Description
Technical Field
[0001] The utility model relates to the technical field of vertical refrigerators, in particular to an automatic condensation water discharge device for a glass door. Background Art
[0002] Vertical freezers on the market usually include a cabinet body and a glass door. The refrigeration system is installed in the machine room of the cabinet body. During the use of the vertical freezer, due to the large temperature difference between the inside and outside of the cabinet body, when the saturated steam outside the cabinet body reaches its dew point, it will condense into dew drops on the outer surface of the glass door, thereby affecting the transparency of the glass door and reducing the display effect inside the cabinet body.
[0003] In response to the problem of condensation on glass doors, most refrigerators currently use the following two solutions: The first is to coat the inner side of the outer glass with a layer of LOW-E film to reduce the condensation on the outer surface of the glass door by reducing the heat transfer between the inside and outside of the cabinet. This is commonly known as LOW-E glass in the industry. However, the disadvantage is that the effect is limited. When the humidity of the outside air is high, exceeding 40%RH, the effect is not obvious, and there will still be condensation. In addition, the LOW-E film will also affect the transmittance of light, because the LOW-E film is a low-radiation material and metal oxide touch, and has a base color, and the display effect will be worse than that of ordinary glass;
[0004] The second method is to coat a layer of conductive film on the inner side of the outer glass. If the glass door is surrounded by aluminum alloy profiles, electric heating wires must be added to the aluminum alloy profiles. By applying voltage, the conductive film and the electric heating wires will emit heat to evaporate the condensation water attached to the outer surface of the glass door. This is commonly known as the electric heated glass door in the industry. The disadvantages are: the cost is relatively high, the conductive film and the electric heating wire both consume electricity, the energy consumption increases, and there are safety hazards.
[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention
[0006] The purpose of the utility model is to provide an automatic condensation water discharge device for a glass door in view of the deficiencies in the prior art. The utility model can not only ensure that condensation water on the outer surface of the glass door will not adhere to the glass door, but also save costs, reduce energy consumption, have good safety, and ensure the display effect of the upright refrigerator.
[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an automatic condensation water discharge device for a glass door, comprising a hydrophobic film and a decorative cover shell, the hydrophobic film is made of a transparent material, the hydrophobic film is fully covered and plated on the outer surface of the glass door, the upper side and the rear side of the decorative cover shell are open, the decorative cover shell is fixedly installed on the front lower part of the cabinet and is located directly below the glass door, the inner upper part of the decorative cover shell is fixedly connected with a water receiving trough covering the upper port of the decorative cover shell, the bottom of the water receiving trough is connected with a drain pipe, the inner bottom of the decorative cover shell is provided with a water receiving box with a top opening, the lower end of the drain pipe is provided directly above the water receiving box, the width of the decorative cover shell is the same as the width of the cabinet, and the width of the water receiving trough is greater than or equal to the width of the glass door.
[0008] Based on the above, the bottom plate of the water receiving trough is a V-shaped folded plate with high sides and a bottom in the middle. The front side of the bottom plate of the water receiving trough is fixedly connected to the inner side of the front side plate of the decorative cover shell, and the rear side, left side and right side of the bottom plate of the water receiving trough are integrally connected with an upwardly bent water retaining folded edge. The upper edge of the left water retaining folded edge is integrally formed and fixedly connected to the left edge of the upper port of the decorative cover shell, and the upper edge of the right water retaining folded edge is integrally formed and fixedly connected to the right edge of the upper port of the decorative cover shell. A drain outlet is provided in the center of the bottom plate of the water receiving trough, and a drainage floor drain is installed in the drain outlet. The drain pipe is vertically arranged below the water receiving trough, and the upper end of the drain pipe is fixedly connected to the lower end of the drainage floor drain.
[0009] Based on the above, the bottom plate of the water trough includes a left inclined plate, a middle flat plate and a right inclined plate. The left inclined plate is inclined with the left side higher than the right side, and the right inclined plate is inclined with the left side lower than the right side. The right side edge of the left inclined plate and the left side edge of the middle flat plate, as well as the right side edge of the middle flat plate and the left side edge of the right inclined plate are all integrally formed and fixedly connected, and the drain outlet is set in the center of the middle flat plate.
[0010] Based on the above, the upper end of the drainage pipe is threadedly connected to the lower end of the drainage floor drain.
[0011] Based on the above, electric heating wires are evenly arranged on the inner bottom of the water receiving box, and both ends of the electric heating wires extend upward through the upper part of one side plate of the water receiving box and extend out of the water receiving box to be connected to the power supply of the vertical refrigerator. A liquid level sensor is also arranged on the lower side of the inner wall of one side plate of the water receiving box. The liquid level sensor is higher than the electric heating wires arranged on the bottom of the water receiving box. The control system of the vertical refrigerator is respectively connected to the power switch of the electric heating wire and the liquid level sensor control.
[0012] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model covers the outer surface of the glass door with a transparent hydrophobic film, which has almost no effect on the light transmittance of the glass door.

The bottom of the water receiving trough is connected with a drain pipe. A water receiving box located below the drain pipe is arranged at the inner bottom of the decorative cover. The width of the water receiving trough is greater than or equal to the width of the glass door. In this way, when condensation water is formed on the outer surface of the glass door, the condensation water will quickly flow along the outer surface of the glass door due to the presence of the hydrophobic film. The condensed water flows down and falls into the water receiving trough, ensuring that the condensed water leaves the glass door in time, and the display effect of the upright freezer is well guaranteed. There is no need to manually wipe the condensed water on the outer surface of the glass door. The condensed water is then discharged into the water receiving box through the drain pipe to evaporate naturally. When the liquid level of the condensed water in the water receiving box rises to the liquid level sensor, the liquid level sensor detects the liquid level and transmits the signal to the control system of the upright freezer. The control system of the upright freezer controls the electric heating wire to be energized and work, and the electric heating wire is heated to accelerate the evaporation of the condensed water. Compared with the prior art, the utility model can not only ensure that the condensed water on the outer surface of the glass door will not adhere to the glass door, but also save costs, reduce energy consumption, have good safety, and can ensure the display effect of the upright freezer.

[0018] The technical solution of the utility model is further described in detail below through specific implementation methods.
[0019] Example 1
[0020] like Figure 1-4As shown, an automatic condensation water discharge device for a glass door includes a hydrophobic film and a decorative cover shell 1, wherein the hydrophobic film is made of a transparent material and is fully coated on the outer surface of a glass door 2. The upper side and the rear side of the decorative cover shell 1 are open, and the decorative cover shell 1 is fixedly mounted on the front lower part of a cabinet body 3 and is located directly below the glass door 2. A water receiving trough 4 covering the upper port of the decorative cover shell 1 is fixedly connected to the inner upper part of the decorative cover shell 1, and a drain pipe 5 is connected to the bottom of the water receiving trough 4. A water receiving box 6 with an open top is provided at the inner bottom of the decorative cover shell 1, and the lower end of the drain pipe 5 is provided directly above the water receiving box 6. The width of the decorative cover shell 1 is the same as the width of the cabinet body 3, and the width of the water receiving trough 4 is greater than or equal to the width of the glass door 2. When the external saturated steam reaches the dew point, condensation water 10 will adhere to the outer surface of the glass door 2. Since the outer surface of the glass door 2 is coated with a hydrophobic film, the condensation water 10 will flow downward along the outer surface of the glass door 2 and fall into the water receiving groove 4, and then be discharged into the water receiving box 6 through the drain pipe 5. The water in the water receiving box 6 evaporates naturally. Moreover, the hydrophobic film is made of transparent material and has almost no effect on the light transmittance of the glass door 2, which well guarantees the display effect of the vertical refrigerator. Compared with the conductive film, the hydrophobic film has low cost, does not consume electricity, is energy-saving, and has good safety.
[0021] The bottom plate of the water receiving trough 4 is a V-shaped folded plate with high sides and a bottom in the middle. The front side of the bottom plate of the water receiving trough 4 is fixedly connected to the inner side of the front side plate of the decorative cover shell 1. The rear side, left side and right side of the bottom plate of the water receiving trough 4 are integrally formed with an upwardly bent water retaining folded edge 7. The upper edge of the left water retaining folded edge 7 is integrally formed and fixedly connected to the left edge of the upper port of the decorative cover shell 1, and the upper edge of the right water retaining folded edge 7 is integrally formed and fixedly connected to the right edge of the upper port of the decorative cover shell 1. A drainage outlet is provided in the center of the bottom plate of the water receiving trough 4, and a drainage floor drain 8 is installed in the drainage outlet. The drainage pipe 5 is vertically arranged below the water receiving trough 4, and the upper end of the drainage pipe 5 is fixedly connected to the lower end of the drainage floor drain 8. In this way, the middle part of the inner bottom of the water receiving trough 4 is at the lowest position, and the condensation water 10 flows downward from the glass door 2 and directly falls into the water receiving trough 4, and then gathers in the middle part of the inner bottom of the water receiving trough 4, and then enters the drain pipe 5 through the drainage floor drain 8, and the condensation water 10 is then discharged into the water receiving box 6 through the drain pipe 5.
[0022] The bottom plate of the water receiving trough 4 includes a left inclined plate, a middle flat plate and a right inclined plate. The left inclined plate is inclined with the left side higher than the right side, and the right inclined plate is inclined with the left side lower than the right side. The right side edge of the left inclined plate and the left side edge of the middle flat plate, as well as the right side edge of the middle flat plate and the left side edge of the right inclined plate are integrally formed and fixedly connected, and the drain outlet is arranged at the center of the middle flat plate.
[0023] The upper end of the drainage pipe 5 is threadedly connected to the lower end of the drainage floor drain 8 .
[0024] In this embodiment, the decorative cover 1 and the water tank 4 are made of integral injection-molded ABS material. In other embodiments, the decorative cover 1 and the water tank 4 are welded by sheet metal parts. The decorative cover 1 and the water tank 4 are easy to manufacture and have low cost.
[0025] Example 2
[0026] On the basis of Example 1, electric heating wires 9 are evenly arranged at the inner bottom of the water receiving box 6. The two ends of the electric heating wires 9 extend upward through the upper part of a side plate of the water receiving box 6 and extend out of the water receiving box 6 to connect with the power supply of the vertical refrigerator. A liquid level sensor (not shown) is also arranged at the lower side of the inner wall of a side plate of the water receiving box 6. The liquid level sensor is higher than the electric heating wire 9 arranged at the bottom of the water receiving box 6. The control system of the vertical refrigerator is respectively connected to the power switch and the liquid level sensor of the electric heating wire 9. When the condensation water 10 is discharged into the water receiving box 6 through the drain pipe 5 and the liquid level rises to the liquid level sensor, the liquid level sensor detects the liquid level and transmits the signal to the control system of the vertical refrigerator. The control system of the vertical refrigerator controls the electric heating wire 9 to be powered on, and the electric heating wire 9 is heated to accelerate the evaporation of the condensation water 10.
[0027] The hydrophobic film, the electric heating wire 9 and the liquid level sensor are all of conventional design and can be purchased on the market. The specific structure and working principle will not be described in detail. The power supply and control system of the upright freezer are also conventional technologies. In this embodiment, the control system of the upright freezer is respectively connected to the power switch of the electric heating wire 9 and the liquid level sensor control, which is also conventional control technology and does not involve new computer programs.
