Description

Technical Field

[0001] This utility model relates to the field of freezers, and in particular to a cleaning device for air-cooled freezers. Background Technology

[0002] A freezer, also called a refrigerator, is a device used to preserve food and other items at low temperatures. The basic function of a freezer is refrigeration, maintaining a suitable low temperature inside. A refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary tube or thermostatic expansion valve, and an evaporator.

[0003] When freezers are in actual use, the door is frequently opened, and outside air carrying water vapor enters the freezer. During the subsequent cooling process, ice will form on the inner wall of the freezer, which will affect the actual storage space of the freezer over time. Therefore, an air-cooled freezer cleaning device is designed. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a cleaning device for air-cooled freezers. It solves the technical problem that, during actual use, frequent opening of the freezer door allows external air containing water vapor to enter, causing ice to form on the inner walls of the freezer during subsequent refrigeration, which over time reduces the actual storage space of the freezer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling freezer cleaning device includes a cabinet body and a cabinet door movably connected to the upper side of the cabinet body; It also includes a frame set inside the cabinet, with multiple arc-shaped bladders evenly laid on the inner wall of the frame, and an annular strip fitted on the outer wall of the frame. The annular strip has a notch, the position of which corresponds to the position of the air cooler fixedly installed on the cabinet. Additionally, a connecting block is fixedly connected to the cabinet door. When the cabinet door rotates relative to the cabinet body, the connecting block contacts a trigger switch set on the outer wall of the cabinet body, causing the baffle at the notch to open, allowing the air from the evaporator to enter the arc-shaped bladder.

[0006] Preferably, it also includes a sleeve fixedly installed on the outer wall of one side of the cabinet door, and a rotating shaft fixedly installed on the outer wall of the upper side of the cabinet body. The sleeve is fitted onto the outer wall of the rotating shaft and is rotatably connected to the rotating shaft.

[0007] Preferably, it also includes an annular groove formed in a ring shape on the outer side of the frame, the inner wall of the annular groove being connected and fixed to the outer wall of the annular strip, and a plurality of connecting holes formed on the inner wall of the annular groove, the connecting holes being in communication with the inner wall of the arc-shaped bladder.

[0008] Preferably, it also includes a vertical groove formed on the outer wall of the frame, and a first electromagnet is laid on the inner wall of the vertical groove; The baffle is movably connected in the vertical groove, and a first magnetic block is fixedly installed on the upper outer wall of the baffle. When the first electromagnet is energized, the first magnetic block and the first electromagnet are magnetically attracted to each other. When the overlapping block contacts the trigger switch, the first electromagnet is energized, and the corresponding baffle will slide upward in the vertical groove, making the notch open.

[0009] Preferably, it also includes multiple through slots in a ring structure on the bottom surface of the frame, and a movable plate movably connected to the bottom surface of the frame. The movable plate has through slots and a second magnetic block fixedly installed on the upper end of the movable plate. The second magnetic block slides in conjunction with a sliding groove in the middle of the bottom surface of the frame, and a second electromagnet is fixedly installed on the bottom surface of the sliding groove. When the second electromagnet is energized, the second electromagnet and the second magnetic block are magnetically attracted to each other. When the overlapping block contacts the trigger switch, the second electromagnet is energized. Under the magnetic attraction between the second electromagnet and the second magnetic block, the corresponding second magnetic block will slide in the groove, so that the through groove and the through slot are aligned.

[0010] Preferably, it also includes a collection frame that is movably connected to the bottom of the cabinet, and a drain pipe is provided on one side of the collection frame. Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a ring-shaped belt and an arc-shaped bladder. When the freezer is opened and in use, the rotation of the door causes the arc-shaped bladder to deform, effectively cleaning the frost that has condensed on the inner wall of the frame. At the same time, a collection frame located on the lower side of the frame can collect and process the cleaned frost. Attached Figure Description

Example

[0018] See attached document Figures 1-3 As shown, a cooling freezer cleaning device includes a cabinet body 100 and a cabinet door 200 movably connected to the upper side of the cabinet body 100. The cabinet body 100 and the cabinet door 200 are conventional structural settings for freezers and will not be described in detail in this application. Furthermore, in this application, the cleaning device designed in the freezer is activated by the rotation of the angle between the cabinet door 200 and the cabinet body 100. Specifically, this application also includes a frame 300 located inside the cabinet 100, with multiple arc-shaped bladders 310 evenly distributed on the inner wall of the frame 300, and an annular strip 400 fitted on the outer wall of the frame 300. The annular strip 400 has a notch 401, the position of which corresponds to the position of the air cooler fixedly installed on the cabinet 100; and an overlapping block 220 fixedly connected to the cabinet door 200. When the cabinet door 200 rotates relative to the cabinet 100, the overlapping block 220 contacts the trigger switch 110 located on the outer wall of the cabinet 100, causing the baffle 410 at the notch 401 to open, allowing the air cooler to enter the arc-shaped bladders 310. Specifically, the cleaning method mentioned in this application involves multiple arc-shaped bladders 310 installed on the inner wall of the frame 300. In the actual cleaning process, since the arc-shaped bladders 310 are made of rubber, when a certain amount of gas is injected into the arc-shaped bladders 310, the arc-shaped bladders 310 will deform. Through this deformation, when the moisture in the external water vapor condenses on the outer wall of the arc-shaped bladders 310, the deformation of the arc-shaped bladders 310 can remove the solidified frost from the arc-shaped bladders 310 and drop it to the bottom of the frame 300.

[0019] Specifically, this application also includes a sleeve 210 fixedly installed on one side of the outer wall of the cabinet door 200, and a rotating shaft 120 fixedly installed on the upper outer wall of the cabinet body 100. The sleeve 210 is fitted onto the outer wall of the rotating shaft 120 and is rotatably connected to the rotating shaft 120. When the cabinet door 200 needs to be opened, the sleeve 210, which is fixedly connected to the cabinet door 200, will also rotate synchronously. In conjunction with the rotatable connection between the sleeve 210 and the rotating shaft 120, the sleeve 210 and the cabinet door 200 will rotate relative to the rotating shaft 120.

[0020] In one embodiment, this application also includes an annular groove 301 formed in a ring shape on the outer side of the frame 300. The inner wall of the annular groove 301 is connected and fixed to the outer wall of the annular strip 400. Multiple connecting holes 302 are formed on the inner wall of the annular groove 301, and the connecting holes 302 communicate with the inner wall of the arc-shaped bladder 310. It also includes a vertical groove formed on the outer wall of the frame 300. A first electromagnet 330 is laid on the inner wall of the vertical groove. A baffle 410 is movably connected within the vertical groove, and a first magnetic block 411 is fixedly installed on the upper outer wall of the baffle 410. When the first electromagnet 330 is energized, the first magnetic block 411 and the first electromagnet 330 are magnetically attracted to each other. When the overlapping block 220 contacts the trigger switch 110, the first electromagnet 330 is energized, and the corresponding baffle 410 slides upward within the vertical groove, causing the notch 401 to be in an open state.

[0021] Specifically, when the cabinet door 200 is open, the overlapping block 220, which is fixedly connected to the sleeve 210, will rotate synchronously. When the cabinet door 200 is open and in a fixed position, the overlapping block 220 will contact the trigger switch 110 on the outer wall of the cabinet 100. When the trigger switch 110 is open, the first electromagnet 330, which is installed in the vertical groove, will be energized and become magnetic. Combined with the magnetic attraction between the first electromagnet 330 and the first magnetic block 411, it can drive the sliding connection on the annular strip 4 When the baffle 410 at the notch 401 on the upper part moves upward, the annular groove 301 between the annular strip 400 and the middle of the frame 300 remains connected to the interior of the cabinet 100. A cold air fan is installed on one side of the cabinet 100, and the position of the notch 401 corresponds to the position of the cold air fan. At this time, the cold air blown out by the cold air fan will enter the annular groove 301 and enter the interior of the arc-shaped bladder 310 through the connecting hole 302, thereby causing the arc-shaped bladder 310 to deform, thereby causing the frost condensed on its outer wall to break and fall to the bottom of the frame 300.

[0022] As one implementation method, as mentioned above, when the cabinet door 200 is opened, the corresponding arc-shaped bladder 310 will deform, causing the frost on the surface of the arc-shaped bladder 310 to break and fall to the bottom of the frame 300. In order to ensure the storage space inside the frame 300, the frost that has been cleared out needs to be collected and cleaned. Specifically, in this application, it also includes a plurality of through slots 303 in a ring structure on the bottom surface of the frame 300, and a movable plate 500 movably connected to the bottom surface of the frame 300. The movable plate 500 has a through slot 501, and also includes a component fixedly installed on the upper end of the movable plate 500. The second magnetic block 510 slides in a groove 304 located in the middle of the bottom surface of the frame 300. A second electromagnet 320 is fixedly installed on the bottom surface of the groove 304. When the second electromagnet 320 is energized, it magnetically attracts the second magnetic block 510. When the overlapping block 220 contacts the trigger switch 110, the second electromagnet 320 is energized. Under the magnetic attraction between the second electromagnet 320 and the second magnetic block 510, the second magnetic block 510 slides in the groove 304, aligning the through groove 501 with the through slot 303.

[0023] Specifically, when the cabinet door 200 is open, the corresponding trigger switch 110 is also open, which energizes the second electromagnet 320 and magnetically attracts it to the second magnetic block 510. It should be noted that when the moving plate 500 is in its original position, the second magnetic block 510 and the second electromagnet 320 are misaligned. When the second electromagnet 320 is energized, it will move the moving plate 500 at the bottom of the frame 300, and make the originally misaligned through groove 501 and through groove 303 aligned, so that the frost at the bottom of the frame 300 can fall to the lower side of the frame 300.

[0024] Furthermore, this application also includes a collection frame 600 movably connected to the bottom of the cabinet 100. A drain pipe 610 is also provided on one side of the collection frame 600. The collection frame 600 is movably connected to the lower bottom of the cabinet 100 and maintains a movable connection with the cabinet 100. When a certain amount of frost is collected on the collection frame 600, the collection frame 600 can be pulled out and cleaned up.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
