Referring to fig. 1-9B, the invention provides a fresh-keeping machine, which comprises a machine cover 1, a fresh-keeping machine body 2 and a main machine box 3, wherein the machine cover 1 is preferably in rotary connection with the fresh-keeping machine body 2, the fresh-keeping machine body 2 is fresh-keeping equipment adopting a liquid quick-freezing flash freezing technology, and is mainly used for quick freezing and fresh-keeping of food materials, the technology utilizes a cryogenic mechanical refrigerating unit to provide a cold source, the food materials are immersed in special food-grade carrier cold liquid, heat of frozen food is taken away by ultra-fast, and the fresh-keeping machine body 2 is in the prior art and is not excessively described herein; two mounting grooves 4 have been seted up to the top symmetry of lock bright machine body 2, simultaneously, in order to be suitable for different application scenario, for example domestic and on-vehicle two kinds of scenes, still provide the mounting bracket subassembly of an regulation size to make the user purchase one set of mounting bracket subassembly and the mounting groove 4 on domestic lock bright machine and the on-vehicle lock bright machine cooperate according to two kinds of different application scenario, reduced user's purchase cost. The fresh-keeping machine body 2 is internally provided with 2/3 volume of refrigerating fluid, the bottom in the cavity is fixedly provided with a refrigerating pipe 12, namely, the refrigerating fluid is refrigerated through the refrigerating pipe 12, the main cabinet 3 is internally provided with a controller and a refrigerating system, the refrigerating system mainly comprises an evaporator, a compressor and a condenser, the refrigerating pipe 12 is a part of a refrigerating circulation system and is used for circulating refrigerant to absorb and release heat, thereby maintaining the low-temperature environment in the fresh-keeping machine body 2, the refrigerating system is an important component of the refrigerating system, and the refrigerating system is the prior art and is not excessively described herein.

Further, the mounting rack assembly comprises two racks 5 and a plurality of support bars for hanging articles, and a first storage bag 9, a second storage bag 10 and a third storage bag 11 for storing different articles, so that a user can select a proper storage bag for containing food according to different use scenes and different fresh-keeping articles. Although the use of dedicated food-grade liquids for direct contact with food is desirable, in view of food safety concerns, it is generally undesirable to stain or adhere the liquid to the food, and therefore an outer package is required to package the various foods to be frozen. If the partition board in the conventional refrigerator is used for space division and placing objects, direct contact with refrigerating fluid cannot be avoided, and if the storage box is used for containing objects and then the objects are placed in the cavity of the fresh-keeping machine body 2, the problem that the volume is large and two tanks for fresh keeping and freezing are divided because the food in different time periods of a household needs to be stored in a frozen manner unlike the conventional household refrigerator is also faced. The fresh-keeping machine is only used for keeping food fresh in tens of minutes or hours or two or three days in daily at home, for example, the food is put into the fresh-keeping machine for fresh keeping after buying vegetables in the morning, and the food is taken out for cooking in the noon or evening. I.e. it does not need to be stored for a long time, but rather for a short period of time, and is therefore generally much smaller in volume than a conventional refrigerator, slightly larger than the size of a household microwave oven. Therefore, if the storage box is used to package food or other articles (such as beverage or skin care product), not only the occupied space is relatively large, but also the contact distance between the food or articles and the refrigerating fluid is increased, so that the refrigerating effect of the refrigerating fluid cannot be effectively utilized. In view of this, in the present application, in order to ensure flexibility and portability, on the other hand, the space can be reasonably utilized and the freezing effect of the freezing liquid can be utilized to the greatest extent as possible, and the storage bag is made of the material of the conventional plastic bag, so that when the storage bag containing the articles is placed in the freezing liquid, the storage bag is automatically wrapped due to the large freezing liquid density (greater than the water density), and the air in the storage bag is extruded to reach a state close to vacuum, especially when the liquid level of the freezing liquid is over the article level. Moreover, considering the sealing requirements of the storage bags in different sizes and different weights and different application scenes (for example, the sealing requirements of the storage bags are not required because a common freshness locker in a household scene is static, and only one chain clamping air port is needed, and for example, the sealing requirements of the storage bags are high because the freshness locker in a vehicle-mounted scene is dynamic and refrigerating fluid can shake in a cavity, one chain clamping can not be met) different storage bags are provided, and a counterweight is arranged to avoid the problem that lighter articles cannot be put into the refrigerating fluid.

Specifically, the following describes in detail embodiments of different application scenarios.

An embodiment I is an outdoor vehicle-mounted physical fresh-locking machine.

Referring to fig. 1, the vehicle-mounted fresh-locking machine of the present embodiment includes a fresh-locking machine body 2 and a main cabinet 3 arranged in parallel, wherein an organic cover 1 is disposed on one side of the fresh-locking machine body 2 connected with the main cabinet 3, and the organic cover 1 is rotatably connected with the fresh-locking machine body 2 through two hinge hinges.

The fresh-keeping machine comprises a fresh-keeping machine body 2, a refrigerating pipe 12, a refrigerating circulation system, two mounting grooves 4, and a mounting frame assembly, wherein the refrigerating liquid used for keeping fresh is contained in the fresh-keeping machine body 2, the bottom of the fresh-keeping machine body is fixedly connected with the refrigerating pipe 12, the refrigerating pipe 12 is connected with the refrigerating circulation system in a main machine case 3, the two mounting grooves 4 are symmetrically formed in the top of the fresh-keeping machine body 2, and the mounting frame assembly capable of sliding in the length direction of the mounting grooves 4 is arranged between the two mounting grooves 4.

Referring to fig. 2A, in this embodiment, the mounting frame assembly includes at least one first support rod 61 that is telescopic, and a placement frame 5 connected to both ends of the at least one first support rod 61.

Since the fresh locker is dynamic during camping or playing, especially when the road jolts, the fresh locker may vibrate slightly, so that the first support bar 61 and the mounting frame are manufactured by an integral molding process in order to ensure stability and spacing between the support bars. Of course, in the present embodiment, the first support rod 61 may also be slidably mounted in comparison with the mounting frame, so that the spacing between the support rods can be adjusted according to actual needs. Of course, each first support bar 61 may be independently installed between two installation grooves 4, thereby making the degree of freedom of the user to adjust the interval between the support bars greater.

Referring to fig. 3A-3C, in this embodiment, the food storage device further includes a second storage bag 10 for storing food, at least two clips 8 that can be clamped on the first support rod 61, and magnetic blocks 16 are disposed on the clips 8.

When the hanging area 101 of the second storage bag 10 near the opening is covered on the first supporting rod 61 and at least two clips 8 are clamped and connected between the clips 8 and the first supporting rod 61, namely the second storage bag 10 is hung on the first supporting rod 61 and has higher tightness due to gravity and the effect of the clips, and when a heavier article is placed, the effect of the at least two clips 8 ensures the uniformity of stress of the hanging area, compared with the mode of arranging hanging holes or handles, the problem that the hanging holes or handles of the second storage bag 10 are deformed and even broken due to the fact that stress is concentrated on the point of the hanging hooks 7 is avoided.

Further, when the weight of the article to be frozen is light, even if it is placed in the storage bag, it cannot be frozen in the freezing liquid, and at this time, the two clips 8 which are not used may be connected by the magnet 16 as a configuration and placed in the second storage bag 10 for opening the second storage bag 10, see fig. 3C.

On the one hand, the arrangement of the magnetic block 16 can increase the clamping force, on the other hand, the counterweight is formed as a connecting piece for connecting the two clamping clips 8, so that a counterweight component is not required to be arranged separately, and the clamping clips 8 can be adsorbed on the shell of the fresh-locking machine through the arrangement of the magnetic block 16, thereby avoiding the loss caused by throwing away and avoiding separate storage.

In some embodiments, the magnet 16 is removably mounted to the clip 8, so that when the clamping force of the clip 8 is sufficient, the magnet 16 can be removed for mounting to another clip 8, i.e., even if some of the clips 8 are damaged, the magnet 16 alone can be recycled.

Referring to fig. 3C and 3D, in some embodiments, the clip 8 includes a first clip and second clips symmetrically disposed on both sides of the first clip such that the clip 8 has a U-shaped cross section, and the magnetic block 16 is fixedly disposed on the outside of the first clip. Of course, the magnetic block 16 may be disposed on any of the second clips.

In some embodiments, a plurality of second storage bags 10 may be held on each first support bar 61. Of course, each second storage bag 10 may also be held by one clip 8 or two or more clips 8, and specifically may be adjusted according to the width of the second storage bag 10 and the weight of the articles contained therein.

In some embodiments, a plurality of hooks 7 may be fixed on the placement frame 5, two placement frames 5 are respectively placed in two mounting grooves 4, a plurality of sliding blocks are arranged at the bottom of the placement frame 5, a sliding groove is formed in the mounting groove 4, and the sliding blocks are all slidingly connected in the sliding groove.

In some embodiments, the opening of the second storage bag 10 is provided with a clip chain 14 capable of being pressed and sealed, after the article is placed in the second storage bag 10, the clip chain 14 can be pressed and sealed, and then the hanging area 101 at the opening of the clip chain is covered on the first supporting rod 61 and fixed by the clip 8, so that double sealing is realized, and freezing liquid is prevented from splashing into the bag during the running process of the vehicle.

In some embodiments, the first support bar 61 includes a first bar 611, a second bar 612, and a third bar 613 connected in sequence, and suspension areas are provided on each of the first bar 611, the second bar 612, and the third bar 613. The hanging area here is the area that is in surface contact with the second storage bag 10 and also in surface contact with the clip 8.

Of course, further, the first support rod 61 may also be provided with a hook 7 for hanging the storage bag, see fig. 2C-2E.

Of course, further, in order to avoid sliding of the mounting frame assembly in the mounting groove 4 during running of the vehicle, corresponding limiting members may also be provided in the mounting groove 4. In some embodiments, the limiting component may adopt a magnetic block 16 detachably mounted on the above-mentioned clip 8, after the mounting frame 5 is mounted, the magnetic block 16 on the clip 8 is removed, and then the two sides of the mounting frame attached to the inner wall of the fresh-locking machine are respectively attached with the magnetic blocks 16, so as to limit the fresh-locking machine. Of course, a recess may be provided directly inside the mounting groove 4 for positioning.

If the first support rod 61 is in a telescopic state, during use, the placing frame 5 is manually compressed to enable the first support rod 61 to gradually shrink, then the first support rod 61 is placed in the two mounting grooves 4 of the fresh-locking machine body 2, so that the mounting frame assembly for hanging articles is mounted in the fresh-locking machine body 2, and then the second storage bag 10 filled with articles is hung on the first support rod 61 by means of the U-shaped clamp 8, so that most of the second storage bag 10 is immersed in food-grade refrigerating fluid in the fresh-locking machine body 2 for fresh preservation. For easy access, the main cabinet 3 is directed to the vehicle cab side, and the cover 1 is opened toward the vehicle tail to facilitate access to the articles.

If the weight of the articles in the second storage bag 10 is light, for example, a lettuce, the second storage bag 10 cannot be immersed in the freezing liquid because of the high density of the freezing liquid, at this time, only two clips 8 which are not used are required to be absorbed together through the magnetic blocks 16, then placed in the second storage bag 10, the lettuce is placed in the second storage bag, and finally the second storage bag 10 is clamped on the first staff by using the clips 8. Of course, since lettuce is light in weight, even without the weight of the magnet 16 or the clamping of magnetic force, it can clamp the second storage bag 10 on the first support bar 61, and thus the magnet 16 making the counterweight can be directly removed from the two clips 8 and mounted on the other two clips 8 without the magnet 16. Because the inner walls of the new plastic bag with electrostatic function can be adsorbed together, the width of the two clamping clips 8 can open the storage bag to a certain extent by a certain width, and then the objects can be directly put into the storage bag. And the operations such as blowing air into the storage bag and the like are not needed.

The invention further provides another fresh-locking machine.

The fresh-keeping machine of the present embodiment includes the respective components of the first embodiment, except that, for the lighter weight articles, a third storage bag 11 is separately provided, the bottom of the third storage bag 11 is provided with a counterweight 13, and the third storage bag 11 is provided with a hanging hole for hanging, see fig. 4, and at the same time, at least one second support rod 62 parallel to the first support rod 61 is further provided, and the second support rod 62 is further provided with a plurality of hooks 7 matching with the hanging hole, see fig. 2B to 2E.

In some embodiments, the second support bar 62 includes a fourth bar 621, a fifth bar 622, and a sixth bar 623 connected in sequence, wherein a plurality of hooks 7 are disposed on the fourth bar 621 and the sixth bar 623 at intervals, and one hook 7 is disposed in the middle of the fifth bar 622.

Preferably, the mounting assembly includes two first support bars 61 and one second support bar 62.

The main control board is arranged in the main machine box and is used for matching pre-stored optimal fresh-keeping time (which can be obtained through experiments in advance and is not repeated here) in the database according to the type or the name of the article input by the user, and starting timing from the situation that the user puts the corresponding article in the fresh-keeping machine body 2 and closes the machine cover, and triggering the interaction module to remind that the fresh-keeping time is reached if the timing reaches the matched optimal fresh-keeping time.

Of course, the voice module can be further arranged, so that when the timing reaches the matched optimal fresh-keeping time, the main control board triggers the voice module to remind that the fresh-keeping time is reached.

Furthermore, a wireless communication module can be further arranged, so that when the timing reaches the matched optimal fresh-keeping time, the main control board sends a message to the mobile terminal of the user through the wireless communication module to prompt that the fresh-keeping time is reached. Preferably, the message is sent when it is detected that the user has not taken out the item after a preset time threshold has elapsed after prompting by the voice module.

Specifically, whether the user takes out the corresponding item is detected, and whether the item category or name is deleted from the fresh list by the user is detected.

In other embodiments, a detection device may be provided on the fresh-locking machine body, for identifying the articles placed in or taken out of the fresh-locking machine, so as to realize automatic detection. Of course, this increases the cost of the fresh machine.

Of course, the identification code is generated in advance based on the optimal fresh-keeping time of each type of articles obtained through investigation and a large number of tests, and can be directly adhered to the storage bag when being used by a user. Of course, instead of setting an identification code for each item, an identification code is generated based on the average value of items that are close in optimal fresh-keeping time (e.g., only a few minutes apart). Therefore, after the user receives the message, the user can also inquire the specific object name in the database through the mobile terminal to inquire the optimal fresh-keeping time of the object, then determine whether to continue fresh-keeping according to the inquired optimal fresh-keeping time, if so, set the duration of continuing fresh-keeping through the mobile terminal, send to the main control board through the wireless network to control the main control board to restart timing, and remind again when the timing is up. Of course, if no preservation is required, the user goes to take out the article. Of course, if the fresh-keeping article in the fresh-keeping machine only has the article, the mobile terminal can directly send a shutdown instruction to the main control board.
