[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0033] Example 1: A vertical intelligent refrigerator with zoned temperature control, see Figure 1-Figure 11 , including a refrigerating cabinet body 1, a refrigerator 2, a cabinet door 21, a storage box 3, a connecting pipe 4, a sealing box 5, a cooling pipe 6, a sliding plate 7, a coil spring 73, a rotating rod 8, a turntable 9, a fixing ring 91 and a driving assembly. A groove is provided at the lower part of the refrigerating cabinet body 1, a plurality of round holes 72 are opened at the left part of the refrigerating cabinet body 1, a refrigerating machine 2 is installed above the refrigerating cabinet body 1, a filter is provided at the upper part of the refrigerating machine 2, two cabinet doors 21 are installed at the right part of the refrigerating cabinet body 1, the groove is located directly below the cabinet door 21, a storage box 3 is fixedly connected to the upper left side of the refrigerating cabinet body 1, the storage box 3 is connected to the refrigerating machine 2, a sealing box 5 is fixedly connected to the left side of the refrigerating cabinet body 1, and the sealing box 5 and the storage box 3 are connected. There are two connecting pipes 4 fixedly connected in between, a cooling pipe 6 is installed on the left side of the refrigerating cabinet 1, and the cooling pipe 6 is connected to the refrigerator 2. Four sliding plates 7 are slidably connected to the left side of the refrigerating cabinet 1. The front of the sliding plate 7 is set as an inclined surface. Two coil springs 73 are fixedly connected between the sliding plate 7 and the refrigerating cabinet 1. There are air outlet holes 71 on the sliding plate 7. When the sliding plate 7 slides backward, the air outlet holes 71 will be aligned with the adjacent circular holes 72. A rotating rod 8 is rotatably connected to the front of the refrigerating cabinet 1. A plurality of turntables 9 are fixedly connected to the rotating rod 8. A fixing ring 91 is fixedly connected to the upper part of the turntable 9. The remaining area cut by the fixing ring 91 of the turntable 9 from top to bottom is getting larger and larger. Please refer to Figure 4 The rotation of the fixed ring 91 will squeeze the sliding plate 7. The time for which the fixed ring 91 with different remaining cutting areas squeezes the sliding plate 7 is different. The larger the remaining cutting area of ​​the fixed ring 91, the longer the time for squeezing the sliding plate 7, and thus the longer the time for the air outlet 71 and the circular hole 72 to be aligned, thereby making the temperature in this area lower. A driving component for driving the rotating rod 8 to rotate is provided on the storage box 3.

[0034] See also Figure 1 , Figure 2 and Figure 4The driving assembly includes an airbag 101, a rack 102 and a gear 103. The airbag 101 is arranged in the storage box 3. The rack 102 is fixedly connected to the front of the airbag 101. The gear 103 is arranged on the upper part of the rotating rod 8. The gear 103 is connected to the rotating rod 8 through a one-way clutch. The rack 102 passes through the storage box 3 and meshes with the gear 103.

[0035] Turn on the refrigerator 2, so that the cold air enters the storage box 3 and the cooling pipe 6. The cooling pipe 6 contacts the refrigerating cabinet body 1, and the cooling pipe 6 can directly cool the refrigerating cabinet body 1. The cold air enters the storage box 3 and enters the sealed box 5 through the connecting pipe 4. The cold air enters the storage box 3 and enters the airbag 101 at the same time, thereby expanding the airbag 101. The expansion of the airbag 101 will cause the rack 102 to move forward, and the forward movement of the rack 102 will drive the gear 103 to rotate. The rotation of the gear 103 will drive the rotating rod 8 to rotate. The rotation of the rotating rod 8 will drive the turntable 9 and the fixed ring 91 to rotate together. The rotation of the fixed ring 91 will squeeze the sliding plate 7. Since the front part of the sliding plate 7 is an inclined surface, the sliding plate 7 slides backward, the spiral spring 73 is compressed, and the sliding plate 7 slides backward, thereby aligning the air outlet 71 thereon with the circular hole 72 on the left part of the refrigerating cabinet body 1. At this time, the cold air will enter the refrigerating cabinet from the sealed box 5. Then the refrigerator is cooled for the second time. Since the remaining area cut by the fixing ring 91 of the turntable 9 becomes larger and larger from top to bottom, the time for the air outlet 71 of the sliding plate 7 to be aligned with the circular hole 72 becomes longer and longer from top to bottom, so that more cold air enters the lower part of the refrigerator and less cold air enters the upper part. When the fixing ring 91 rotates one circle and returns to its original position, the fixing ring 91 will not squeeze the sliding plate 7 at this time, and the spiral spring 73 is restored, so that the sliding plate 7 moves forward and returns to its original position. At the same time, the different speeds of the refrigerator 2 are controlled so that the gear 103 can rotate different numbers of circles, thereby adjusting the different cold air intake volumes as a whole, thereby achieving different temperatures in different areas of the same refrigerator, so that different foods can be preserved. There is no need to adjust multiple fans or perform temperature compensation through a heating device, so that the zoned temperature-controlled refrigerator does not require a complex structure, thereby reducing equipment costs and making temperature control and adjustment easier.

[0036] When refrigeration is not needed, the refrigerator 2 is turned off, and cold air no longer enters the storage box 3 and the airbag 101. At this time, the airbag 101 automatically recovers under the action of elastic force, thereby driving the rack 102 to move backward and return to its original position, thereby reversing the gear 103. Since the gear 103 is connected to the rotating rod 8 through a one-way clutch, the reversal of the gear 103 will not drive the rotating rod 8 to rotate, thereby ensuring the normal temperature control next time.

[0037] Example 2: Based on Example 1, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7, also includes a transmission wheel 111, a transmission belt 112 and a latching tooth 113. The transmission wheel 111 is fixedly connected to the middle of the refrigerator 2, and the front and rear sides of the upper part of the refrigerator 2 are rotatably connected to the transmission wheels 111. The three transmission wheels 111 are transmitted through the transmission belt 112, and two latching teeth 113 are provided on the transmission belt 112.

[0038] See also Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 , also includes a scraping mechanism, the scraping mechanism includes a rotating wheel 114, a rotating rod 115, a scraper 116, a reset spring 117 and a pull rope 118, the left part of the cabinet door 21 is slidably connected with a scraper 116, the scraper 116 can scrape off the water droplets on the cabinet door 21, and then make the water droplets fall into the groove, the scraper 116 and the cabinet door 21 are fixedly connected with a reset spring 117, the front and rear sides of the right part of the refrigeration cabinet 1 are rotatably connected with the rotating rod 115, the rotating rod 115 and the adjacent scraper 116 are fixedly connected with a pull rope 118, the upper part of the rotating rod 115 is fixedly connected with a rotating wheel 114, and the locking teeth 113 on the transmission belt 112 will engage with the adjacent rotating wheel 114 when rotating.

[0039] When the refrigerator 2 is turned on, the transmission wheel 111 on the refrigerator 2 will rotate, and then the transmission effect of the transmission belt 112 will cause the other two transmission wheels 111 to rotate together, so that the latch teeth 113 on the transmission belt 112 move together, and the movement of the latch teeth 113 will drive the rotating wheel 114 to rotate, so that the rotating rod 115 rotates, and the rotation of the rotating rod 115 will circle the pull rope 118, and the pull rope 118 will pull the scraper 116, so that the two scrapers 116 slide away from each other, and the return spring 117 is compressed, and the scraper 116 moves. The water drops on the cabinet door 21 can be scraped off into the groove, thereby ensuring that the cabinet door 21 is clean, and then it is convenient for people to take out the food in the refrigerator. The latch tooth 113 continues to move and separates from the rotating wheel 114. At this time, the reset spring 117 recovers, and then the two scrapers 116 slide towards each other to return to their original positions. At this time, the scraper 116 pulls the pull rope 118, so that the pull rope 118 is stretched, and then the rotating rod 115 is reversed. The reversal of the rotating rod 115 can drive the rotating wheel 114 to reverse and return to its original position.

[0040] See also Fig.10 and Fig.11, also includes a water removal mechanism, the water removal mechanism includes a scraper block 121, a moving plate 122, a buoyancy ball 123, a connecting rod 124, a sealing block 125 and a compression spring 126, the scraper block 121 is fixedly connected to the lower part of the scraper plate 116, the scraper block 121 slides in the groove, the scraper block 121 is slidably connected to the moving plate 122, the buoyancy ball 123 is installed at the lower part of the moving plate 122, the front and rear parts of the refrigeration cabinet 1 are slidably connected to the sealing block 125, the connecting rod 124 is fixedly connected to the sealing block 125, and the compression spring 126 is fixedly connected between the sealing block 125 and the refrigeration cabinet 1.

[0041] When the two scrapers 116 slide in the direction away from each other, the scraper block 121 will be driven to slide in the groove, and the scraper block 121 can then clean the water droplets scraped off in the groove. When the scraper block 121 continues to slide in the groove following the scraper 116, the scraper block 121 will contact and squeeze the connecting rod 124, so that the two connecting rods 124 move in the direction away from each other, and then the two sealing blocks 125 also move in the direction away from each other. At this time, the compression spring 126 is compressed, and the water droplets in the groove can then be discharged from the refrigerator through the original position of the sealing block 125, and there is no need for manual cleaning, which saves time and effort. When there are many water drops in the groove, the scraper block 121 scrapes the water drops in the groove, and the buoyancy ball 123 moves upward under the action of buoyancy, thereby causing the moving plate 122 to move upward together. At this time, the water drops in the groove can enter the other end of the groove through the original position of the moving plate 122, thereby preventing the water drops in the groove from overflowing during scraping. When the water drops on one side of the groove decrease, the buoyancy of the water drops is less than the total gravity of the buoyancy ball 123 and the moving plate 122, and the buoyancy ball 123 and the moving plate 122 will move downward to return to their original positions. When the scraper block 121 follows the scraper plate 116 to return to its original position, the scraper block 121 no longer squeezes the connecting rod 124, and the compression spring 126 is restored, thereby causing the connecting rod 124 and the sealing block 125 to move back to their original positions, and the sealing block 125 can then keep the refrigerator in a closed space, thereby ensuring the refrigeration effect of the refrigerator.

[0042] See also Figure 1 , Figure 2 and Figure 6 , and also includes a cleaning plate 131. The cleaning plate 131 is fixedly connected to the upper part of the refrigerator 2. The cleaning plate 131 can rotate to clean the filter screen on the upper part of the refrigerator 2, thereby ensuring the normal operation of the refrigerator 2.

[0043] When the refrigerator 2 is turned on, the cleaning plate 131 will rotate together. The cleaning plate 131 will scrape the filter screen when it rotates together, thereby preventing dust from accumulating on the filter screen, thereby ensuring normal heat dissipation of the refrigerator 2 and extending the service life of the refrigerator 2.

[0044] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention.
