Description

Technical Field

[0001] This utility model relates to the field of commercial refrigeration equipment technology, and in particular to a commercial freezer display cabinet with automatic defogging function. Background Technology

[0002] The core function of commercial frozen display freezers is to effectively freeze and clearly display refrigerated goods. Their doors are usually made of transparent glass so that consumers can see the internal display directly. However, due to the significant temperature difference between the low temperature environment inside the freezer and the high temperature and humidity outside, water vapor in the environment is very easy to condense into fog or even frost on the inner surface of the glass, which seriously affects transparency, reduces the visibility of goods, and weakens the display effect.

[0003] Most existing freezers rely on manual periodic wiping of the glass to remove fog. Manual cleaning is inconvenient and incomplete, which not only increases maintenance costs and manpower burden, but also causes fog to reappear during cleaning intervals, resulting in inconsistent display quality and difficulty in maintaining clarity. This is especially true during peak hours, when it is difficult to handle the situation in a timely manner, affecting user experience and sales efficiency.

[0004] Therefore, it is necessary to design a commercial freezer display cabinet with automatic defogging function. Utility Model Content

[0005] In order to overcome the shortcomings of existing methods that rely on manual defogging, which is time-consuming and labor-intensive, and whose repeated fogging leads to unstable display effects and difficulty in timely handling during peak periods, thus affecting the experience and sales, this utility model provides a commercial refrigerated display freezer with automatic defogging function.

[0006] Technical Solution: A commercial freezer display cabinet with automatic defogging function includes a cabinet body, a cabinet door, a display window, a handle, a support plate, a cleaning block, a connecting plate, a motor, a screw, a guide rod, and a controller. The cabinet door is rotatably connected to the front of the cabinet body, and the display window is fixedly connected to the inside of the cabinet door. The handle is fixedly connected to the front of the cabinet door. The motor is installed on the rear of the cabinet door, and a screw is connected to the output shaft of the motor. A connecting plate is threaded onto the screw. A guide rod is fixedly connected to the rear of the cabinet door, and another connecting plate is slidably connected to the guide rod. Both connecting plates have mounting holes. A support plate is installed between the front of the two connecting plates, and a cleaning block is fixedly connected to the front of the support plate. The controller is installed on the front of the cabinet door, and the motor is electrically connected to the controller.

[0007] Furthermore, it also includes a water receiving trough and a water filter plate. The water receiving trough is fixedly connected to the back of the cabinet door, and the water filter plate is fixedly connected inside the water receiving trough.

[0008] Furthermore, it also includes a baffle and a second motor. The baffle is rotatably connected to the top of the water tank, and the second motor is installed on the back of the cabinet door. The second motor is electrically connected to the controller, and the output shaft of the second motor is connected to the baffle.

[0009] Furthermore, it also includes a wastewater box and connecting lugs. A water outlet is provided on the front side of the water tank, and multiple sockets are provided on the front side of the cabinet door. Connecting lugs are inserted into the multiple sockets, and the wastewater box is fixedly connected between the bottoms of the multiple connecting lugs.

[0010] Furthermore, the display windows are made of transparent material.

[0011] Furthermore, the filter plate is tilted from front to back.

[0012] Beneficial effects: 1. The cleaning block is driven by a motor, which completely replaces manual operation, reducing the frequency and workload of manual cleaning. The screw and guide rod work together to make the transmission stable and the force even, avoiding scratches on the display window due to movement deviation, extending the service life of the display window, and solving the problems of the current reliance on manual defogging, which is time-consuming and laborious, and the repeated fogging leads to unstable display effect. It is also difficult to deal with the problem in a timely manner during peak periods, which affects the experience and sales.

[0013] 2. This utility model, by setting up a water receiving tank and a water filter plate, allows water droplets generated during wiping with the cleaning block to be collected and filtered in a directional manner through the water receiving tank and the water filter plate. The water receiving tank covers the area below the display window to ensure that no water droplets are missed. The inclined water filter plate not only filters impurities but also accelerates the water flow to converge at the outlet, preventing water droplets from dripping directly into the freezer and contaminating the goods or accumulating and freezing, thus keeping the freezer clean and reducing subsequent cleaning and maintenance costs.

[0014] 3. This utility model, by setting up a baffle and a second motor, forms a sealed structure by keeping the baffle closed during non-defogging periods, blocking the airflow between the water tank and the outside, effectively reducing the loss of cold energy. The baffle is only opened by the second motor during defogging, reducing the load on the refrigeration system, thereby saving energy consumption and meeting the energy-saving requirements of commercial equipment.

Detailed Implementation

[0025] Example: A commercial freezer display case with automatic defogging function, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the device includes a cabinet body 1, a cabinet door 2, a display window 21, a handle 22, a support plate 3, a cleaning block 31, a connecting plate 32, a motor 34, a screw 35, a guide rod 36, and a controller 6. The cabinet door 2 is rotatably connected to the front of the cabinet body 1. A display window 21, made of transparent material, is welded inside the cabinet door 2. A handle 22 is welded to the left front end of the cabinet door 2. A motor 34 is installed on the rear of the cabinet door 2. A screw 35 is connected to the output shaft of the motor 34, and a connecting plate 32 is threaded onto the screw 35. The rear of the cabinet door 2 is welded with… A guide rod 36 is attached, and another connecting plate 32 is slidably connected to the guide rod 36 via a sliding groove. Each connecting plate 32 has a mounting hole 33. A support plate 3 is installed between the front sides of the two connecting plates 32. A cleaning block 31 is fixed to the front side of the support plate 3. The cleaning block 31 is in contact with the display window 21. The cleaning block 31 is mainly used to clean the display window 21. The cleaning block is made of a low-temperature resistant, soft, and highly absorbent material, such as silicone or high-density sponge. A controller 6 is installed on the front side of the cabinet door 2. The motor 34 is electrically connected to the controller 6.

[0026] like Figure 5 , Figure 6 and Figure 7As shown, it also includes a water receiving trough 4, a filter plate 41, a baffle 43, and a second motor 44. The water receiving trough 4 is welded to the rear side of the cabinet door 2, with its opening facing upwards, covering the width of the display window 21 to ensure no water droplets are missed. The filter plate 41 is welded inside the water receiving trough 4, and it is inclined from front to back. This serves two purposes: firstly, it filters out any small impurities that may be mixed in with the water droplets, preventing blockage of the subsequent drainage structure; secondly, it guides the filtered water towards the outlet 42 of the water receiving trough 4, accelerating drainage efficiency. A baffle 43 is rotatably connected to the top of the water receiving trough 4. A second motor 44 is installed on the rear side of the cabinet door 2, and it is electrically connected to the controller 6. The output shaft of the second motor 44 is connected to the baffle 43. The control technology of the controller 6 is not fundamentally different from existing technologies.

[0027] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a wastewater box 5 and connecting lugs 51. A water outlet 42 is provided on the front side of the water tank 4. Symmetrically distributed insertion holes 23 are provided on both the left and right ends of the front side of the cabinet door 2. Connecting lugs 51 are inserted into each of the two insertion holes 23, and a wastewater box 5 is welded between the bottoms of the two connecting lugs 51. The water outlet 42 of the water tank 4 communicates with the outside of the cabinet door 2 through the connecting groove of the cabinet door 2. When the baffle 43 closes above the water tank 4, the outside of the cabinet door 2 cannot communicate with the inside of the cabinet door 2 through the connecting groove and the water outlet 42.

[0028] During operation, when fog forms on the inside of the display window 21, the controller 6 activates motors 34 and 44. The output shaft of motor 44 rotates, causing baffle 43 to rotate upwards around the water collection tank 4, opening the tank. The output shaft of motor 34 rotates, causing screw 35 to rotate. Screw 35's rotation moves its connecting plate 32 axially, which in turn moves another connecting plate 32 downwards along guide rod 36 via support plate 3. As support plate 3 moves, cleaning block 31 slides synchronously along the inner surface of display window 21, wiping away the condensed fog. The water droplets generated by the cleaning block 31 flow downwards along the surface of the display window 21 under the action of gravity, and finally drip into the water receiving tank 4. The filter plate 41 filters out any tiny impurities that may be mixed in with the water droplets. The filtered water converges towards the outlet 42 of the water receiving tank 4. The wastewater guided by the filter plate 41 is continuously discharged into the wastewater box 5 for temporary storage through the outlet 42 and the connecting groove of the cabinet door 2. After the cleaning block 31 descends to the lowest end and finishes defogging, the output shaft of motor 34 reverses, driving the cleaning block 31 to rise and reset. During the reset process, the cleaning block 31 performs a second wiping of the display window 21.

[0029] After the reset is completed, motor 1 (34) is turned off, motor 2 (44) is controlled to rotate in reverse, drive baffle 43 to reset and close, water tank 4 returns to a sealed state, blocking air circulation between water tank 4 and cabinet 1, reducing cold loss, and repeating the above automatic defogging process. When the water level in wastewater box 5 reaches a certain level, the staff can directly pull out the connecting ear 51, remove wastewater box 5 to empty the wastewater, clean it, and then reinsert the connecting ear 51 to reset it for subsequent collection.
