Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and in particular to an anti-condensation refrigerator. Background Technology

[0002] The temperature inside the refrigerator's cooling compartment is significantly lower than the ambient temperature, causing cold air to leak out and lowering the surface temperature of the refrigerator body in contact with the outside environment. This makes condensation more likely to occur, especially around the door seal where the door connects to the refrigerator body, where poor insulation and sealing can easily lead to condensation. To prevent condensation around the refrigerator door seal, current technologies typically use anti-condensation pipes to increase the temperature around the door seal, thereby preventing condensation.

[0003] However, in existing technologies, the anti-condensation pipe is part of the compressor, and its temperature is strongly correlated with the compressor's operation. When the compressor is running, the temperature of the anti-condensation pipe rises, which helps prevent condensation; when the compressor stops running, the temperature of the anti-condensation pipe drops, and its anti-condensation effect is poor.

[0004] Meanwhile, the anti-condensation pipes in existing technologies are generally made of rigid iron or copper pipes. The anti-condensation pipes are set between the door and the refrigerator body, which are prone to deformation and difficult to install properly. It is easy for the anti-condensation pipes to not fit properly with the refrigerator body, which affects the heat transfer of the anti-condensation pipes to the door seal and thus affects the anti-condensation effect.

[0005] In addition to raising the temperature around the door seal, the heat from the anti-condensation pipe also allows some heat to seep into the refrigerator's cooling compartment, affecting energy consumption. Furthermore, the anti-condensation pipe carries refrigerant, is relatively long, requires welding, and is thus relatively complex to assemble. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing anti-condensation pipe assembly being complex and the anti-condensation effect being poor when the compressor is not running, and to provide an anti-condensation refrigerator.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] An anti-condensation refrigerator includes a refrigerator body, a door, and a compressor. The refrigerator body has a refrigeration compartment. The door has an airflow channel, which includes an air inlet. An air suction device is installed at the air inlet. The air suction device can operate independently of the compressor and is used to send air from outside the refrigerator into the airflow channel. The airflow channel has a vent hole penetrating the wall of the airflow channel. The vent hole has an air outlet facing the side frame of the refrigerator body. When the door is closed, the vent hole is not connected to the refrigeration compartment.

[0009] In this technical solution, an airflow channel is set on the door, along with a suction device that operates independently of the compressor. The suction device draws outside air into the airflow channel, allowing it to flow through the vents to the side frame of the refrigerator. Since the outside air is warmer than the cooling compartment, it exchanges heat with the side frame, removing cold air and raising its temperature. This prevents condensation from forming on the side frame due to the large temperature difference between the side frame and the room temperature. Because the suction device operates independently of the compressor, it remains operational even when the compressor stops, ensuring consistent anti-condensation performance. Furthermore, when the door is closed, the vents are not connected to the cooling compartment, preventing relatively warm air from entering the cooling compartment.

[0010] Preferably, the airflow channel includes a first portion near the air inlet and a second portion away from the air inlet, and at least part of the cross-sectional area of ​​the first portion gradually decreases along the airflow direction of the airflow channel.

[0011] In this technical solution, by setting the first part to have a cross-sectional area that gradually decreases along the air supply direction, the air pressure at the end near the air inlet is greater than the air pressure at the end far from the air inlet, which is more conducive to air supply.

[0012] Preferably, the airflow channel includes a first portion near the air inlet and a second portion away from the air inlet, and the cross-sectional area of ​​the second portion remains unchanged along the airflow direction of the airflow channel.

[0013] In this technical solution, compared to setting the second part as a channel with a changing cross-sectional area, setting the cross-sectional area of ​​the second part to remain constant can reduce the resistance to airflow within the second part.

[0014] Preferably, the air inlet is located at the end near the first part and away from the second part, the air suction device is a radial fan, the end of the first part away from the second part has an arc-shaped portion, the radial fan is located inside the arc-shaped portion, the arc-shaped portion is coaxially arranged with the radial fan, and the inner diameter of the arc-shaped portion is larger than the outer diameter of the radial fan.

[0015] In this technical solution, by setting a radial fan in the air intake device and setting an arc-shaped part that matches the shape of the radial fan, the flow resistance after the radial fan draws air into the airflow channel is reduced.

[0016] Preferably, one of the sidewalls of the remaining portion of the first part is smoothly connected to one of the ends of the arcuate portion.

[0017] In this technical solution, by setting one of the sidewalls of the remaining part of the first part to be smoothly connected to one of the ends of the arc-shaped part, the resistance when air flows out of the arc-shaped part can be reduced.

[0018] Preferably, the airflow channel is arranged circumferentially around the door body, and the arc-shaped portion is close to the corner of the door body along the circumferential direction.

[0019] In this technical solution, when the airflow channel is arranged around the circumference of the door, compared to placing the arc-shaped part in the middle of one side of the door along the circumference, setting the arc-shaped part close to the corner of the door can reduce the number of corners in the airflow channel, thereby reducing the airflow resistance in the airflow channel.

[0020] Preferably, the airflow channel further includes an air outlet, which is located at the end of the second part away from the first part.

[0021] Preferably, there are multiple vent holes, which are spaced apart along the airflow direction of the airflow channel; the multiple vent holes are of the same size, and the spacing between the vent holes gradually decreases along the airflow direction of the airflow channel.

[0022] In this technical solution, by setting multiple vent holes to the same size, it is easier to process the vent holes. At the same time, by setting the spacing of the vent holes to gradually decrease along the air supply direction, the air volume of the vent holes can be more evenly distributed along the circumference of the door.

[0023] Preferably, there are multiple vent holes, which are spaced apart along the airflow direction of the airflow channel; the vent holes are spaced at the same distance, and the size of the vent holes gradually increases along the airflow direction of the airflow channel.

[0024] In this technical solution, by setting the ventilation holes with the same spacing but gradually increasing size, the air volume of the ventilation holes can be more evenly distributed along the circumference of the door.

[0025] Preferably, the airflow channel is disposed inside the door body and located on the side of the door body closer to the refrigerator body.

[0026] In this technical solution, by setting the airflow channel inside the door, it is less likely that the door will not fit properly with the refrigerator body due to improper installation.

[0027] Preferably, the airflow channel is located near the circumferential edge of the door.

[0028] In this technical solution, by setting the airflow channel close to the circumferential edge of the door, and by keeping both the airflow channel and the vent far away from the refrigeration room, the impact of the air flowing out of the airflow channel on the refrigeration room can be reduced.

[0029] Preferably, the air inlet is located at the bottom of the door.

[0030] Preferably, there are multiple air inlets, and each of the multiple air inlets is equipped with a suction device.

[0031] In this technical solution, by setting multiple air inlets and suction devices, the flow rate and velocity of the supplied air can be increased, thereby improving the anti-condensation effect.

[0032] The positive and progressive effects of this invention are as follows: By setting an airflow channel on the door and incorporating a suction device that operates independently of the compressor, the suction device draws outside air into the airflow channel. This outside air then flows through the vents to the side frame of the refrigerator body. Since the outside air temperature is relatively higher than the cooling compartment, this air can exchange heat with the side frame of the refrigerator body, carrying away the cold air and thus raising the temperature of the side frame. This prevents condensation from forming on the side frame due to a large temperature difference with the room temperature. Because the suction device operates independently of the compressor, it remains operational even when the compressor stops, ensuring the refrigerator maintains its excellent anti-condensation function. Furthermore, since the vents are not connected to the cooling compartment when the door is closed, relatively warm air flowing from the vents is prevented from entering the cooling compartment.

[0051] Suction device 4 Detailed Implementation

[0052] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0053] like Figures 1-6 As shown, this embodiment provides an anti-condensation refrigerator 100, which includes a refrigerator body 1, a door 2, and a compressor, as follows: Figure 1 As shown, the refrigerator body 1 has a refrigeration compartment 101, such as Figure 1 and Figure 2 As shown, the door 2 is provided with an airflow channel 3, which includes an air inlet. An air intake device 4 is installed at the air inlet. The air intake device 4 can operate independently of the compressor. The air intake device 4 is used to draw air from outside the anti-condensation refrigerator 100 into the airflow channel 3. Figure 3 and Figure 4As shown, the airflow channel 3 has a vent 301 penetrating the wall of the airflow channel 3. The vent 301 has an outlet end facing the side frame of the refrigerator body 1, and when the door 2 is closed, the vent 301 is not connected to the cooling compartment 101. By setting the airflow channel 3 on the door 2 and setting a suction device 4 that can operate independently of the compressor, the suction device 4 sends air from outside the anti-condensation refrigerator 100 into the airflow channel 3. The air from outside the refrigerator 100 can flow through the vent 301 to the side frame of the refrigerator body 1. Since the air temperature outside the refrigerator 100 is relatively higher than that in the cooling compartment 101, this air can exchange heat with the side frame of the refrigerator body 1, taking away the cold air from the side frame of the refrigerator body 1, thereby raising the temperature of the side frame of the refrigerator body 1 and preventing condensation from occurring at the side frame of the refrigerator body 1 due to a large temperature difference with the room temperature. Because the suction device 4 can operate independently of the compressor, it remains operational even when the compressor stops, preventing it from ceasing operation and ensuring the refrigerator 100 maintains its excellent anti-condensation function. Simultaneously, since the vent 301 is not connected to the cooling compartment 101 when the door 2 is closed, relatively warm air exiting the vent 301 is prevented from entering the cooling compartment 101, thus reducing the refrigerator 100's energy consumption.

[0054] Furthermore, compared to using a condenser coil that requires refrigerant to achieve the purpose of preventing condensation, using the air outside the refrigerator 100 to achieve the purpose of preventing condensation can reduce the cost of preventing condensation, and the assembly is relatively simple and safer.

[0055] like Figures 4-6 As shown, in this embodiment, the vent 301 is not connected to the refrigeration compartment 101. This is achieved by placing the vent 301 on the outside of the door seal 21 connecting the door body 2 and the refrigerator body 1. Furthermore, in this embodiment, the airflow channel 3 is located near the circumferential edge of the door body 2. By placing the airflow channel 3 near the circumferential edge of the door body 2, both the airflow channel 3 and the vent 301 are far from the refrigeration compartment 101, reducing the impact of air flowing out of the airflow channel 3 on the refrigeration compartment 101.

[0056] In this embodiment, as Figures 1-2 As shown, the airflow channel 3 includes a first part 31 near the air inlet and a second part 32 away from the air inlet. Along the airflow direction of the airflow channel 3, the cross-sectional area of ​​the first part 31 gradually decreases. By setting the first part 31 to have at least a portion of its cross-sectional area gradually decrease along the airflow direction, the air pressure at the end near the air inlet is greater than the air pressure at the end away from the air inlet, which is more conducive to airflow.

[0057] Specifically, in this embodiment, along the airflow direction of the airflow channel 3, the cross-sectional area of ​​the first part 31 near the second part 32 gradually decreases, while the cross-sectional area of ​​the second part 32 remains constant. Furthermore, the dimension of the end of the first part 31 near the second part 32 is equal to the dimension of the second part 32. Compared to setting the second part 32 as a channel with a changing cross-sectional area, setting the cross-sectional area of ​​the second part 32 to remain constant reduces the resistance to airflow within the second part 32. Simultaneously, by setting the dimension of the second part 32 to be equal to the dimension of the end of the first part 31 near the second part 32, abrupt changes at the junction of the first part 31 and the second part 32 are avoided, thus reducing the flow resistance of air in the airflow channel 3.

[0058] Of course, in other embodiments, the entire first part 31 can be configured to have a gradually decreasing cross-sectional area, or the middle position of the first part 31 can be configured to have a gradually decreasing cross-sectional area, etc., which can achieve the purpose of making the wind pressure at the end of the first part 31 closer to the air inlet greater than the wind pressure at the end farther from the air inlet, so as to facilitate air delivery. This will not be elaborated further here.

[0059] In this embodiment, as Figure 2 As shown, the air inlet is located at the end near the first part 31 and away from the second part 32. The suction device 4 is a radial fan. The end of the first part 31 away from the second part 32 has an arc-shaped portion 311, and the radial fan is disposed within the arc-shaped portion 311. The arc-shaped portion 311 is coaxially arranged with the radial fan, and the inner diameter of the arc-shaped portion 311 is larger than the outer diameter of the radial fan. By equipping the suction device 4 with a radial fan and providing an arc-shaped portion 311 that matches the shape of the radial fan, the flow resistance after the radial fan draws air into the airflow channel 3 is reduced.

[0060] At the same time, such as Figure 1 and Figure 2 As shown, one sidewall of the remaining portion of the first part 31 is smoothly connected to one end of the arcuate portion 311. This smooth connection means that the sidewall of the remaining portion of the first part 31, which connects to one end of the arcuate portion 311, extends along the tangential direction of that end. By making one sidewall of the remaining portion of the first part 31 smoothly connected to one end of the arcuate portion 311, the resistance to airflow from the arcuate portion 311 can be reduced.

[0061] Of course, in other embodiments, the suction device 4 can also be other mechanical devices in the prior art that can send air into the airflow channel 3, such as air pumps, axial fans, etc., which will not be described in detail here.

[0062] In this embodiment, as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the airflow channel 3 is arranged circumferentially around the door body 2, and the airflow direction of the airflow channel 3 is along the circumference of the door body. The arc-shaped portion 311 is located near the corner of the door body 2 along the circumference. By arranging the airflow channel 3 circumferentially around the door body 2, air can be delivered to the periphery of the refrigerator body 1, improving the anti-condensation effect. Specifically, compared to placing the arc-shaped portion 311 at the middle of one side of the door body 2 along the circumference, placing the arc-shaped portion 311 near the corner of the door body 2 reduces the number of corners in the airflow channel 3, thereby reducing the airflow resistance in the airflow channel 3.

[0063] Specifically, such as Figure 5 and Figure 6 As shown, a rectangle is typically formed around the circumference of the door body 2, with four corners. When the arc-shaped part 311 is located at a corner of the door body 2, the beginning of the airflow channel 3 is located at one of the corners of the door body 2. As the airflow channel 3 extends circumferentially around the door body 2, it only needs to pass through the remaining three corners to achieve circumferential coverage of the door body 2. However, when the beginning of the airflow channel 3 is located near the middle of any two corners, the airflow channel 3 needs to pass through all four corners to achieve circumferential coverage of the door body 2. The more corners the airflow channel 3 has, the greater the resistance encountered by the airflow as it flows through the airflow channel 3.

[0064] In this embodiment, as Figure 3 and Figure 4 As shown, the airflow channel 3 also includes an air outlet 302, which is located at the end of the second part 32 away from the first part 31.

[0065] Meanwhile, in this embodiment, the air inlet is located at the bottom of the door 2, such as... Figure 5 and Figure 6 As shown, Figure 6 The direction indicated by the thickened arrow on the outer side of the middle door body 2 is the air supply direction, and it is located at... Figure 6 The position is in the lower right corner. In other words, the beginning of airflow channel 3 is located in... Figure 6 The bottom right end of the middle door body 2. Multiple vent holes 301 are provided on the airflow channel 3. These vent holes 301 are spaced apart along the airflow direction of the airflow channel 3, and all vent holes 301 are of the same size. The spacing between the vent holes 301 gradually decreases along the airflow direction of the airflow channel 3. By setting the multiple vent holes 301 to be of the same size, it is easier to manufacture the vent holes 301. At the same time, by setting the spacing between the vent holes 301 to gradually decrease along the airflow direction, the airflow from the vent holes 301 can be more evenly distributed along the circumference of the door body 2.

[0066] Specifically, when air is supplied through the airflow channel 3, the flow rate and air pressure at the end of the airflow channel 3 along the air supply direction will decrease due to the resistance of the airflow channel 3 and the continuous flow of air from the vent 301. By setting the spacing of the vent 301 to gradually decrease along the air supply direction, that is, gradually increasing the density of the vent 301 along the air supply direction, the effect of the decrease in flow rate and air pressure at the end of the airflow channel 3 along the air supply direction can be offset, so that the air volume of the vent 301 can be more evenly distributed along the circumference of the door body 2.

[0067] Of course, in other embodiments, the ventilation holes 301 can also be set to have the same spacing, but the size of the ventilation holes 301 gradually increases along the air supply direction of the airflow channel 3, which can also make the air volume of the ventilation holes 301 more evenly distributed along the circumference of the door body 2, which will not be elaborated here.

[0068] In this embodiment, as Figures 1-4 As shown, the airflow channel 3 is located inside the door body 2, on the side of the door body 2 closest to the refrigerator body 1. The vent 301 penetrates the side wall of the door body 2 near the refrigerator body 1 to deliver air to the side frame of the refrigerator body 1. By placing the airflow channel 3 inside the door body 2, it is less likely that the door body 2 will not fit properly with the refrigerator body 1 due to improper installation.

[0069] In this embodiment, as Figure 1 and Figure 2 As shown, there is one air inlet, located at the bottom of door 2.

[0070] Of course, in other embodiments, multiple air inlets can be provided, and suction devices 4 can be provided at each of the multiple air inlets. Furthermore, the multiple air inlets can be evenly distributed along the circumference of the door body 2. By providing multiple air inlets and suction devices 4, the flow rate and velocity of the supplied air can be increased, thereby improving the anti-condensation effect.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
