Description

Technical Field

[0001] The present application relates to the technical field of freeze dryers, and in particular to a small household freeze dryer. Background Art

[0002] The freeze dryer originated from vacuum freeze-drying technology in the 1820s. In the 21st century, vacuum freeze-drying technology has been widely used in fields beyond medicine, biological products, food, blood products, and active substances. The basic principle of freeze-drying is based on the three states of water. Water exists in solid, liquid, and gaseous states, which can both transition between and coexist. When water is at its triple point, water, ice, and water vapor can coexist in equilibrium. Under high vacuum conditions, the principle of sublimation is utilized to remove moisture from pre-frozen materials directly from the ice into water vapor, without melting the ice, thus achieving the purpose of freeze-drying. With the increasing focus on healthy eating, freeze-dried foods are gaining popularity among consumers because they retain their original nutritional value and taste.

[0003] Existing small household freeze dryers usually have a small volume, which results in very limited space in the internal freeze drying chamber. However, the internal storage racks of existing small household freeze dryers usually have a relatively simple structure and cannot adjust the spacing between each layer of storage space, resulting in the limited space often being difficult to be effectively and fully utilized. Therefore, in response to the above problems, a small household freeze dryer is proposed. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a small household freeze dryer that overcomes the shortcomings of the existing technology and aims to solve the problem that the storage racks inside the small household freeze dryer are usually unable to adjust the spacing between the storage spaces on each layer, making it difficult to effectively and fully utilize the already limited space.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A small household freeze dryer includes a household freeze dryer body, a group of fixed support legs are fixedly provided in the lower part of the freeze drying chamber of the household freeze dryer body, a storage rack is mounted on the fixed support legs, the storage rack includes a rack column, the rack columns are fixedly connected as a whole by a horizontal connecting rod, a rectangular groove is opened on the inner side of the rack column, a vertically arranged guide rod is fixedly provided in the rectangular groove, a plurality of sliding support frames are slidably provided on the guide rod, a storage plate is overlapped on the sliding support frame, a locking plate is fixedly connected between the horizontal connecting rods on the left and right sides, and a locking structure is fixedly provided on the left and right sides of the sliding support frame.

[0007] By adopting the above technical solution, after loosening the locking structure, the sliding support frame loses its constraint and can slide freely along the guide rod, thereby freely adjusting the distance between each holding plate, which allows the user to freely adjust the internal space layout according to the shape of the food, thereby greatly improving the utilization rate of the limited space inside the freeze-drying chamber, and after the adjustment is completed, the locking structure can be locked to fix the adjusted position.

[0008] As a preferred technical solution of the present application, the locking structure includes a threaded sliding shaft fixedly arranged on the left and right sides of the sliding support frame and a fastening nut sleeved on the end of the threaded sliding shaft and threadedly connected thereto. A sliding groove is opened in the middle of the locking plate, and the threaded sliding shaft is slidably arranged in the sliding groove.

[0009] By adopting the above technical solution, when the fastening nut is tightened to rotate it along the threaded sliding axis and away from the locking plate, the sliding support frame loses its constraint due to the disappearance of the friction between the locking plate and the fastening nut, and can thus slide freely along the guide rod, thereby enabling free adjustment of the spacing between each holding plate. When the fastening nut is tightened, a large friction is generated between the locking plate and the fastening nut, and the sliding support frame cannot continue to change its position.

[0010] As a preferred technical solution of the present application, the outer surface of the locking plate is a rough surface densely covered with protruding particles, and the inner end surface of the fastening nut is fixedly provided with a rubber pad with a rough surface.

[0011] By adopting the above technical solution, the friction between the locking plate and the fastening nut can be significantly increased, thereby improving the fixing effect of the sliding support frame and preventing it from sliding downward after being fixed.

[0012] As a preferred technical solution of the present application, through guide holes are provided at the four corners of the sliding support frame, and the aperture of the guide holes is numerically consistent with the cross-sectional diameter of the guide rod.

[0013] By adopting the above technical solution, the sliding support frame can slide up and down along the guide rod, thereby preventing the sliding support frame from shaking during the up and down sliding process.

[0014] As a preferred technical solution of the present application, a centrally arranged holding groove is provided on the upper end surface of the holding plate, and four card blocks are fixedly provided on the lower end surface of the holding plate, and when the holding plate is overlapped on the sliding support frame, the card blocks fit tightly against the inner side surface of the sliding support frame.

[0015] By adopting the above technical solution, when the holding plate is overlapped on the sliding support frame, the clamping block can prevent the holding plate from sliding back and forth through the clamping action between the clamping block and the sliding support frame.

[0016] As a preferred technical solution of the present application, the upper end surface of the fixed support leg is provided with a centrally arranged embedding groove and a fixed magnet is fixedly installed in the groove, and the lower end surface of the frame column is provided with a centrally arranged embedding groove and a positioning magnet is fixedly installed in the groove.

[0017] By adopting the above technical solution, the entire storage rack can be fixed on the fixed supporting legs by the magnetic attraction between the fixed magnets and the positioning magnets to prevent it from sliding.

[0018] As a preferred technical solution of the present application, the magnetic pole direction of the fixed magnet is opposite to the magnetic pole direction of the positioning magnet.

[0019] By adopting the above technical solution, the positioning effect can be achieved by arranging the magnetic poles in opposite directions, that is, when the fixed magnet and the positioning magnet are attracted to each other, the two ends can be aligned, otherwise repulsion will be generated and the attraction between the two cannot occur.

[0020] The beneficial effects of the present application are as follows: after loosening the locking structure, the sliding support frame loses its constraint and can slide freely along the guide rod, thereby freely adjusting the spacing between each holding plate, which allows the user to freely adjust the internal space layout according to the shape of the food, thereby greatly improving the utilization rate of the limited space inside the freeze-drying chamber, so that the already limited space can be effectively and fully utilized, and after the adjustment is completed, the locking structure can be locked to fix the adjusted position.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Reference Figure 1-3 A small household freeze dryer includes a household freeze dryer body 1. A group of fixed supporting legs 11 are fixedly provided in the lower part of the freeze drying chamber of the household freeze dryer body 1. A storage rack 2 is mounted on the fixed supporting legs 11. The storage rack 2 includes a frame column 21. The frame columns 21 are fixedly connected as a whole by a horizontal connecting rod 211. A rectangular groove 22 is opened on the inner side of the frame column 21. A vertically arranged guide rod 23 is fixedly provided in the rectangular groove 22. A plurality of sliding support frames 24 are slidably provided on the guide rod 23. A storage plate 25 is overlapped on the sliding support frame 24. The horizontal connecting rods on the left and right sides are connected. A locking plate 26 is fixedly connected between 211, and locking structures 27 are fixedly provided on the left and right sides of the sliding support frame 24. By adopting the above technical solution, after loosening the locking structure 27, the sliding support frame 24 loses its constraint and can slide freely along the guide rod 23, thereby freely adjusting the distance between each holding plate 25, which can facilitate the user to freely adjust the internal space layout according to the shape of the food, thereby greatly improving the utilization rate of the limited space inside the freeze-drying chamber, and after the adjustment is completed, the locking structure 27 can be locked to fix the adjusted position.

[0029] Reference Figure 2 The locking structure 27 includes a threaded sliding shaft 271 fixedly arranged on the left and right sides of the sliding support frame 24 and a fastening nut 272 sleeved on the end of the threaded sliding shaft 271 and threadedly connected thereto. A sliding groove 261 is opened in the middle of the locking plate 26, and the threaded sliding shaft 271 is slidably arranged in the sliding groove 261. By adopting the above technical solution, when the fastening nut 272 is screwed to make it rotate along the threaded sliding shaft 271 and move away from the locking plate 26, the friction between the locking plate 26 and the fastening nut 272 disappears, and the sliding support frame 24 loses its constraint and can slide freely along the guide rod 23, thereby realizing the free adjustment of the spacing between each storage plate 25. When the fastening nut 272 is tightened, a large friction force is generated between the locking plate 26 and the fastening nut 272, and the sliding support frame 24 cannot continue to change its position.

[0030] In particular, the outer surface of the locking plate 26 is a rough surface covered with protruding particles, and the inner end surface of the fastening nut 272 is fixed with a rubber pad with a rough surface. By adopting the above technical solution, the friction between the locking plate 26 and the fastening nut 272 can be significantly increased, thereby improving the fixing effect of the sliding support frame 24 and preventing it from sliding downward after being fixed.

[0031] Reference Figure 4 , the sliding support frame 24 is provided with through guide holes 241 at the four corners, and the aperture of the guide hole 241 is numerically consistent with the cross-sectional diameter of the guide rod 23. By adopting the above technical solution, the sliding support frame 24 can slide up and down along the guide rod 23, avoiding the sliding support frame 24 from shaking during the up and down sliding process.

[0032] Reference Figure 3-4 The upper end surface of the holding plate 25 is provided with a centrally arranged holding groove 251, and the lower end surface of the holding plate 25 is fixedly provided with four clamping blocks 252. When the holding plate 25 is overlapped on the sliding support frame 24, the clamping blocks 252 are tightly fitted with the inner side surface of the sliding support frame 24. By adopting the above technical solution, when the holding plate 25 is overlapped on the sliding support frame 24, the clamping blocks 252 can prevent the holding plate 25 from sliding back and forth through the clamping action between the sliding support frame 24.

[0033] Reference Figure 5 The upper end surface of the fixed support foot 11 is provided with a centrally arranged embedding groove 31 and a fixed magnet 32 ​​is fixedly arranged in the groove. The lower end surface of the shelf column 21 is provided with a centrally arranged embedding groove 31 and a positioning magnet 33 is fixedly arranged in the groove. By adopting the above technical solution, the storage rack 2 can be fixed to the fixed support foot 11 as a whole by the magnetic attraction between the fixed magnet 32 ​​and the positioning magnet 33 to prevent it from sliding. In particular, the magnetic pole direction of the fixed magnet 32 ​​is opposite to the magnetic pole direction of the positioning magnet 33. This structural form can play a positioning role by arranging the magnetic poles in opposite directions, that is, when the fixed magnet 32 ​​and the positioning magnet 33 are attracted to each other, the two ends can be aligned, otherwise a repulsive force will be generated so that the adsorption effect between the two cannot occur.

[0034] Working principle: When the fastening nut 272 is tightened to rotate along the threaded sliding shaft 271 and away from the locking plate 26, the friction between the locking plate 26 and the fastening nut 272 disappears, and the sliding support frame 24 loses its constraint and can slide freely along the guide rod 23. The sliding support frame 24 can be dragged up and down by hand, thereby freely adjusting the spacing between each sliding support frame 24 to achieve the division and arrangement of the internal storage space; when the adjustment is completed, the fastening nut 272 is tightened, and a large friction force is generated between the locking plate 26 and the fastening nut 272. At this time, the sliding support frame 24 cannot continue to change its position, and then the entire storage rack 2 is placed in the freeze-drying chamber, so that the fixing magnet 32 ​​and the positioning magnet 33 are attracted to each other, thereby achieving the fixing of the storage rack 2 as a whole on the fixed support foot 11 to prevent it from sliding; finally, the storage plate 25 is overlapped on the sliding support frame 24, and the clamping block 252 on it can prevent the storage plate 25 from sliding back and forth by the clamping action with the sliding support frame 24.

[0035] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
