[0045] At present, the general horizontal freezer is used to store frozen products such as ice cream. In order to ensure that the products do not deteriorate, the temperature inside the box is required to be minus 20 to 30℃. When such products are used in summer, due to the low temperature inside the cabinet and the high temperature and humidity outside the cabinet, the temperature difference between the inside and outside is large, which easily forms condensation on the glass door, affecting the display effect. During peak traffic, customers buy a large amount of goods, frequently open and close the door, and the compressor is often turned on. The temperature inside the box is always very low, and condensation will be serious, affecting the user experience. Especially for products placed outdoors, if there is a price label on the glass door, long-term condensation can easily make the label blurred and the label fall off, causing inconvenience to users, and the condensation on the glass door for a long time cannot be discharged in time. If the glass door is not closed or sealed tightly, the condensation will accumulate to a certain extent and enter the box, causing ice. Therefore, it is necessary to manually wipe the condensation from time to time, affecting the user experience.

[0046] In the related art, a heating wire is arranged corresponding to the glass door to heat the glass door to remove condensation on the glass door. Since the glass door has a large area, the heating wire can only remove the condensation near the heating wire and cannot remove all the condensation on the glass door.

[0047] The present application arranges a hot air duct structure to guide the hot air in the compressor chamber to the outer surface of the upper glass door to prevent condensation on the glass door.

[0048] By arranging air guide structures at the upper and lower ends of the hot air duct structure, the hot air flow direction is adjusted to enhance the effect of preventing condensation.

[0049] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure provides a refrigerator 10, a glass door 11 is arranged at the upper end of the refrigerator 10, and the refrigerator 10 includes a hot air duct structure 12. The hot air duct structure 12 extends upward from the compressor chamber 13 along the inner side wall of the refrigerator 10 to the glass door 11; the hot air duct structure 12 includes a first air duct opening 122 and a second air duct opening 123 that are connected; the first air duct opening 122 corresponds to the air outlet 133 of the compressor 131 arranged in the compressor chamber 13, and the second air duct opening 123 corresponds to the side end of the glass door 11 and extends to the top of the glass door 11, so that the hot air in the compressor chamber 13 can flow along the hot air duct structure 12 to the side end of the glass door 11 and the upper surface of the glass door 11, and the hot air flows in the hot air duct structure 12 in the direction as shown in FIG. Figure 1 The dashed arrow in the middle indicates the direction; wherein, the size of the second air duct opening 123 is equal to the length of the corresponding side end of the glass door 11, so that the hot air in the hot air duct structure 12 can evenly cover the upper surface of the glass door 11 along the side end of the glass door 11 at the same time.

[0050] like Figures 1 to 3As shown, the compressor compartment 13 is arranged at the lower end of the cold cabinet 10, and the glass door 11 is arranged at the upper end of the cold cabinet 10. A hot air duct structure 12 is arranged on the side of the cold cabinet 10 corresponding to the air outlet 133 of the compressor compartment 13, and the first air duct opening 122 of the hot air duct extends downward into the compressor compartment 13, and the first air duct opening 122 is arranged at the front side of the compressor 131 and faces the compressor 131. A fan 132 and a condenser are arranged in sequence behind the compressor 131, and the air outlet 133 of the fan 132 faces the compressor 131 to blow the heat generated by the compressor 131 and the condenser to the air outlet 133 of the compressor compartment 13, and the first air duct opening 122 is arranged at the air outlet 133 of the compressor compartment 13 and faces the compressor 131, so that the hot air flowing to the air outlet 133 of the compressor compartment 13 can continuously enter the hot air duct structure 12 through the first air duct opening 122, and finally flow from the second air duct opening 123 to the glass door 11 at the upper end of the cold cabinet 10. When the refrigerator 10 is in operation, the ambient temperature above the glass door 11 is lower than the ambient temperature in the compressor compartment 13, and there is a thermal pressure difference between the upper and lower air. By utilizing the principle that hot air rises - the so-called chimney effect, the hot air generated by the compressor 131 and the condenser is guided to flow to the upper surface of the glass door 11 through the hot air duct structure 12, and blown out against the glass door 11 to heat the glass door 11 to prevent condensation. If there is too much condensation and the hot air cannot be completely eliminated, the hot air duct structure 12 can also serve as a discharge channel for the condensation to avoid excessive condensation on the glass door 11, without changing the configuration of the original product, without increasing costs, and without increasing energy consumption.

[0051] like Figure 1 and Figure 2 As shown, the size of the second air duct opening 123 in the left-right direction of the refrigerator 10 is equal to the length of the corresponding glass door 11 of the refrigerator 10 in the left-right direction. The hot air in the compressor chamber 13 flows upward from the hot air duct structure 12 and flows out at the second air duct opening 123 to cover the upper surface of the glass door 11, so that the glass door 11 is evenly heated from left to right. As the hot air continues to flow out, the upper surface of the glass door 11 is gradually covered by the hot air from front to back, so as to enhance the effect of preventing condensation on the glass door 11.

[0052] Optionally, the hot air duct structure 12 includes a hot air duct body 121, a first air guide structure 124, and a second air guide structure 125.

[0053] like Figure 3 and Figure 4As shown, the fan 132 blows the hot air in the compressor chamber 13 horizontally forward toward the first air duct opening 122. The first air duct opening 122 is provided with a first air guide structure 124. The first air guide structure 124 guides as much hot air in the compressor chamber 13 as possible into the hot air duct structure 12. The hot air flows upward along the hot air duct structure 12 to the second air duct opening 123. The second air guide structure 125 guides the hot air toward the upper surface of the glass door 11 to cover and flow, so as to heat the upper surface of the glass door 11 and prevent condensation. The flow direction of the hot air under the guidance of the second air guide structure is as shown in FIG. Figure 4 The dashed arrow indicates the direction.

[0054] Optionally, the first air guide structure 124 includes an inclined air duct section 1241, an arc-shaped curved section 1242 and an active port portion 1251. The inclined air duct section 1241 is inclined from top to bottom toward the compressor 131; the first air duct opening 122 is arranged at the lower end of the inclined air duct section 1241, so that the upper end of the first air duct opening 122 is inclined toward the compressor 131; the arc-shaped curved section 1242 connects the hot air duct body 121 and the inclined air duct section 1241; and / or, the second air guide structure 125 includes: an active port portion 1251 is arranged at the upper end of the hot air duct body 121, for changing the direction of the second air duct opening 123 corresponding to the glass door 11, so as to adjust the flow direction of the airflow corresponding to the glass door 11.

[0055] like Figure 3 As shown, the first air duct opening 122 corresponds to the upper front of the compressor 131, the upper end of the inclined air duct section 1241 is connected to the arc-shaped curved section 1242, and the arc-shaped curved section 1242 is transitionally connected to the hot air duct body 121, and the lower end of the inclined air duct section 1241 is tilted downwardly and connected to the first air duct opening 122, so that the hot air enters the inclined air duct section 1241 from the first air duct opening 122 and then flows smoothly upward along the inclined air duct section 1241 into the hot air duct structure 12. The upper end of the movable port portion 1251 is the second air duct opening 123, and the lower end of the movable port portion 1251 is movably connected to the hot air duct body 121, so that the movable port portion 1251 can move relative to the hot air duct body 121 to adjust the direction of the second air duct opening 123 corresponding to the glass door 11, and adjust the direction of the hot air blowing toward the glass door 11.

[0056] Optionally, the movable port portion 1251 includes a first air duct plate 1252 and a second air duct plate 1253. The first air duct plate 1252 is attached to the side wall of the inner container, and the upper end of the first air duct plate 1252 corresponds to the lower wall of the side end of the glass door 11; the second air duct plate 1253 is opposite to the first air duct plate 1252 and is rotatably connected to the hot air duct body 121; wherein the upper end of the second air duct plate 1253 extends upward to above the first air duct plate 1252, so as to adjust the flow direction of the hot air by rotating the second air duct plate 1253.

[0057] like Figure 4As shown, the hot air duct body 121 includes a first air duct plate 1252 adjacent to the side wall of the inner tank and an air duct plate and side plates opposite to the first air duct plate 1252, which are surrounded on all four sides. The first air duct plate 1252 extends upward from the first air duct opening 122 to the lower wall of the glass door 11. The second air duct plate 1253 extends upward from the upper end of the air duct plate of the hot air duct body 121 opposite to the first air duct plate 1252 to above the glass door 11, and can rotate relative to the hot air duct body 121 between a downward state where the upper end of the second air duct plate 1253 is close to the side end of the glass door 11 to press the hot air flow and an open state where the upper end of the second air duct plate 1253 is away from the side end of the glass door 11 to open the second air duct opening 123 to allow the hot air to flow upward. Figure 4 The second air duct plate 1253 rotates in the direction indicated by the arrow II. The connection between the lower end of the second air duct plate 1253 and the hot air duct body 121 is a rotating shaft.

[0058] Optionally, the active port portion 1251 further includes a flexible baffle 1254 . The flexible baffle 1254 is disposed at both side ends of the second air duct plate 1253 , and encloses the main active air duct 1255 of the active port portion 1251 together with the second air duct plate 1253 and the first air duct plate 1252 .

[0059] like Figure 4 As shown, the flexible baffle 1254 is triangular and is used to connect the second air duct plate 1253 and the side plate of the hot air duct body 121 to prevent hot air from leaking from the side of the active port portion 1251. When the second air duct plate 1253 rotates around the rotation axis relative to the hot air duct body 121, the flexible baffle 1254 can be bent or compressed to allow the second air duct plate 1253 to rotate smoothly.

[0060] In some embodiments, the flexible baffle 1254 is a stretch plate or a rubber soft plate or a plate combining a stretch plate and a rubber soft plate.

[0061] Optionally, the refrigerator 10 further includes a cabinet opening structure 14 and a damper 15. The cabinet opening structure 14 is provided at the upper end of the refrigerator 10 for mounting the glass door 11; the damper 15 is provided at the cabinet opening structure 14 corresponding to the second air duct opening 123, and the damper 15 can be switched between a first state of opening to connect the second air duct opening 123 with the glass door 11 and a second state of closing to isolate the second air duct opening 123 from the glass door 11.

[0062] like Figures 4 to 6As shown, the upper cabinet opening of the refrigerator 10 is rectangular, and the outer edge of the cabinet opening structure 14 is adapted to the upper cabinet opening of the refrigerator 10 to form a rectangular frame, which is fixedly buckled on the upper cabinet opening of the refrigerator 10. The cabinet opening structure 14 includes a plurality of steps, which are arranged in sequence from top to bottom, and a glass door 11 is placed on each step, and the plurality of glass doors 11 are staggered in sequence from top to bottom to form a sliding door effect. The damper 15 is arranged on the cabinet opening structure 14, and the outer side of the damper 15 is the second air duct opening 123 of the hot air duct structure 12, and the inner side of the damper 15 is the glass door 11. When the damper 15 is opened, the hot air in the hot air duct structure 12 flows out to the upper surface of the glass door 11, and when the damper 15 is closed, the hot air in the hot air duct structure 12 cannot flow out.

[0063] In some embodiments, the cabinet opening structure 14 opens an air outlet corresponding to the second air duct structure, and the damper 15 is installed at the air outlet of the cabinet opening structure 14 through a rotating shaft, or the damper 15 is sealed at the air outlet through a push-pull structure.

[0064] Optionally, the refrigerator 10 further includes a windshield 16. The windshield 16 is disposed on the lower wall of the side end of the glass door 11 corresponding to the air door 15, and is used to prevent hot air from entering the interior of the refrigerator 10 through the gap between the lower wall of the glass door 11 and the cabinet opening structure 14, thereby affecting the refrigeration effect; wherein the windshield 16 is made of a water-absorbing material, so that condensation water on the inner wall of the glass door 11 passes through the windshield 16 and enters the hot air duct structure 12.

[0065] like Figure 4 and Figure 7 As shown, the wind shield 16 is arranged on the lower wall of the side end of the glass door 11 along the left and right direction of the refrigerator 10. The overall size of the wind shield 16 along the left and right direction of the refrigerator 10 is the same as the size of the second air duct opening 123, so as to prevent the hot air flowing out of the second air duct opening 123 from flowing into the interior of the refrigerator 10 through the gap at the lower end of the glass door 11.

[0066] Optionally, the windshield strip 16 includes an outer frame 161 and a filling cotton 162. The outer frame 161 is made of a rigid material and is used to support the glass door 11; the filling cotton 162 is embedded in the outer frame 161 and is used to block the wind; wherein the filling cotton 162 includes: one or more of sponge, porous cotton and non-woven cotton.

[0067] like Figure 7 and Figure 8 As shown, the outer frame 161 of the windshield strip 16 is made of metal or hard plastic. The windshield strip 16 is fixedly connected to the glass door 11 through the outer frame 161, wherein the connection method includes fastener connection or adhesive connection or a combination of the two. The filling cotton 162 is fixed to the inner wall of the outer frame 161 by adhesive connection, or the outer edge size of the filling cotton 162 is set larger than the inner edge size of the outer frame 161 so that the filling cotton 162 is squeezed by the inner wall of the outer frame 161 to be fixed in the outer frame 161.

[0068] Optionally, the glass door 11 includes a first side end 111 corresponding to the second air duct opening 123 and a second side end 112 opposite to the first side end 111; the first side end 111 is lower than the second side end 112 in the vertical direction, so that condensation water on the glass door 11 can flow along the glass door 11 to the first side end 111 to flow into the hot air duct structure 12.

[0069] like Figure 2 and Figure 3 As shown, the first side end 111 is located at the front end of the refrigerator 10, and the second side end 112 is located at the rear end of the refrigerator 10. The condensation water on the surface of the glass door 11 flows along the glass door 11 to the first side end 111 at the lower position. The first side end 111 corresponds to the second air duct opening 123. The condensation flows into the hot air duct structure 12 from the second air duct opening 123, and then flows downward from the hot air duct structure 12 into the compressor chamber 13 for discharge.
