Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration, and in particular to an embedded multi-unit refrigerator. Background Technology
[0002] As modern families strive for a higher quality of life, the demand for larger refrigerator capacities is increasing. Traditional single-door or double-door refrigerators are no longer sufficient to meet the food storage needs of large households. Therefore, dual-unit or even multi-unit refrigerator solutions have emerged on the market, aiming to provide more flexible and larger storage space through modular design. However, in built-in multi-unit refrigerators, the adjacent sides of each pair of refrigerators are tightly fitted together. The cold air emitted by the refrigerator cannot effectively diffuse within the narrow, enclosed space, causing the wall temperature to drop. In humid environments, the wall temperature falls below the dew point temperature, causing water vapor in the air to condense into water droplets on the wall surface—condensation. Once condensation forms, if not dealt with promptly, it will gradually accumulate and flow onto the floor.
[0003] The most common solution on the market is to place a whole sheet of heat-absorbing and water-absorbing cotton between two refrigerators. However, the water-absorbing cotton has a limited capacity. Once it reaches saturation, it can no longer absorb more condensation, causing the condensation to drip onto the ground. In addition, the large area of heat-absorbing and water-absorbing cotton significantly increases the cost. Utility Model Content
[0004] To address the aforementioned issues, this application provides an embedded multi-unit refrigerator, comprising at least two refrigerators arranged side by side and an anti-condensation device disposed between each pair of refrigerators. Each pair of refrigerators includes a first side wall and a second side wall facing each other. The anti-condensation device includes a waterproof strip disposed between the first side wall and the second side wall, and together with the first side wall and the second side wall, forms a cavity.
[0005] Furthermore, the waterproof strip is positioned close to the edge of the first sidewall to form a closed loop.
[0006] Furthermore, the anti-condensation device also includes a drain port located at the lower end of the waterproof strip.
[0007] Furthermore, the anti-condensation device also includes a flow guiding device disposed below the drainage port.
[0008] Furthermore, the flow guiding device includes a water collecting head and a flow guiding pipe connected in sequence from the flow inlet.
[0009] Furthermore, the anti-condensation device also includes a water collection box disposed below the flow guiding device.
[0010] Furthermore, the water collection box is the evaporation dish of the right refrigerator in the two adjacent refrigerators.
[0011] Furthermore, the water collection head includes a first wall, a second wall, a third wall, and a fourth wall that are interconnected and arranged in a truncated quadrangular shape. The first wall and the third wall are arranged opposite each other and have a first length along the axis of the water collection head. The second wall and the fourth wall are arranged opposite each other and have a second length along the axis of the water collection head. The first length is less than the second length.

[0014] This application relates to an embedded multi-unit refrigerator, comprising at least two refrigerators arranged side by side and an anti-condensation device disposed between each pair of refrigerators. Each pair of refrigerators includes opposing first and second sidewalls. The anti-condensation device includes a waterproof strip disposed between the first and second sidewalls, forming a cavity together with the first and second sidewalls.

[0030] To provide a better understanding of the purpose, structure, features, and functions of this application, detailed descriptions are provided below with reference to specific embodiments.
[0031] This application provides an embedded multi-unit refrigerator, including at least two refrigerators arranged side by side and an anti-condensation device disposed between each pair of refrigerators. Each pair of refrigerators includes a first side wall 11 and a second side wall 21 facing each other. The anti-condensation device includes a waterproof strip 12, which is disposed between the first side wall 11 and the second side wall 21, and together with the first side wall 11 and the second side wall 21, forms a cavity 13.
[0032] Each refrigerator arranged side by side includes a first sidewall 11 and a second sidewall 21 arranged opposite to each other. Between each two adjacent refrigerators, there is a first sidewall 11 on the left refrigerator 1 and a second sidewall 21 on the right refrigerator 2. The first sidewall 11 and the second sidewall 21 are opposite to each other and a gap is formed between the first sidewall 11 and the second sidewall 21. The waterproof strip 12 is disposed in the gap between the first sidewall 11 and the second sidewall 21 and fits tightly with the first sidewall 11 and the second sidewall 21. That is, the thickness of the waterproof strip 12 is adapted to the distance of the gap from the first sidewall 11 to the second sidewall 21. The waterproof strip 12, the first sidewall 11 and the second sidewall 21 together form a cavity 13.
[0033] The size and shape of the cavity 13 enclosed by the waterproof strip 12, the first side wall 11, and the second side wall 21 are set according to actual needs, and this application does not impose specific restrictions.
[0034] When the waterproof strip 12 is placed between the first side wall 11 and the second side wall 21, it can be fixed by adhesive bonding, slot fixing or screw fixing.
[0035] In one embodiment, the waterproof strip 12 is disposed near the edge of the first sidewall 11 to form a closed loop.
[0036] The waterproof strip 12 is positioned near the edge of the first side wall 11, allowing it to fit more tightly against the refrigerator side wall. Since the thickness of the waterproof strip 12 is adapted to the distance between the first side wall 11 and the second side wall 21, positioning the waterproof strip 12 near the edge of the first side wall 11 can effectively reduce the area of condensation on the first side wall 11 and the second side wall 21.
[0037] The waterproof strips 12 are joined end to end to form a closed loop, ensuring that the entire gap is surrounded and isolated by the waterproof strips 12 without any gaps. The waterproof strips 12 are set as a closed loop, which can more effectively prevent the cold air inside the refrigerator from spreading to the adjacent space through the gap, and maintain the temperature inside the refrigerator. At the same time, the waterproof strips 12 effectively prevent the air outside the gap from entering the gap, reducing the risk of condensation on the first side wall 11 and the second side wall 21.
[0038] The anti-condensation device also includes a drain port located at the lower end of the waterproof strip 12.
[0039] When condensation occurs on the first sidewall 11 and the second sidewall 21 during refrigerator operation, the condensation increases over time, producing condensate water. The condensate water slides down the first sidewall 11 and the second sidewall 21 under its own gravity to the lowest waterproof strip 12 and is then drained to the drain port. The drain port has a one-way drainage function, ensuring that the condensate water is guided to a specific location in one direction, making the collection and discharge of condensate water more concentrated and easier to clean.
[0040] The drainage port can be formed by breaking the waterproof strip 12 at its lowest end, or the drainage port can be set to a specific shape according to actual needs.
[0041] The anti-condensation device also includes a flow guiding device disposed below the drainage port.
[0042] The flow guiding device is located below the inlet to ensure that the condensate can flow in smoothly. When condensate flows in, the flow guiding device can quickly and accurately guide the condensate flowing out of the inlet to a predetermined location, such as a drain trough, a water collection box, or an external drainage pipe.
[0043] The shape and size of the diversion device need to be designed according to the flow rate and drainage requirements of the diversion port. For example, the diversion device can be trough-shaped or pipe-shaped.
[0044] In an optional embodiment, the flow guiding device includes a water collecting head 141 and a flow guiding pipe 142 connected in sequence from the flow inlet.
[0045] The water collection head 141 is located below the inlet to quickly collect the condensate flowing out of the inlet. The water collection head 141 can be designed as a funnel or a bowl with different diameters at both ends to increase the collection area and improve collection efficiency.
[0046] The guide pipe 142 is connected to the water collecting head 141, guiding the condensate collected by the water collecting head 141 to a predetermined location, such as a drain trough, a water collection box, or an external drainage pipe. The guide pipe 142 is configured with a certain slope and inner diameter to ensure that the condensate can flow smoothly and avoid blockage.
[0047] When condensation occurs during refrigerator operation, it flows along the waterproof strip 12 to the drain port. At the drain port, the condensation is quickly collected by the water collection head 141 and guided to the drainage system through the guide pipe 142. Throughout the process, the water collection head 141 and the guide pipe 142 work together to ensure the effective collection and drainage of condensation.
[0048] The anti-condensation device also includes a water collection box 15 located below the flow guiding device.
[0049] The water collection box 15 is located below the flow guiding device to collect the condensate discharged from the flow guiding channel or the flow guiding pipe 142. The condensate is collected by gravity, preventing water droplets from dripping directly onto the equipment surface or the ground.
[0050] Specifically, the water collection box 15 is located below the flow guide pipe 142 of the flow guide device.
[0051] The water collection box 15 is the evaporation dish of the right refrigerator 2 in the two adjacent refrigerators.
[0052] The evaporation dish is placed near the refrigerator compressor. The condensate is guided to the evaporation dish by the guide device. The heat generated by the compressor during operation can be used to heat and evaporate the collected condensate, preventing water accumulation. At the same time, the low-temperature condensate entering the evaporation dish can effectively cool the refrigerant discharged by the compressor and improve the refrigeration efficiency.
[0053] The water collection box 15 is the evaporator of the right refrigerator 2. This is mainly because in every two refrigerators side by side, the air inlet of the right refrigerator 2 is close to the air outlet of the left refrigerator 1. This causes some of the high-temperature gas discharged from the air outlet of the left refrigerator 1 to flow back to the air inlet of the right refrigerator 2, resulting in an increase in the surface temperature of the evaporator of the right refrigerator 2 and a decrease in cooling efficiency. The condensate flows into the evaporator of the right refrigerator 2, and the evaporation of the condensate absorbs additional heat to compensate for the loss of cooling capacity of the right refrigerator 2 caused by the gas backflow, thereby improving the cooling efficiency of the right refrigerator 2.
[0054] The refrigerator on the right is the refrigerator located on the user's right when the user is facing the refrigerator door.
[0055] In an optional embodiment, the water collecting head 141 includes a first wall 161, a second wall 162, a third wall 163, and a fourth wall 164 that are interconnected and arranged in a frustum shape. The first wall 161 and the third wall 163 are disposed opposite each other and have a first length L1 along the axial direction of the water collecting head 141. The second wall 162 and the fourth wall 164 are disposed opposite each other and have a second length L2 along the axial direction of the water collecting head 141. The first length L1 is less than the second length L2. The first wall 161 and the third wall 163 are respectively attached to the first side wall 11 and the second side wall 21.
[0056] The truncated pyramidal water collection head 141, formed by the first wall 161, the second wall 162, the third wall 163, and the fourth wall 164, has an overall trapezoidal converging structure. A drain outlet 165 is provided at the convergence point of the water collection head 141, which connects to the guide pipe 142. The first wall 161 and the third wall 163 are respectively tightly attached to the first side wall 11 and the second side wall 21 to ensure that condensate flowing down the first side wall 11 and the second side wall 21 can smoothly flow to the water collection head 141, and then sequentially through the drain outlet 165 of the water collection head 141 and the guide pipe 142 to the water collection box 15. The second wall 162 and the fourth wall 164 are relatively long and connect to the waterproof strip 12, forming a longer sealing contact surface, effectively preventing condensate from flowing out from the junction of the waterproof strip 12 and the water collection head 141.
[0057] The waterproof strip 12 is disposed close to the first side wall 11 and the second side wall 21, and the path of the waterproof strip 12 forms a U-shape.
[0058] The waterproof strip 12 is disposed close to the first sidewall 11 and the second sidewall 21. That is, the waterproof strip 12 is disposed in the gap between the first sidewall 11 and the second sidewall 21, and is tightly fitted to the first sidewall 11 and the second sidewall 21. The waterproof strip 12 is configured to be close to the front edge, the rear edge, and the bottom edge of the gap, forming a U-shaped or similar U-shaped path.
[0059] The U-shaped waterproof strip 12 isolates the air outside the gap to a certain extent, reducing condensation on the first side wall 11 and the second side wall 21 of the refrigerator. At the same time, it releases a cavity 13 at the upper edge of the gap, allowing a small amount of air outside the gap to enter the cavity 13 and generate a small amount of condensation. The small amount of condensation flows to the refrigerator evaporator, which improves the refrigerator's cooling efficiency to a certain extent.
[0060] The waterproof strip 12 can be made of materials with good waterproof and sealing properties, such as PVC, silicone rubber, and neoprene rubber. The specific choice depends on the actual needs, and this application does not impose any specific restrictions.
[0061] In an optional embodiment, a baffle is also provided below the anti-condensation device between each pair of refrigerators to prevent gas backflow between the two refrigerators, specifically, the high-temperature gas from the air outlet of the left refrigerator 1 flows back to the air inlet of the right refrigerator 2.
[0062] Specifically, a baffle is positioned below the cavity 13 formed by the waterproof strip 12, the first side wall 11, and the second side wall 21. The baffle's dimensions, from the front to the rear of the refrigerator, are adapted to the width of the first side wall 11 of the left refrigerator 1 and / or the second side wall 21 of the right refrigerator 2. The baffle acts as a physical barrier, preventing the convection of hot and cold air between the left refrigerator 1 and the right refrigerator 2, thereby improving the cooling efficiency of the right refrigerator 2 to some extent.
[0063] The front side of the refrigerator refers to the refrigerator door, and the rear side of the refrigerator refers to the side wall opposite the refrigerator door when the refrigerator door is closed.
[0064] It should be noted that this application uses a two-unit refrigerator as an example to illustrate the technical solution. Those skilled in the art should understand that the technical solution in this application is also applicable to multi-unit refrigerators with more than two refrigerators.
[0065] This application relates to an embedded multi-unit refrigerator, comprising at least two refrigerators arranged side by side and an anti-condensation device disposed between each pair of refrigerators. Each pair of refrigerators includes a first sidewall 11 and a second sidewall 21 facing each other. The anti-condensation device includes a waterproof strip 12 disposed between the first sidewall 11 and the second sidewall 21, forming a cavity 13 together with the first sidewall 11 and the second sidewall 21. By providing a waterproof strip 12 between each pair of refrigerators, this application effectively prevents outside air from entering the narrow, enclosed space when the cold energy emitted by the refrigerator cannot effectively diffuse within it, thus avoiding condensation. Furthermore, the waterproof strip 12 does not need to cover the entire adjacent gap, effectively reducing costs.
