valve component includes a first valve interface fixedly connected to the packaging bag, a second valve interface for docking with a connecting pipe, an open valve cavity located between the first valve interface and the second valve interface and connected to the first valve interface and the second valve interface, and a sealing valve body slidably inserted into the open valve cavity and interference fit with the open valve cavity; when the sealing valve body is pulled up to be pulled out from the open valve cavity, the sealing valve body clears the open valve cavity to conduct the air path between the first valve interface and the second valve interface; when the sealing valve body is pressed to be inserted into the open valve cavity, the sealing valve body blocks the open valve cavity to block the air path between the first valve interface and the second valve interface.

[0036] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

[0037] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] Considering that existing space food (packaged food such as boxed food or bagged food) is not suitable for high-temperature cooking in the microgravity environment of space, it can only be cooked at low temperature by means of low-temperature water bath or hot air circulation heating, and low-temperature cooking not only has a slow heating speed, but also limits the taste and flavor of food to a certain extent, affecting the diet of astronauts. Therefore, in view of the problem that space food cannot be cooked at high temperature in the microgravity environment of space, the utility model provides a fume collection device, a food package and a cooking utensil, which can make it possible to cook space food at high temperature in the microgravity environment of space, so as to improve the taste and flavor of food while ensuring safety.
[0041] Specifically, refer to the attached Figures 1 to 11 As shown, one embodiment of the present application provides a cooking appliance 1, which may include a heating cavity 10 for heating packaged food 30 and an oil fume collection device 20 for connecting with the packaged food 30, so as to collect the oil fume generated when the packaged food 30 is heated in the heating cavity 10 through the oil fume collection device 20.
[0042] More specifically, if Figures 2 to 11 As shown, the oil fume collection device 20 may include a gas collecting container 21 and a connecting valve member 22 installed on the gas collecting container 21; the connecting valve member 22 includes a first valve interface 221 fixedly connected to the gas collecting container 21, a second valve interface 222 for communicating with the packaged food 30, an open valve cavity 223 located between the first valve interface 221 and the second valve interface 222 and communicating with the first valve interface 221 and the second valve interface 222, and a slidable plug in the open valve cavity 223 And a sealing valve body 224 that is interference fit with the open valve cavity 223; when the sealing valve body 224 is pulled up to be pulled out from the open valve cavity 223, the sealing valve body 224 clears the open valve cavity 223 to conduct the air path between the first valve interface 221 and the second valve interface 222; when the sealing valve body 224 is pressed to be inserted into the open valve cavity 223, the sealing valve body 224 blocks the open valve cavity 223 to block the air path between the first valve interface 221 and the second valve interface 222.
[0043] It is worth noting that due to Figure 5 and Fig.10 As shown, after the sealing valve body 224 is lifted to open the air path between the first valve interface 221 and the second valve interface 222, the air path between the packaged food 30 and the gas collecting container 21 is opened, so that the oil smoke generated by the heating of the packaged food 30 can flow into the gas collecting container 21 to be collected. Therefore, the heating cavity 10 of the present application can provide a high temperature environment of more than 150°C, so as to perform high-temperature heating on the packaged food 30 placed in the heating cavity 10, greatly improve the heating speed, realize high-temperature cooking in the microgravity environment of space, shorten the cooking time, and do not have to worry about oil smoke leakage, pollution and other problems.
[0044] In addition, if Figure 6 and Fig.10 As shown, after pressing the sealing valve body 224 to block the air path between the first valve interface 221 and the second valve interface 222, the air path between the packaged food 30 and the gas collecting container 21 is also blocked, preventing the oil smoke collected in the gas collecting container 21 from escaping so that it can be sent for cooling to liquefy the water vapor in the oil smoke and achieve recycling.
[0045] For example, in the first example of the present application, Figures 2 to 6 As shown, the open valve chamber 223 can be implemented as a columnar cavity having a cylindrical groove 2231, the notch of the cylindrical groove 2231 is located at one end of the columnar cavity, and the first valve interface 221 and the second valve interface 222 are integrally connected to the circumference of the columnar cavity to form a vertical valve chamber.
[0046] At the same time, Figure 3 and Figure 4 As shown, the sealing valve body 224 includes a cylindrical valve core 2241 matching the cylindrical groove 2231, a sealing sleeve 2242 sleeved on the cylindrical valve core 2241, and a handle 2243 fixedly connected to the cylindrical valve core 2241 and extending out of the cylindrical groove 2231; the outer diameter of the sealing sleeve 2242 is larger than the inner diameter of the cylindrical groove 2231 to form an interference fit for sealing. It is understandable that the sealing sleeve 2242 of the present application can be fixedly sleeved on the outer surface of the cylindrical valve core 2241 by gluing.
[0047] Furthermore, in the second example of the present application, Figures 7 to 11As shown, the open valve cavity 223 can be implemented as a columnar cavity with a rectangular groove 2232, the notch of the rectangular groove 2232 can be located on the circumference of the columnar cavity, and the first valve interface 221 and the second valve interface 222 are integrally connected to the two ends of the columnar cavity to form a transverse valve cavity. It can be understood that, compared with the vertical valve cavity in the first example above, the transverse valve cavity in the second example of the present application helps to reduce the overall height of the connecting valve member 22, which is more conducive to the pouring out of the liquefied water later.
[0048] At the same time, Figure 8 and Fig. 9 As shown, the sealing valve body 224 correspondingly includes a flat valve core 2244 matching the rectangular groove 2232, a sealing gasket 2245 attached to the flat valve core 2244 and corresponding to the side wall of the rectangular groove 2232, a sealing ring 2246 arranged at both ends of the rectangular groove 2232 and abutting against the flat valve core 2244, and a handle 2243 fixedly connected to the flat valve core 2244 and extending out of the rectangular groove 2232; so that the rectangular groove 2232 can be completely sealed on all sides by the sealing gasket 2245 and the sealing ring 2246.
[0049] It is worth noting that the connecting valve component 22 of the present application is not only light and easy to process, fully meeting aerospace requirements, but also very convenient to operate. Astronauts only need to perform simple preliminary connections and press or pull the valve body to collect oil fumes; at the same time, the oil fume collection device 20 of the present application can be recycled, which is convenient for saving aerospace resources.
[0050] According to the above embodiments of the present application, Figure 2 and Figure 7 As shown, the gas collecting container 21 is implemented as a gas collecting bag 210 heat-sealed and fixedly connected to the first valve interface 221. It is deflated in the airless state for easy storage; and swells in the air collecting state for easy collection of more oil smoke. Of course, in other examples of the present application, the gas collecting container 21 can also be implemented as other types of containers such as balloons, as long as the volume can be changed.
[0051] Alternatively, if Figures 1 to 11As shown, the oil fume collecting device 20 may also include a connecting pipe 23, one end of which is detachably connected to the second valve interface 222 of the connecting valve member 22, and the other end of the connecting pipe 23 is used to connect to the packaged food 30, so as to establish an air path for conveying oil fume between the gas collecting container 21 and the packaged food 30. It can be understood that the oil fume collecting device 20 of the present application can utilize the detachable connection between the connecting pipe 23 and the second valve interface 222, not only to disassemble the gas collecting container 21 with the connecting valve member 22 for cooling and recovering water vapor in the oil fume, but also to conveniently replace different gas collecting containers 21 to meet the collection needs of large-capacity oil fume.
[0052] Alternatively, if Figure 6 and Fig.11 As shown, the connecting valve member 22 further includes a sealing ring 225 sleeved on the second valve interface 222, one end of the connecting pipe 23 is sleeved on the second valve interface 222, and the sealing ring 225 is located between the second valve interface 222 and the connecting pipe 23 to achieve a sealed connection between the connecting pipe 23 and the second valve interface 222 to avoid oil fume leakage.
[0053] Optionally, the second valve interface 222 is provided with a mounting groove matching the sealing ring 225 to limit the position of the sealing ring 225 to avoid axial sliding along the second valve interface 222 when docking with the connecting pipe 23, thereby ensuring a better sealing effect.
[0054] It is worth noting that the materials of each component in the oil fume collecting device 20 can withstand the high temperature of more than 150°C in the cavity. Preferably, each component in the oil fume collecting device 20 is made of high temperature resistant materials that can withstand more than 200°C. Figure 1 As shown, the oil fume collection device 20 connected to the packaged food 30 can be placed together in the heating cavity 10 for high-temperature heating, without reserving an opening on the heating cavity 10 for the connecting pipe 23 to pass through, so as to prevent the heat energy in the heating cavity 10 from being lost. It is understandable that in other examples of the present application, the gas collecting container 21 in the oil fume collection device 20 can also collect gas outside the heating cavity 10. In this case, it is necessary to reserve an opening on the heating cavity 10 for the connecting pipe 23 to pass through, so as to communicate with the packaged food 30 located in the heating cavity 10, and this application will not repeat it.
[0055] According to the above embodiments of the present application, Figure 1As shown, the packaged food 30 may include a food package 31 for communicating with the oil fume collecting device 20 and food (not shown) in the food package 31. It is understood that the food package 31 of the present application may be, but is not limited to, implemented as a packaging box or a packaging bag, so that the packaged food 30 forms a boxed food or a bagged food. The food package 31 of the present application can withstand a temperature of more than 200°C, so as to adapt to high temperature cooking.
[0056] It is worth mentioning that according to another aspect of the present application, Figure 1 As shown, an embodiment of the present application further provides a food package 31, which may include a packaging bag 310 for packaging food and the above-mentioned connecting valve member 22, wherein the first valve interface 221 of the connecting valve member 22 is fixedly connected to the packaging bag 310, and the second valve interface 222 of the connecting valve member 22 is used to connect to the connecting pipe 23 of the oil fume collection device 20 to form an openable and closable air path between the gas collecting container 21 and the packaging bag 310.
[0057] In this way, the sealing valve bodies 224 of the two connecting valve members 22 are first pressed to block the open valve chamber 223, and then the second valve interfaces 222 of the connecting valve members 22 in the oil fume collecting device 20 and the food package 31 are respectively connected to the two ends of the connecting pipe 23, and then Figure 5 and Fig.10 As shown, the sealing valve bodies 224 of the two connecting valve members 22 are pulled up (the pulling height is not to fall out of the corresponding open valve chambers 223), so that the gas path between the gas collecting container 21 and the packaging bag 310 is connected / conducted; at this time, the heating chamber 10 starts to heat the food bag 31 at a high temperature, and the oil smoke generated by the food in the food bag 31 will flow to the gas collecting container 21 with lower pressure (the gas collecting container 21 has been partially evacuated in advance) by its own molecular thermal motion; after the heating is completed, as shown in FIG. Figure 6 and Fig.11 As shown, the sealing valve bodies 224 of the two connecting valve members 22 are pressed again to block the gas path between the gas collecting container 21 and the packaging bag 310; then the food package 31 and the oil fume collecting device 20 are removed respectively, on the one hand, the packaging bag 310 of the food package 31 is cut open to take out the food, and on the other hand, the oil fume collecting device 20 is sent for cooling to liquefy the water vapor in the oil fume and pour it out for recycling.
[0058] It is worth noting that when the heating cavity 10 heats the packaged food 30, the sealing valve body 224 of the connecting valve member 22 is pulled up, so that the gas collecting container 21 in the oil fume collection device 20 can collect the oil fume generated by the food in the packaged food 30. Therefore, the heating cavity 10 can heat the packaged food 30 at high temperature, thereby preventing the packaged food 30 from generating a large amount of oil fume due to high-temperature cooking and bursting the food package 31, making it possible to perform high-temperature cooking of the packaged food 30 in the microgravity environment of space, which is beneficial to improving the taste and flavor of the food.
[0059] In addition, after the packaged food 30 has completed high-temperature cooking, the sealing valve body 224 of the connecting valve member 22 is pressed, so that the oil smoke collected by the gas collecting container 21 will not only not flow back to the food package 31, but also will not enter the heating cavity 10. In this way, when astronauts take food out of the cooking utensils, there will be no problem of oil smoke flying towards the astronauts' faces, and there will be no water droplets formed by condensation of water vapor in the oil smoke when it is condensed and floating in the spacecraft, thereby avoiding great hidden dangers to the safe operation of the spacecraft.
[0060] Of course, in other embodiments of the present application, the connecting valve member 22 and the connecting pipe 23 may also be replaced by a hose and a water stop clamp / spring clamp, which will not be described in detail in the present application.
[0061] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
