Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0029] Combination Figures 1-3 An easy-to-clean ultra-low temperature quick-freezing cabinet includes a quick-freezing cabinet body 1 and a sliding frame 2 slidably connected to one side of the quick-freezing cabinet body 1, and a protective door 3 rotatably connected to one side of the sliding frame 2. The quick-freezing cabinet body 1 is provided with a separation mechanism, which is used to facilitate the cleaning of the inner wall of the quick-freezing cabinet body 1 by the staff. The separation mechanism includes a motor 11 fixedly connected to the inside of the quick-freezing cabinet body 1. A sealing block 12 is also fixedly connected to one side of the quick-freezing cabinet body 1, and a sealing ring gasket 31 is fixedly connected to the inner side of the sliding frame 2.
[0030] The present invention will be further described below with reference to the embodiments.
[0031] Example 1:
[0032] To address the problem that existing ultra-low temperature blast freezers typically require heating elements for defrosting during cleaning, but the low internal temperature of the freezer can easily damage these elements, hindering cleaning of the rear inner wall of the freezer, this embodiment discloses the following technical solution, specifically as follows: Figures 1-3 As shown, a transmission screw 111 is fixedly connected to the output end of the motor 11. A sliding block 112 is threadedly connected to the outer side of the transmission screw 111. The sliding block 112 is fixedly connected to the sliding frame 2. A transmission wheel 21 is fixedly connected to the bottom of the sliding frame 2, and the transmission wheel 21 is in contact with the ground. A placement groove 13 is provided at the bottom of the blast freezer body 1. The sliding block 112 is slidably connected inside the placement groove 13. A sealing groove 22 is provided on the other side of the sliding frame 2, and the sealing groove 22 is slidably engaged with the sealing block 12. When it is necessary to clean the rear inner wall of the blast freezer body 1 after a period of use, the cooling system of the device can be de-energized. After a period of time, the device can be re-energized. The internal motor 11 drives the transmission screw 111 to rotate, which in turn causes the sliding block 112 to slide inside the placement groove 13. At this time, the sliding frame 2 can slide. The sliding frame 2 can move stably through the bottom transmission wheel 21, so that the sliding frame 2 can separate from the freezer body 1, which makes it convenient for the staff to clean the rear inner wall of the freezer body 1. When it is necessary to reset the sliding frame 2, the motor 11 can be started in reverse, so that the sliding frame 2 overlaps with the freezer body 1. The sealing block 12 and the sealing groove 22 can further improve the sealing performance of the device, which realizes the function of making it convenient for the staff to clean the rear inner wall of the freezer body 1, thus improving the use effect.
[0033] Example 2:
[0034] To address the problem that existing ultra-low temperature quick-freezing cabinets are often inconvenient for operators to adjust according to the size of the stored items, requiring either compressing the items or selecting a larger quick-freezing cabinet, this embodiment discloses the following technical solution, specifically as follows: Figure 3 and Figure 4 As shown, the protective door 3 matches the sealing ring gasket 31. A fixed frame 23 is fixedly connected inside the sliding frame 2, and multiple sets of fixed frames 23 are provided. A placement tray 24 is detachably installed inside the fixed frame 23. A connecting groove 231 is opened on the inner side of the fixed frame 23. Connecting blocks 241 are fixedly connected to both ends of the placement tray 24. The connecting blocks 241 slide in conjunction with the connecting groove 231. A magnetic block 242 is fixedly connected to one end of the connecting block 241. A second magnetic block 243 is fixedly connected inside the fixed frame 23. The magnetic properties of the second magnetic block 243 are opposite to those of the first magnetic block 242. A friction pad 244 is fixedly connected inside the placement tray 24. When it is necessary to store items, the protective door 3 can be opened. If necessary, the placement tray 24 can be removed from the fixing frame 23 and the items can be placed on the remaining placement trays 24. When it is necessary to install the placement tray 24, the connecting blocks 241 at both ends of the placement tray 24 can be aligned with the connecting grooves 231 on the fixing frame 23 and inserted. At this time, due to the setting of magnetic block 1 242 and magnetic block 243, the placement tray 24 will not slide inside the fixing frame 23. The setting of the friction pad 244 inside the placement tray 24 can prevent the items from sliding around on the placement tray 24, thus facilitating the storage of items. The setting of the sealing ring gasket 31 can improve the airtightness of the protective door 3, realizing the function of adjusting the storage space inside the sliding frame 2 according to the actual situation, which is convenient for use.
