Description

Technical Field

[0001] The utility model relates to the technical field of anti-fog sliding doors, in particular to an anti-fog sliding door for a refrigerated display cabinet. Background Art

[0002] Refrigerated display cabinets are a type of equipment used to refrigerate and display food, medicine and other items. They are commonly used in shopping malls, supermarkets, convenience stores and other places.

[0003] At present, when the existing refrigerated display cabinets are in use, the sliding door is often covered by fog due to the fog generated inside the refrigerated display cabinet or the large temperature difference between the inside and outside of the refrigerated display cabinet. As a result, people cannot see the items inside the refrigerated display cabinet even if they use a refrigerated display cabinet with a glass sliding door. Therefore, we propose an anti-fog sliding door for a refrigerated display cabinet. Utility Model Content

[0004] The utility model aims to provide a refrigerated display cabinet anti-fog sliding door, which has the advantage of good anti-fog effect and solves the problem that in the existing refrigerated display cabinet, the sliding door is often covered by fog due to fog generated inside the refrigerated display cabinet or a large temperature difference between the inside and outside of the refrigerated display cabinet during use, resulting in people being unable to see the items inside the refrigerated display cabinet even if a refrigerated display cabinet with a glass sliding door is used.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-fog sliding door for a refrigerated display cabinet, comprising a frame, a liquid storage tank is provided on the inner surface of the lower end of the frame, an inner glass is provided at the left end of the inner side of the frame, an inner sealing strip is bonded to the right side of the inner glass, an outer glass is bonded to the right side of the inner sealing strip, an argon gas cavity is provided between the outer glass and the inner glass, an anti-fog layer is bonded to the right side of the outer glass and the left side of the inner glass, the anti-fog layer comprises a PE base film layer and an anti-fog agent coating, an outer sealing strip is provided on one side of the anti-fog layer, both ends of the inner bottom of the frame are fixedly connected with a liquid guide seat, and a liquid guide hole is provided on the inner surface of the liquid guide seat.

[0006] Preferably, the top and the bottom of the frame are both provided with slide grooves, and a drag reduction wheel set is fixedly installed inside the slide groove, and the number of the drag reduction wheel sets is multiple.

[0007] Preferably, the thickness of the PE base film layer is between 150 microns and 500 microns, and the anti-fog agent coating is located on the outside of the PE base film layer.

[0008] Preferably, there are two outer sealing strips, which are respectively located on the right side of the outer glass and on the left side of the inner glass.

[0009] Preferably, the longitudinal section of the liquid-conducting seat is V-shaped, and one side of the liquid-conducting seat and the anti-fog layer are bonded by a sealant.

[0010] Preferably, there are multiple liquid guiding holes, and the liquid guiding holes extend downward to the liquid storage tank.

[0011] Preferably, a drainage groove is provided at the rear end of the right side of the inner cavity of the liquid storage tank, and a rubber block is provided on the inner side of the drainage groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. After the utility model adds argon gas to the cavity between the inner glass and the outer glass, the heat preservation of the sliding door can be improved. The molecules of argon gas are very stable and have a low thermal conductivity, which reduces the temperature difference between the inside and outside of the refrigerated display cabinet, thereby ensuring that the temperature of the outer wall of the cabinet door will not be too low, reducing the probability of fogging. Through the setting of the anti-fog layer, and with the assistance of the PE base film layer and the anti-fog agent coating, the anti-fog agent coating is added to the outside of the PE base film layer. The anti-fog agent is a surfactant with a hydrophilic group, which can be oriented on the plastic surface with the hydrophobic group facing inward and the hydrophilic group facing outward, so that water can easily wet the plastic surface, and the condensed fine water droplets can quickly diffuse to form an extremely thin water layer or large water droplets flowing down the film, thereby avoiding the formation of fogging.

[0014] 2. The utility model is provided with a drainage trough. After the rubber block is taken out from the inner side thereof, the water collected in the liquid storage tank can be discharged into a pre-prepared water tank through the drainage trough, which is convenient for people to use.

[0015] In summary, the utility model ensures the sealing between the inner glass and the outer glass through the cooperation of the outer sealing strip and the inner sealing strip, and reduces the probability of fogging after adding argon gas in the cavity between the inner glass and the outer glass. The anti-fog layer is set and with the assistance of the PE base film layer and the anti-fog agent coating, the formation of fogging is avoided, and the liquid guide seat can receive the water layer or large water droplets flowing down from the anti-fog layer, and the liquid guide hole can introduce the water collected by the liquid guide seat into the liquid storage tank for storage, which is convenient for users to discharge in a centralized manner.
