The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0022] Herein, the terms "first", "second", etc. are only used to distinguish one element from another element, without requiring or implying any actual relationship or order between these elements. In fact, the first element can also be called the second element, and vice versa. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the structure, device or equipment including a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such structure, device or equipment. In the absence of more restrictions, the elements defined by the sentence "comprise one..." do not exclude the existence of other identical elements in the structure, device or equipment including the elements. Each embodiment is described in a progressive manner herein, and each embodiment focuses on the differences from other embodiments, and the same similar parts between the embodiments can be referred to each other.

[0023] The terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. in this document indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this document and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In the description of this document, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a mechanical connection or an electrical connection, it can also be the internal connection of two elements, it can be a direct connection, or it can be indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0024] In some optional embodiments, the refrigeration equipment includes a box body and a door body, and also includes: a door body bracket, which is arranged at the lower part of the door body and connected to the box body; a heat pipe, which is arranged on the door body bracket and connected to the condenser of the refrigeration equipment.

[0025] like Figure 1 and Figure 2 As shown, a heat pipe 31 is arranged in the door body bracket 3 arranged at the lower part of the door body 2 of the refrigeration equipment. The heat pipe 31 is connected to the condenser of the refrigeration equipment, and the refrigerant carrying heat in the condenser can be introduced into the heat pipe 31. The door body bracket 3 is arranged at the lower part of the door body 2. The heat generated by the high-temperature refrigerant in the heat pipe 31 can rise along the door body 2, thereby increasing the temperature of the door body 2 and preventing the door body 2 of the refrigeration equipment from fogging and frosting. The refrigeration equipment provided by the embodiment of the present disclosure can prevent the door body 2 of the refrigeration equipment from fogging and frosting without consuming additional electricity, thereby reducing the power consumption of the refrigeration equipment. The refrigeration equipment here can be a refrigerated display cabinet, a horizontal freezer, an ice bar, a wine cabinet, etc.

[0026] The door support 3 provided with the heat pipe 31 provided in the embodiment of the present disclosure can prevent the door 2 of the refrigeration equipment from fogging. During the operation of the refrigeration equipment, there is a continuously flowing high-temperature refrigerant in the heat pipe 31, which increases the temperature of the door 2 and makes the temperature of the door 2 higher than the dew point, thereby preventing the door 2 from fogging. The frost layer already formed on the door 2 can be melted.

[0027] The door body 2 and the box body 1 constitute a refrigeration chamber of the refrigeration equipment. Optionally, the box body 1 of the refrigeration equipment includes an upper bottom surface, a lower bottom surface and a side surface, wherein the lower bottom surface includes a side facing the user, and the door body bracket 3 is connected to the side of the lower bottom surface facing the user. Optionally, the connection method of the door body bracket 3 and the side of the lower bottom surface facing the user can be adhesive connection, clamping connection, threaded connection, etc. The upper bottom surface, lower bottom surface and side surface here can be understood as a three-dimensional structure with a certain thickness. Optionally, the door body 2 of the refrigeration equipment is a glass door body.

[0028] Optionally, the door body 2 of the refrigeration device is a hollow double-layer glass door body, and the double-layer glass door body includes an inner glass 22 that forms a refrigeration chamber with the box body 1, and an outer glass 21 facing the user. Optionally, the temperature of the heat pipe 31 acts on the outer glass 21 to increase the temperature of the outer glass 21 and prevent the outer glass 21 from fogging and frosting. The hollow glass door body 2 prevents the temperature of the outer glass 21 from being transferred to the inner glass 22, thereby ensuring the temperature of the refrigeration chamber of the refrigeration device.

[0029] “The heat pipe 31 is connected to the condenser of the refrigeration equipment” can be understood as the heat pipe 31 is connected to the refrigerant inlet of the condenser to achieve communication with the condenser; the heat pipe 31 can also be connected to the refrigerant outlet of the condenser to achieve communication with the condenser. The material of the heat pipe 31 can be a metal with good thermal conductivity, such as aluminum, copper or aluminum-copper alloy.

[0030] Optionally, the heat pipe 31 includes a refrigerant inlet and a refrigerant outlet. After the heat pipe 31 is connected to the condenser of the refrigeration equipment, the refrigerant in the heat pipe 31 and the condenser can flow in a manner such that the refrigerant in the refrigerant pipe at the inlet or outlet of the condenser enters the heat pipe 31 through the refrigerant inlet of the heat pipe 31, flows in the heat pipe 31, flows out from the refrigerant outlet of the heat pipe 31, and flows into the refrigerant pipe at the inlet or outlet of the condenser again. Optionally, as Figure 3 As shown, the pipeline at the refrigerant inlet of the heat pipe can pass through the first through hole 3025 to communicate with the condenser, and the pipeline at the refrigerant outlet of the heat pipe can pass through the second through hole 3026 to communicate with the condenser.

[0031] Optionally, the refrigeration equipment further includes: a refrigerant pipe connected to the inlet of the condenser, and the heat pipe is connected to the refrigerant pipe.

[0032] The refrigerant temperature at the refrigerant inlet of the condenser is relatively high, and the heat pipe 31 is connected to the refrigerant pipe at the inlet of the condenser, which increases the temperature of the refrigerant introduced into the heat pipe 31 and improves the anti-fogging and defrosting effects on the door body 2 of the refrigeration equipment.

[0033] The heat pipe 31 includes a refrigerant inlet and a refrigerant outlet. Optionally, a control valve is provided at the refrigerant inlet of the heat pipe 31, and the control valve is used to conduct or block the refrigerant from entering the heat pipe 31. When the refrigeration equipment is in an environment where fogging is easy, such as high temperature and high humidity, the control valve can be opened to introduce the high-temperature refrigerant into the heat pipe 31 to play a role in preventing fogging and defrosting. When the refrigeration equipment is in an environment where fogging is not easy, such as low humidity, the control valve can be closed.

[0034] Optionally, the heat pipe 31 includes a first heat pipe segment, a second heat pipe segment, and a connecting heat pipe segment that bends and connects the first heat pipe segment and the second heat pipe segment, wherein the first heat pipe segment, the second heat pipe segment, and the connecting heat pipe segment can be integrally formed, and the shape of the heat pipe can be U-shaped, such as Figure 2 shown.

[0035] Optionally, the heat pipe is connected in series with the refrigerant pipe.

[0036] The heat pipe 31 and the refrigerant pipe can be connected in series to increase the amount of high-temperature refrigerant entering the heat pipe 31 and improve the defogging and defrosting effect on the door body 2 of the refrigeration equipment. Optionally, the inner diameter of the heat pipe 31 is the same as the inner diameter of the refrigerant pipe to be connected. The heat pipe 31 and the refrigerant pipe can also be connected in parallel to divert the refrigerant in the refrigerant pipe in a feasible manner, and part of the refrigerant flows into the heat pipe 31, which has a defogging and defrosting effect on the door body 2 of the refrigeration equipment. Optionally, the inner diameter of the heat pipe 31 is smaller than the inner diameter of the refrigerant pipe to be connected.

[0037] Optionally, the door body bracket includes: a bottom and a side wall, and the bottom and the side wall constitute a receiving groove.

[0038] The door body bracket 3 is in the shape of a groove. The groove-shaped door body bracket 3 can receive the condensed water formed after the door body 2 is defrosted. When the door body 2 of the refrigeration equipment is defrosted, the solid fog layer or frost layer on the door body 2 melts due to heat and becomes liquid condensed water. If the condensed water flows to the user's floor, water stains will be formed on the floor, and the condensed water stains on the floor need to be cleaned. If the floor is a wooden floor, the water stains that are not cleaned in time will soak the floor and cause damage to the floor. The groove-shaped door body bracket 3 can accommodate the condensed water flowing down from the door body 2, preventing the condensed water from flowing to the user's floor to form water stains, avoiding the user from cleaning the water stains, and protecting the user's floor from being soaked. A heat pipe 31 with a relatively high temperature is arranged in the door body bracket 3, and the condensed water flowing into the groove evaporates due to heat, avoiding people from cleaning the condensed water in the groove.

[0039] Optionally, the heat pipe is laid on the bottom or side wall of the door support.

[0040] The heat pipe 31 disposed in the door support 3 can be laid on the bottom 301 of the door support 3. Optionally, the heat pipe 31 can be fixed to the bottom 301 of the door support 3 by one or more clamps. The heat pipe 31 is laid on the bottom 301 of the door support 3, so as to better utilize the space of the door support 3, reduce the width of the door support 3, and improve the overall aesthetics of the refrigeration equipment. Figure 1 and Figure 2 The heat pipe 31 in the door support 3 shown is discontinuous, and the blank part of the heat pipe is blocked by the clamp. Optionally, the heat pipe 31 can be laid on the side wall 302 of the door support 3, and the heat pipe 31 can be fixed to the side wall 302 of the door support 3 by one or more clamps. The heat pipe 31 is arranged on the side wall 302 of the door support 3, which is conducive to the hot air generated by the heat pipe 31 to rise along the door body 2, thereby improving the defogger and defrost effect on the door body 2. The side wall 302 of the door support 3 includes an inner side wall 3021 connected to the box body 1, and an outer side wall 3022 opposite to the inner side wall 3021. Optionally, part of the heat pipe 31 is arranged on the outer wall 3022 of the door body bracket 3, and part of the heat pipe 31 is arranged on the bottom 301 of the door body bracket 3, so that the heat generated by the heat pipe 31 can rise along the outer glass 21 of the door body 2, and the outer glass 21 of the door body 2 is defogged and defrosted in a targeted manner, so that the temperature of the inner glass 22 of the door body 2 is not affected, thereby ensuring the temperature of the refrigeration equipment.

[0041] Optionally, the bottom of the door support 3 is a horizontal plane or an inclined plane.

[0042] The side wall 302 of the door support 3 includes an inner wall 3021 connected to the box body 1, an outer wall 3022 opposite to the inner wall 3021, and a first connecting side wall 3023 and a second connecting side wall 3024 connecting the inner wall 3021 and the outer wall 3022, wherein the first connecting side wall 3023 is close to the door body rotation axis, and the second connecting side wall 3024 is opposite to the first connecting side wall 3023. The distance between the first connecting side wall 3023 and the second connecting side wall 3024 is defined as the length of the door support 3. When the bottom 301 of the door support 3 is a horizontal plane, the condensed water flowing into the door support 3 can be evenly spread and distributed on the horizontal bottom surface, thereby increasing the evaporation rate of the condensed water in the door support 3. At the same time, the length of the heat pipe 31 in the door support 3 can also be increased to improve the defogger and defrost effect of the heat pipe 31. Optionally, the length of the heat pipe 31 is 2-4 times the length of the door support 3.

[0043] When the bottom 301 of the door support 3 is an inclined surface, it can be inclined from the second connecting side wall 3024 to the first connecting side wall 3023, or from the first connecting side wall 3023 to the second connecting side wall 3024. Among them, taking the bottom 301 of the door support 3 as an example of inclination from the second connecting side wall 3024 to the first connecting side wall 3023, the length of the first heat pipe section and the second heat pipe section is 1 / 3-2 / 3 of the length of the door support 3. Optionally, the inner wall 3021 is provided with a first through hole 3025 and a second through hole 3026 through which the heat pipe 31 can pass, and the first through hole 3025 and the second through hole 3026 are both concentrated on the side of the inner wall 3021 close to the door body rotation axis, so that the heat pipe 31 is distributed at a lower position of the inclined surface. The condensed water flowing into the door support 3 can converge along the inclined surface in the inclined bottom surface, and the heat pipe 31 can concentrate the condensed water that converges to the lower position of the inclined surface and evaporate it.

[0044] Optionally, the outer diameter of the heat pipe is smaller than the depth of the door support.

[0045] The outer diameter of the heat pipe 31 is smaller than the depth of the door support 3. When the door 2 of the refrigeration equipment is in a closed state, part of the heat pipe 31 will not be exposed outside the door support 3, thereby improving the overall aesthetics of the refrigeration equipment.

[0046] Optionally, the side wall of the door support includes an inner wall 3021 connected to the box body, and the inner wall 3021 is provided with a first through hole 3025 and a second through hole 3026 through which the heat pipe can pass.

[0047] like Figure 3As shown, the inner side wall 3021 of the door support 3 is provided with a first through hole 3025 and a second through hole 3026, which is conducive to the connection between the heat pipe 31 and the condenser of the refrigeration equipment. Optionally, the first through hole 3025 and the second through hole 3026 are arranged adjacent to each other, for example, the distance between the first through hole 3025 and the second through hole 3026 can be 1-5cm. Optionally, the first through hole 3025 and the second through hole 3026 can be arranged on the side of the inner side wall 3021 close to the first connecting side wall 3023, or on the side of the inner side wall 3021 close to the second connecting side wall 3024, or in the middle position of the inner side wall 3021. Optionally, the first through hole 3025 and the second through hole 3026 can be arranged according to the position of the refrigerant pipe at the inlet of the condenser in the refrigeration equipment.

[0048] Optionally, the lower bottom surface of the door body is provided with an arc angle.

[0049] When the door body 2 of the refrigeration equipment is heated for defrosting, the thin water film on the surface of the door body 2 will gradually gather along the door body 2 to the lower bottom surface of the door body 2 due to its own gravity. The setting of the arc angle 211 of the lower bottom surface of the door body 2 will guide the condensed water in the downward flow process, forming water droplets on the lower side of the arc angle 211 of the door body 2. When the water droplets grow to a certain size, they drip into the grooved door body bracket 3 due to gravity, as shown in FIG. Figure 4 , Figure 5 and Figure 6 Optionally, the arc angle 211 is arranged on the outer glass 21 side of the door body 2 .

[0050] Optionally, the larger the radius of the arc angle, the smaller the width of the door body support.

[0051] The distance between the inner wall 3021 and the outer wall 3022 of the door support 3 is defined as the width of the door support 3. The larger the radius of the arc angle 211, the smaller the width of the door support 3, so that the water droplets formed by condensed water can smoothly fall into the groove-shaped door support 3. It can be understood that the radius of the arc angle is the radius of the virtual circle after the arc angle is supplemented into a virtual circle. Figure 4 and Figure 5 As shown, Figure 4 The radius of the arc angle 211 of the door body 2 is larger than Figure 5 The radius of the arc angle 211 of the door body 2 is shown.

[0052] The disclosed embodiment also provides a refrigeration device with a hydrophilic coating on the door body.

[0053] The refrigeration equipment includes a box body and a door body, and also includes: a door body bracket, which is arranged at the lower part of the door body and connected to the box body; a heat pipe, which is arranged on the door body bracket and connected to the condenser of the refrigeration equipment, and the surface of the door body is coated with a hydrophilic coating.

[0054] The hydrophilic coating applied on the surface of the door body 2 can make the moisture in the air form a thin water film on the surface of the door body 2 to prevent the surface of the door body 2 from fogging. Due to its own gravity, the thin water film on the surface of the door body 2 will gradually gather along the door body 2 to the lower side of the door body 2 to form condensed water, which will flow to the door body bracket 3 to prevent the condensed water from flowing to the user's floor and forming water stains on the floor.

[0055] Optionally, the outer surface of the door body is coated with a first hydrophilic coating.

[0056] The outer surface of the door body 2 can be understood as the side of the door body 2 facing the user. When the door body 2 is a vacuum double-layer glass, the outer surface of the door body 2 can be the outer surface of the outer glass 21. The first hydrophilic coating can make the moisture in the air form a thin water film on the outer surface of the outer glass 21 without affecting the permeability of the outer glass 21.

[0057] Optionally, the first hydrophilic coating is a chemical coating containing nano-silicon dioxide and super-hydrophilic functional groups, which can form a chemical bond with the outer glass 21 matrix of the door body 2, thereby forming a first hydrophilic coating, which is resistant to wiping and has a long service life of about 20 years. The contact angle of the first hydrophilic coating is less than 5°, for example, the contact angle can be 4.3°.

[0058] Optionally, the thickness of the first hydrophilic coating is 10-30 nm.

[0059] The thickness of the first hydrophilic coating layer can be 10nm, 12nm, 13nm, 15nm, 17nm, 19nm, 20nm, 22nm, 24nm, 26nm, 28nm, 30nm, which does not affect the light transmittance of the glass door body 2. Optionally, the thickness of the first hydrophilic coating layer gradually increases from the middle to the edge of the outer glass 21, guiding the formation of a thin water film at the edge of the outer glass 21, thereby improving the light transmittance of the middle part of the outer glass 21.

[0060] Optionally, the first hydrophilic coating is applied to an edge portion of the outer surface of the door body.

[0061] The first hydrophilic coating is applied to the edge of the outer glass 21, guiding the thin water film to form at the edge of the outer glass 21, thereby improving the light transmittance of the middle part of the outer glass 21. The edge of the outer glass 21 includes an upper edge, a lower edge, and two side edges. Optionally, the first hydrophilic coating is applied to the two side edges of the outer glass 21, and the condensed water formed by the thin water film can be guided to flow to the door body bracket 3. Optionally, the coating width of the first hydrophilic coating on the side edge is 15-25 cm.

[0062] Optionally, the first hydrophilic coating is in a first grid shape.

[0063] “The first hydrophilic coating is in a first grid shape” can be understood as coating the first hydrophilic coating on the outer surface of the door body 2 along a preset path, and after coating, a first grid shape is obtained, such as Figure 7 As shown. It is understandable that the first grid shape is transparent. The first hydrophilic coating 212 in the first grid shape can guide the thin water film to form on a preset path, and can specifically avoid the area of ​​the door body 2 used to display the items in the refrigeration device, thereby improving the light transmittance of the items in the refrigeration device. Optionally, the coating width of the first hydrophilic coating 212 in the first grid shape is 10-20 cm.

[0064] Optionally, the inner surface of the door body is coated with a second hydrophilic coating.

[0065] The inner surface of the door body 2 is coated with a second hydrophilic coating, which can make the moisture in the air form a thin water film on the inner surface to prevent the inner surface of the door body 2 from fogging. The inner surface of the door body 2 can be understood as the side of the door body 2 used to form the refrigeration chamber. When the door body 2 is a vacuum double-layer glass, the inner surface of the door body 2 can be the side of the inner glass 22 facing the refrigeration chamber, and can also be called the outer surface of the inner glass 22. The second hydrophilic coating can make the moisture in the air form a thin water film on the outer surface of the inner glass 22 without affecting the permeability of the inner glass 22.

[0066] Optionally, the second hydrophilic coating is a chemical coating whose components include nano-silicon dioxide and super-hydrophilic functional groups, which can form a chemical bond with the inner glass 22 matrix of the door body 2, thereby forming a second hydrophilic coating, which is resistant to wiping and has a long service life of about 20 years. The contact angle of the second hydrophilic coating is less than 5°, for example, the contact angle can be 4.3°.

[0067] Optionally, the thickness of the second hydrophilic coating is 10-50 nm.

[0068] The thickness of the second hydrophilic coating can be 10nm, 15nm, 20nm, 25nm, 30nm, 35nm, 40nm, 45nm, 50nm, which does not affect the light transmittance of the glass door body 2. Optionally, the thickness of the second hydrophilic coating gradually increases from the middle to the edge of the inner glass 22, guiding the thin water film to form at the edge of the inner glass 22, thereby improving the light transmittance of the middle part of the inner glass 22. When the temperature of the items placed in the refrigeration equipment is high, the high-temperature items are likely to cause frost on the outer surface of the inner glass 22, and the thickness of the second hydrophilic coating can be 20-50nm, which improves the hydrophilic performance of the water in the refrigeration cavity.

[0069] Optionally, the second hydrophilic coating is in a second grid shape.

[0070] Similarly, "the second hydrophilic coating is a second grid-like shape" can be understood as coating the second hydrophilic coating on the outer surface of the inner glass 22 of the door body 2 along a preset path. After coating, a second grid-like shape is obtained, which can guide the thin water film to form on the preset path, and can specifically avoid the area of ​​the door body 2 used to display the items in the refrigeration equipment, thereby improving the light transmittance of the items in the refrigeration equipment. Optionally, the coating width of the second hydrophilic coating in the second grid shape is 10-20cm. Optionally, the first grid shape and the second grid shape are arranged relative to each other to improve the light transmittance of the items in the refrigeration cavity.

[0071] Optionally, a water absorbing element is provided at the lower portion of the inner surface of the door body.

[0072] The water absorbing element disposed on the inner surface of the door body 2 can absorb the condensed water flowing down from the inner surface of the door body 2. Optionally, the water absorbing element can be a fabric with a certain thickness and water absorbing properties, such as a fiber fabric. The water absorbing element can be connected to the inner glass 22 of the door body 2 in a detachable manner such as snap connection or magnetic attraction. When the amount of condensed water absorbed in the water absorbing element is large, the water absorbing element can be taken out and the condensed water in the water absorbing element can be discharged by dehydration or other means, so that the water absorbing element can be reused.
