Description

Technical Field

[0001] The utility model belongs to the field of dust covers, and specifically relates to a dust cover for an air-cooled refrigeration device. Background Technique

[0002] Air cooling is a cooling method. The most common air-cooled refrigeration device in life is popular among people because of its good refrigeration effect and wide application range. Dust is easy to enter the interior of the air-cooled refrigeration device through the air inlet. When not in use for a long time, dust may also enter the interior of the air-cooled refrigeration device through the air outlet, affecting the working efficiency of the device. Therefore, it is necessary to install a dust cover at the air outlet of the air-cooled refrigeration device. The patent with the authorization announcement number CN216814764U: "A Dust Cover for an Air-Cooled Refrigeration Device" discloses a device for dust prevention of an air-cooled refrigeration device. However, when cleaning the dust on the filter screen in this device, the operator needs to hold the handle to drive the cleaning brush to move up and down. At the same time, it is also necessary to start the driving motor, and the driving motor drives the cam to rotate, and the cam drives the filter screen to move up and down to remove the dust on the filter screen. This device requires manual operation, which is time-consuming and laborious, and requires motor drive, increasing the cost. Therefore, we designed a dust cover for an air-cooled refrigeration device that can automatically clean the dust on the filter screen. Content of the Utility Model

[0017] An air-cooled refrigeration equipment dust cover, as shown in Figure 1 、 2, as shown in Figures 3 and 4, it includes a refrigeration equipment body 1. Two strip plates 2 distributed front and back are fixedly installed at the air outlet of the refrigeration equipment body 1. The two strip plates 2 are symmetrically distributed front and back. A frame 3 is detachably arranged between the two strip plates 2. The frame 3 can cover the air outlet of the refrigeration equipment body 1. The side of the frame 3 close to the refrigeration equipment body 1 is in sliding contact and cooperation with the refrigeration equipment body 1. A filter screen 4 is fixedly installed on the inner wall of the frame 3. A plurality of vertical first dovetail chutes 5 are opened on the side of the frame 3 far from the refrigeration equipment body 1. In this embodiment, the number of the first dovetail chutes 5 is two, and the two first dovetail chutes 5 are symmetrically distributed front and back. The lower ends of the first dovetail chutes 5 are respectively communicated with the outside. First dovetail sliders 6 are respectively slidably installed in the first dovetail chutes 5. The same C-shaped plate 7 is fixedly installed on the plurality of first dovetail sliders 6. The C-shaped plate 7 includes a long plate and short plates at both ends of the long plate. The first dovetail sliders 6 are fixedly connected with the corresponding short plates of the C-shaped plate 7. A brush 8 is fixedly arranged on the side of the C-shaped plate 7 close to the filter screen 4. The long plate part of the C-shaped plate 7 is provided with the brush 8. The brush 8 is in sliding contact and cooperation with the filter screen 4. It is characterized in that: a water receiving hopper 9 is fixedly installed on the side of the C-shaped plate 7 far from the filter screen 4. First mounting plates 10 are respectively fixedly installed on the front and back sides of the refrigeration equipment body 1. Two second dovetail chutes 11 which are symmetrically distributed left and right are respectively opened on the first mounting plates 10. Second dovetail sliders 12 are respectively slidably installed in the second dovetail chutes 11. The front and back sides of the C-shaped plate 7 are sequentially fixedly connected with the two second dovetail sliders 12 on the right side through connecting rods 13. Counterweights 14 are respectively fixedly installed on the left second dovetail sliders 12. Fixed pulleys 15 are respectively rotatably installed on the upper sides of the first mounting plates 10. The two second dovetail sliders 12 on the same first mounting plate 10 are connected by a pull rope 16. The pull rope 16 passes over the corresponding fixed pulley 15 and is in frictional contact and cooperation with the fixed pulley 15. The structure of the utility model is simple and ingenious. It can automatically clean the dust on the filter screen 4 without manual operation, which saves time and effort. Moreover, it does not need to be driven by a motor, which saves costs. It can meet the market demand and is suitable for popularization.When the utility model is in use and in case of rainy weather, rainwater falls into the water receiving hopper 9. The rainwater in the water receiving hopper 9 increases. When the total weight of the water receiving hopper 9 and the rainwater in it is greater than the weight of the counterweight 14, under the action of the gravity of the water receiving hopper 9 and the rainwater, the water receiving hopper 9 moves downward. The downward movement of the water receiving hopper 9 drives the C-shaped plate 7, the brush 8, the connecting rod 13 and the second dovetail slider 12 on the right side to move downward along the corresponding second dovetail chute 11. The first dovetail slider 6 on the C-shaped plate 7 slides downward along the corresponding first chute 7. The brush 8 moves downward to remove the dust attached to the filter screen 4. The second dovetail slider 12 on the right side drives the second dovetail slider 12 on the left side and the counterweight 14 to move upward through the pull rope 16, and the fixed pulley 15 rotates. When the rain stops, as the rainwater in the water receiving hopper 9 continuously evaporates, when the total weight of the water receiving hopper 9 and the rainwater in it is less than the weight of the counterweight 14, under the action of the gravity of the counterweight 14, the counterweight 14 and the second dovetail slider 12 on the left side move downward. The counterweight 14 drives the second dovetail slider 12 on the right side to move upward through the pull rope 16. The second dovetail slider 12 on the right side drives the brush 8 and the water receiving hopper 9 to move upward through the connecting rod 13 and the C-shaped plate 7. The upward movement of the brush 8 can clean the dust attached to the filter screen 4 again. The upward movement of the water receiving hopper 9 is convenient for receiving rainwater again to drive the brush 8 to move downward.

[0018] Specifically, as shown in the figure, on the mutually close sides of the strip plates 2, third dovetail chutes 20 are respectively opened. The upper sides of the third dovetail chutes 20 are respectively communicated with the outside. Third dovetail sliders 21 are respectively slidably installed in the third dovetail chutes 20. The two third dovetail sliders 21 are sequentially fixedly connected to the front and rear sides of the frame 3. A limiting device for limiting the sliding of the third dovetail slider 21 is provided on the strip plate 2. Remove the limit of the limiting device on the third dovetail slider 21, and pull the frame 3 upward. The upward movement of the frame 3 drives the two third dovetail sliders 21 to slide along the corresponding third dovetail chutes 20. At the same time, the first dovetail chute 5 slides upward relative to the first dovetail slider 6 until the third dovetail slider 21 slides out of the corresponding third dovetail chute 20 and the first dovetail slider 6 slides out of the first dovetail chute 5. At this time, the frame 3 and the filter screen 4 can be disassembled, which is convenient for replacing the new filter screen 4. Similarly, align the third dovetail slider 21 on the frame 3 with the corresponding third dovetail chute 20, and align the first dovetail chute 5 with the corresponding first dovetail slider 6, and then move the frame 3 downward until the lower end of the third dovetail slider 21 contacts the lower end of the inner wall of the corresponding third dovetail chute 20. At this time, the installation of the frame 3 and the new filter screen 4 is completed, and then the third dovetail slider 21 is limited by the limiting device.

[0019] Specifically, as shown in the figure, the limiting device in this embodiment includes a plug rod 30. A jack 31 is provided on the inner wall of the third dovetail chute 20 corresponding to the plug rod 30. The plug rod 30 is slidably installed in the jack 31. The plug rod 30 is connected to the corresponding strip plate 2 by a first spring 32. The first spring 32 is sleeved on the outer periphery of the plug rod 30. One end of the first spring 32 is fixedly connected to one side of the strip plate 2, and the other end of the first spring 32 is fixedly connected to the outer periphery of the plug rod 30. A slot 33 is provided on the third dovetail slider 21 corresponding to the plug rod 30. The plug rod 30, the jack 31 and the slot 33 are coaxially arranged. The plug rod 30 is in plug-in fit with the corresponding slot 33. Pull the plug rod 30 forward, and the first spring 32 extends until the plug rod 30 is removed from the corresponding slot 33. At this time, the plug rod 30 no longer limits the third dovetail slider 21, and the third dovetail slider 21 can be removed from the corresponding third dovetail chute 20. Similarly, slide the third dovetail slider 21 into the corresponding third dovetail chute 20. When the jack 31 is aligned with the slot 33, under the elastic force of the first spring 32, the plug rod 30 is in plug-in fit with the slot 33 to limit the third dovetail slider 21.

[0020] Further, as shown in the figure, a drain pipe 40 is connected and installed at the lower end of the water receiving hopper 9 in this embodiment. The opening at the lower end of the drain pipe 40 is larger than the opening at the upper end of the drain pipe 40. A moving plate 41 is installed in the inner wall of the upper end of the drain pipe 40 in an airtight sliding fit manner. A vertical rod 42 is fixedly installed on the upper side of the moving plate 41. A coaxial circular ring 43 is installed in a sliding fit manner on the outer circumference of the vertical rod 42. The circular ring 43 is fixedly installed on the inner wall of the drain pipe 40. A second spring 44 is connected between the vertical rod 42 and the circular ring 43. The second spring 44 is sleeved on the outer circumference of the vertical rod 42. One end of the second spring 44 is fixedly connected to the outer circumference of the vertical rod 42, and the other end of the second spring 44 is fixedly connected to one side of the circular ring 43. The rainwater in the water receiving hopper 9 flows into the upper part of the moving plate 41. As the rainwater increases, under the action of the gravity of the rainwater, the moving plate 41 moves downward, the vertical rod 42 slides downward along the circular ring 43, and the second spring 44 is compressed. Since the moving plate 41 moves downward, the cavity formed by the water receiving hopper 9, the drain pipe 40 and the moving plate 41 becomes larger and larger, and the rainwater in the water receiving hopper 9 becomes more and more. When the weight of the water receiving hopper 9 and the rainwater is greater than the weight of the counterweight 14, the water receiving hopper 9 drives the second dovetail slider 12 on the right side to move downward through the C-shaped plate 7, and then drives the brush 8 to move downward, so as to remove the dust on the filter screen 4. The second dovetail slider 12 on the right side moves downward to drive the second dovetail slider 12 and the counterweight 14 on the left side to move upward through the pull rope 16. When the moving plate 41 moves downward to the lower end of the drain pipe 40, the outer wall of the moving plate 41 is not in airtight sliding contact with the inner wall of the lower end of the drain pipe 40, and the rainwater in the water receiving hopper 9 flows out through the gap between the moving plate 41 and the inner wall of the lower end of the drain pipe 40. As the rainwater in the water receiving hopper 9 becomes less, the moving plate 41 moves upward under the elastic force of the second spring 44, and the outer wall of the moving plate 41 is again in airtight sliding contact with the inner wall of the upper end of the drain pipe 40. Since the rainwater in the water receiving hopper 9 becomes less, the weight of the water receiving hopper 9 and the rainwater is less than the weight of the counterweight 14. Therefore, under the action of the gravity of the counterweight 14, the second dovetail slider 12, the C-shaped plate 7, the brush 8, the water receiving hopper 9 and the drain pipe 40 gradually move upward. After the remaining rainwater in the water receiving hopper 9 is completely evaporated, under the action of the gravity of the counterweight 14, the C-shaped plate 7, the brush 8, the water receiving hopper 9 and the drain pipe 40 move upward to reset.

[0021] Further, as shown in the figure, second mounting plates 50 are respectively fixedly installed on the upper and lower sides of the refrigeration equipment body 1 in this embodiment. Mounting holes 51 are respectively formed in the second mounting plates 50. The refrigeration equipment body 1 is conveniently installed on the wall through the mounting plates 50 and the mounting holes 51.

[0022] Further, as shown in the figure, a first baffle 60 is fixedly installed at the upper end of the vertical rod 42 in this embodiment. The first baffle 60 is used to prevent the vertical rod 42 from sliding out of the circular ring 43.

[0023] Further, as shown in the figure, one end of the insertion rod 30 in this embodiment is fixedly installed with a second baffle 70. It is more convenient and labor-saving to pull the insertion rod 30 through the second baffle 70.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
