Description

Technical Field

[0001] The utility model relates to the technical field of space cooking, in particular to an integrated hot and cold cooking machine. 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 order to achieve high-temperature cooking of space food in the microgravity environment of space, an existing solution is to collect the fumes generated by high-temperature heating of packaged food by cooking equipment through air collection bags, and then put the air collection bags into cooling equipment for cooling and liquefaction after the high-temperature heating is completed, so as to realize the recovery of residual gas.

[0004] However, among the equipment currently in the space station: both the cooking equipment and the cooling equipment are independent and separate; therefore, not only is it difficult for astronauts to judge the degree of sufficiency of oil fume collection during the collection process, which may easily lead to incomplete oil fume collection and oil fume leakage, but also the air collection bag needs to be removed from the cooking equipment after the collection is completed and manually moved to the cooling equipment, which increases the difficulty of operation and workload of the astronauts.

[0028] 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.

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.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" 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.

[0032] Considering that the cooking equipment and cooling equipment in the space station are currently separated, it is difficult for astronauts to judge the adequacy of oil fume collection during the collection process, which easily leads to the problem of oil fume leakage due to incomplete oil fume collection. In addition, the air collection bag needs to be taken out of the cooking equipment and manually moved to the cooling equipment after the collection is completed, which increases the difficulty of operation and workload of astronauts. Therefore, the utility model provides a hot and cold cooking all-in-one machine, which can solve the problems of incomplete oil fume collection, difficulty of operation and large workload.

[0033] Specifically, refer to the attached Figures 1 to 4 As shown, an embodiment of the present application provides an all-in-one hot and cold cooking machine 1, which can heat the packaged food 50 at high temperature and collect the oil fume generated by the packaged food 50 at low temperature. It can not only thoroughly collect the oil fume and avoid the problem of oil fume escape, but also reduce the difficulty of cooking operations and reduce the workload of astronauts.

[0034] More specifically, if Figure 2 As shown, the hot and cold cooking machine 1 may include a door box assembly 10, a heating device 20, a collecting device 30 and a refrigerating device 40. The door box assembly 10 has a heating chamber 101 and a cooling chamber 102 which are arranged at intervals and isolated from each other; the heating device 20 is arranged in the heating chamber 101, and is used to heat the packaged food 50 placed in the heating chamber 101; the collecting device 30 includes a gas collecting container 31 arranged in the cooling chamber 102 and a connecting member 32 connected to the gas collecting container 31, the connecting member 32 extends from the cooling chamber 102 to the heating chamber 101, and is used to connect the packaged food 50, so as to form an air path for conveying oil smoke between the gas collecting container 31 and the packaged food 50; the refrigerating device 40 is arranged in the cooling chamber 102, and is used to generate cold in the cooling chamber 102 to cool the oil smoke collected by the gas collecting container 31 while heating the packaged food 50 through the heating device 20.

[0035] In this way, when the heating device 20 generates heat in the heating chamber 101 to heat the packaged food 50 at a high temperature, the oil smoke generated by the packaged food 50 will be transported to the gas collecting container 31 located in the cooling chamber 102 via the connecting piece 32; at the same time, the refrigeration device 40 generates cold energy in the cooling chamber 102 to cool the oil smoke collected by the gas collecting container 31, so that the oil smoke in the gas collecting container 31 is quickly liquefied when it is cooled, ensuring that the gas collecting container 31 always maintains a low pressure, that is, the air pressure in the gas collecting container 31 is always lower than the air pressure in the packaged food 50, which is conducive to the high-temperature oil smoke flowing smoothly from the packaged food 50 to the gas collecting container 31 through the connecting piece 32 to be collected and recycled. In particular, after the packaged food 50 is heated at a high temperature, the refrigeration device 40 can continue to work for a period of time to thoroughly collect the oil smoke generated by the heating of the packaged food 50, so that there is no oil smoke residue and the phenomenon of oil smoke escaping is avoided.

[0036] It is worth noting that the hot and cold cooking all-in-one machine 1 of the present application integrates high-temperature heating and cooking functions and low-temperature refrigeration and collection functions, does not occupy too many resources in the space station, and can not only heat the packaged food 50 at high temperature while cooling the oil fume collected by the gas collecting container 31 to completely collect the oil fume and prevent the oil fume from escaping; but also does not require astronauts to move the gas collecting container 31 that collects the oil fume to other independent refrigeration equipment for cooling, thereby reducing the operating difficulty and workload of astronauts.

[0037] For example, Figure 1 , Figure 2 as well as Figure 4 As shown, the door box assembly 10 includes a box body 11 with an opening, a partition 12 arranged inside the box body 11 to separate the box body 11 into the heating chamber 101 and the cooling chamber 102, and a pair of door bodies 13 movably arranged on the box body 11 and corresponding to the heating chamber 101 and the cooling chamber 102 respectively; the connecting member 32 is implemented as a connecting pipe 320 passing through the partition 12, one end of the connecting pipe 320 is connected to the gas collecting container 31, and the other end of the connecting pipe 320 is used to connect the packaged food 50. In this way, when the astronauts want to heat food, they only need to open the door body 13 in the door box assembly 10 corresponding to the heating chamber 101, put the packaged food 50 into the heating chamber 101 and connect it to the connecting pipe 320; then close the door body 13 to seal the heating chamber 101; thereafter, the heating device 20 generates heat in the heating chamber 101 to heat the packaged food 50, and the refrigeration device 40 generates cold in the cooling chamber 102 to cool the gas collecting container 31, so that the oil smoke generated by the packaged food 50 flows into the gas collecting container 31 for condensation recovery.

[0038] Alternatively, if Figure 1 and Figure 2 As shown, the partition 12 is located in the middle of the box 11, so that the heating chamber 101 and the cooling chamber 102 are arranged in the box 11 at intervals on the left and right sides; the two doors 13 are rotatably connected to the left and right side walls of the box 11, so as to open the doors opposite to each other. It can be understood that the box 11, the partition 12 and the door 13 mentioned in the present application are all made of heat insulation materials, so as to play a heat preservation function, reduce heat exchange, and avoid energy waste.

[0039] Alternatively, if Figure 2 As shown, the connecting tube 320 is fixedly connected to the partition 12 so that the connecting tube 320 can be restrained by the partition 12, and then the gas collecting container 31 and the packaged food 50 can be restrained by the connecting tube 320. There is no need to use additional restraining parts to restrain the gas collecting container 31 and the packaged food 50, which helps to simplify the operation of astronauts and reduce equipment costs.

[0040] Alternatively, if Figure 4 As shown, the box 11 has a slot 110 that matches the partition 12, and the partition 12 can be slidably inserted into the slot 110 to achieve a fixed connection between the partition 12 and the box 11 when the door is closed, so as to ensure reliable isolation between the heating chamber 101 and the cooling chamber 102 and reduce the efficiency of heat exchange. In this way, the astronaut can first take out the partition 12 together with the connecting pipe 320 and the gas collecting container 31 from the box 11 when opening the door, so as to conveniently connect the packaged food 50 with the connecting pipe 320 outside the box 11; and then close the door after inserting the partition 12 into the slot 110 of the box 11 to complete the assembly and fixation, which helps to reduce the difficulty of assembly.

[0041] Alternatively, if Figure 3 As shown, the gas collecting container 31 includes a gas collecting bag 311 and a sealing valve 312 heat-sealed and fixedly connected to the gas collecting bag 311. The sealing valve 312 is detachably connected to the connecting pipe 320, so that when the gas collecting bag 311 is full of oil smoke, the gas collecting bag 311 is first sealed by the sealing valve 312 to prevent the collected oil smoke from leaking; then the sealing valve 312 is removed from the connecting pipe 320 and replaced with an empty gas collecting container 31 to continue collecting oil smoke. It can be understood that the valve port of the sealing valve 312 of the present application can be sealed and plugged into one end of the connecting pipe 320 to achieve a sealed connection between the two. Of course, in other examples of the present application, the gas collecting container 31 can also be implemented as other types of containers with a sealing valve 312, as long as it can collect oil smoke.

[0042] It is worth noting that although the temperature of the heating chamber 101 can be above 150°C, the hot and cold cooking machine 1 only needs to set the material of the connecting pipe 320 to be able to withstand the high temperature of more than 150°C in the heating chamber. The gas collecting container 31 in the hot and cold cooking machine 1 does not require high temperature resistant materials, which helps to reduce costs.

[0043] In addition, if Figure 3 As shown, the packaged food 50 may include a food package 51 for detachably connecting to the connecting tube 320 and food 52 located in the food package 51. It is understood that the food package 51 of the present application may be implemented as a packaging box or a packaging bag, but is not limited to, so that the packaged food 50 forms a boxed food or a bagged food. The food package 51 of the present application can withstand a temperature above 200°C, so as to adapt to high temperature cooking.

[0044] Optionally, the food bag 51 is plugged and fixed to one end of the connecting tube 320 .

[0045] According to the above embodiments of the present application, Figure 2 As shown, the refrigeration device 40 in the hot and cold cooking machine 1 can be, but is not limited to, implemented as a semiconductor refrigerator 41 fixedly installed in the cooling chamber 102 to meet the space station's restrictions on volume, weight and power.

[0046] Optionally, the temperature of the cooling chamber 102 is about 5° C., so as to reduce energy consumption and save energy in the station while meeting the demand for oil fume cooling.

[0047] Alternatively, if Figure 2As shown, the heating device 20 in the hot and cold cooking machine 1 includes a heat generating component 21 disposed in the heating chamber 101 and used to generate heat in the heating chamber 101, and a hot air circulation component 22 disposed in the heating chamber 101; the hot air circulation component 22 includes a fan 221 and a pair of air supply channels 222 connected to the air outlet of the fan 221 and arranged at intervals from each other, each of the air supply channels 222 is provided with a plurality of nozzles facing the other air supply channel 222, so as to form a convection space 220 for accommodating the packaged food 50 between the two air supply channels 222. In this way, when the heat generating component 21 generates heat in the heating chamber 101 to heat the air in the heating chamber 101 to form hot air, the fan 221 ejects the hot air from the nozzle of the air supply channel 222 to directly blow the packaged food 50 located in the convection space 220, so as to efficiently heat the food 52 in the packaged food 50. It can be understood that each air supply channel 222 mentioned in the present application can be provided by one air supply pipe, or by multiple air supply pipes arranged side by side; in addition, the air supply pipe mentioned in the present application can be, but is not limited to, implemented as a round tube, a square tube or a plate tube, etc., as long as it can guide the hot air to blow directly toward the packaged food 50 under the action of the corresponding fan 221, the present application will not go into details about this.

[0048] Alternatively, if Figure 2 As shown, the heat generating component 21 is implemented as a microwave generator 210 fixed in the heating chamber 101. It is understandable that in other examples of the present application, the heat generating component 21 can also be implemented as other devices capable of generating heat, such as electric heating wires or heating tubes, which will not be described in detail in the present application.

[0049] Alternatively, if Figure 2 As shown, the heating device 20 further includes a temperature sensor 23 disposed in the heating chamber 101 for measuring the temperature in the heating chamber 101 so as to control the cooking temperature of the packaged food 50 and obtain a better cooking effect.

[0050] Alternatively, if Figure 2 As shown, the temperature sensor 23 is implemented as an NTC sensor 230 fixedly mounted on the air supply channel 222 and located within the convection space 220 , so as to accurately measure the cooking temperature of the packaged food 50 .

[0051] It is worth mentioning that according to another aspect of the present application, Figure 5 As shown, one embodiment of the present application further provides a hot and cold cooking method, which may include the steps of:

[0052] S100: controlling the heating device to start working to heat the packaged food placed in the heating chamber, so that the oil smoke generated by the packaged food when heated is transported to the gas collecting container located in the cooling chamber through the heating element; and

[0053] S200: Controlling the refrigeration device to start working synchronously to generate cold in the cooling chamber to cool the oil smoke collected by the gas collecting container, so that the air pressure in the gas collecting container is always lower than the air pressure in the packaged food.

[0054] It is worth noting that Figure 5 As shown, the hot and cold cooking method of the present application may further include the steps of:

[0055] S300: After controlling the heating device to stop working, controlling the refrigeration device to stop working after a predetermined delay.

[0056] Optionally, the predetermined time mentioned in the present application is between 3 minutes and 5 minutes, that is, when the packaged food is finished heating and cooking, the heating device is first controlled to stop working, and then the refrigeration device is controlled to stop working after a delay of 3 minutes to 5 minutes, so as to continuously collect the oil smoke and water vapor slowly emitted by the packaged food, ensure the thorough collection of the oil smoke, and facilitate to ensure that all oil smoke in the packaged food and the connecting pipe is free of residue.

[0057] 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.

[0058] 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.
