A PLC controller 2 is fixedly installed on one side of the cabinet 1 (located in front of the adjacent block 8). The inner cavity of the door frame 3 is provided with grooves on opposite sides. The inner cavity of the grooves is provided with fixed slots near the top and bottom. The inner cavity of the fixed slots is provided with buffer components 7. The inner cavity of the grooves is provided with rectangular slots on opposite sides. The inner cavity of the door frame 3 is provided with water absorption components 6 near the bottom. The opposite side of the door frame 3 is fixedly installed with protective pads 9. The protective pads 9 are movably inserted into the inner cavities of the adjacent grooves. The buffer assembly 7 includes a compression block 74 fixedly installed on one side of the protective pad 9 near the top. A movable block 71 is provided on one side of the compression block 74. A damper 72 is fixedly installed on one side of the movable block 71 near the top and bottom. The inner cavity of the damper 72 is fixedly connected to the inner cavity sidewall of the fixed groove. A damping spring 73 is movably sleeved on the outer periphery of the damper 72. The two ends of the damping spring 73 are fixedly connected to the fixed groove and the movable block 71, respectively. A sound generator 75 is fixedly installed on the front side of the door frame 3 near one side (the sound generator 75 can emit sound and is electrically connected to the PLC controller).

[0019] Specifically, when the user closes the door, with the cooperation of the buffer assembly 7, the user can squeeze the movable block 71 by the squeezing block 74 after the door is closed, and the movable block 71 can be moved to one side. The squeezing damper 72 and the damping spring 73 can buffer when the door is closed, reduce the generation of noise, and improve the effect of the device.

[0020] A distance sensor 711 is fixedly installed on one side of the movable block 71, and the distance sensor 711 is electrically connected to the PLC controller 2.

[0021] Specifically, after the door is closed, if the distance between the distance sensor 711 and the inner wall of the fixed groove increases, the distance sensor 711 will transmit a signal to the PLC controller 2 and emit a sound through the sound generator 75, which can remind the user that the glass door body 4 is not completely closed, thus preventing cold air from escaping and saving energy.

[0022] Magnetic blocks A31 are fixedly installed on opposite sides of the two door frames 3, and magnetic blocks B32 are fixedly installed in the inner cavity of the rectangular grooves. Magnetic blocks A31 are magnetically attracted to adjacent magnetic blocks B32 respectively.

[0023] Specifically, by setting magnetic blocks A31 and B32, the glass door body 4 can be closed stably and will not be easily opened.

[0024] On the opposite side of the stop block 8, scraper strips 81 are fixedly installed. Two rectangular openings are opened at the bottom of the inner cavity of the door frame 3 near the middle position, and protective nets 82 are fixedly installed in the inner cavity of the rectangular openings.

[0025] Specifically, by setting up a scraper 81, water mist 1 on the glass door body 4 can be cleaned, and the cleaned water mist enters the inner cavity of the door frame 3 through the protective net 82.

[0026] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 2 and Figure 7 The water-absorbing component 6 includes a pressure sensor 61 fixedly installed in the inner cavity of the door frame 3, an audible and visual alarm 62 fixedly installed on the front side of the door frame 3 near the top, and a water-absorbing expansion pad 63 provided at the bottom of the inner cavity of the door frame 3. The inner cavity of the water-absorbing expansion pad 63 is filled with highly absorbent resin material.

[0027] Specifically, when wiping water off the glass on the glass door body 4, the water absorption component 6 is used in conjunction with the water absorption expansion pad 63 to absorb water and expand. When it expands to a certain limit, it can squeeze the pressure sensor 61. The pressure sensor 61 activates the audible and visual alarm 62 through the PLC controller 2, reminding the staff to replace the pressure sensor 61 in time, which is conducive to the absorption and treatment of the wiped-off water.

[0028] The bottom of the water-absorbing expansion pad 63 is fixedly installed with a hook and loop 631, and the bottom of the hook and loop 631 is provided with a hook and loop 632. The bottom of the hook and loop 632 is fixedly connected to the bottom of the inner cavity of the door frame 3.

[0029] Specifically, by setting the hook and loop fastener 632 and the hook and loop barbed fastener 631, it is convenient to replace the water-absorbing expansion pad 63, which is conducive to the absorption and treatment of the scraped water.

[0030] It should be noted that all electrical components in the device are connected to an external power source. The pressure sensor 61, the audible and visual alarm 62, the distance sensor 711, and the sound generator 75 are all existing technologies, and their working principles will not be elaborated here.

[0031] Working Principle: When this utility model is in use, when the glass door body 4 is opened, the scraper 81 can scrape off the water on the glass of the glass door body 4. The water falls from the protective net 82 into the inner cavity of the glass door body 4 and can be absorbed by the water-absorbing expansion pad 63. As the water-absorbing expansion pad 63 expands continuously, it can compress the pressure sensor 61. The PLC controller 2 activates the audible and visual alarm 62 to remind the staff to replace the pressure sensor 61 in time. This facilitates the absorption and treatment of the scraped water. On the upper door frame 3, after the door is closed, the pressing block 74 can press the movable block 71 and move the movable block 71 to one side. The pressing damper 72 and the damping spring 73 can buffer when the door is closed, reduce noise generation, and improve the effect of the device. In addition, by setting the distance sensor 711, the distance between the distance sensor 711 and the inner cavity side wall of the fixed groove can be measured. When the distance is large, the sounder 75 can be activated by the PLC controller 2 to warn the staff that the door is not closed tightly, causing cold air to escape and increasing the cost of using the cabinet 1.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
