[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] It should be noted that the refrigeration device of this embodiment can be a refrigerator, a freezer or a wine cabinet, which can be understood as a device with a refrigeration function. In the following embodiments, the refrigeration device is mainly described as a refrigerator.

[0038] Reference Figure 1 As shown, it is a refrigerator 1000 of an embodiment of the utility model, and the refrigerator 1000 includes a door body 200 and a box body 300, wherein the door body 200 is located at the front side of the box body 300, and the door body 200 is rotatably connected to the box body 300. The box body 300 is provided with a storage space 310, an installation bin 320 and an evaporator bin 300, wherein the installation bin 320 and the evaporator bin 300 are both located directly below the storage space 310, and the installation bin 320 is located on a side of the evaporator bin 300 close to the door body 200. It can also be understood that the evaporator bin 300 is located relatively far back, and the installation bin 320 is located relatively far forward, and the highest point of the evaporator bin 300 is higher than the highest point of the evaporator bin 300, so that the distance from the evaporator bin 300 to the installation bin 320 in the up-down direction can be shortened. In the front-back direction, the length of the evaporator bin 300 can be greater than the length of the installation bin 320.

[0039] It should be noted that in the above embodiment, the space for storing things in the cabinet 300 of the refrigerator 1000 is collectively referred to as the storage space 310, that is, the storage space 310 may refer to a single chamber or the sum of multiple chambers. Figure 1 As shown, in some embodiments, the storage space 310 includes a refrigerating chamber 311, a temperature-changing chamber 312, and a freezing chamber 313 arranged in sequence from top to bottom. It should be noted that, in some other embodiments, the storage space 310 may also include only the refrigerating chamber 311 and the freezing chamber 313, or only one of the refrigerating chamber 311, the temperature-changing chamber 312, and the freezing chamber 313. In this embodiment, the storage space 310 is the freezing chamber 313, and the installation bin 320 and the evaporator bin 300 are both located directly below the freezing chamber 313 to achieve a freezing effect.

[0040] Reference Figure 2 , Figure 3 and Figure 4 As shown, the refrigerator 1000 also includes an evaporator 100, a water collecting pan 400 and a drain pipe 500. The evaporator 100 is located in the evaporator bin 300, the water collecting pan 400 is located in the installation bin 320, and a drain port 331 is provided on the side of the evaporator bin 300 close to the installation bin 320. The drain pipe 500 includes a connecting portion 510 and a pipe portion 520. The connecting portion 510 is connected to the outer wall of the evaporator bin 300, the pipe portion 520 is penetrated through the side wall of the installation bin 320 and is connected to the drain port 331, and the installation bin 320 is provided with a through hole for the pipe portion 520 to penetrate. The connecting portion 510 mainly serves the function of fixed connection, so that the drain pipe 500 is stably connected to the evaporator bin 300, and the drain pipe 500 is not easily separated from the evaporator bin 300. The pipe portion 520 is used to drain the defrost water flowing out of the drain port 331 to the water receiving tray 400. The water receiving tray 400 is placed on the bottom wall of the installation bin 320, and the water receiving tray 400 is located below the pipe portion 520.

[0041] In some embodiments, the installation bin 320 is provided with a front side panel, which is located on the side of the installation bin 320 close to the door body 200. The front side panel is detachable and can be directly disassembled in front of the refrigerator 1000 to open the installation bin 320, take out the water collecting tray 400 in the installation bin 320, and directly pour out the defrost water in the water collecting tray 400.

[0042] In some embodiments, the refrigerator 1000 further includes a condenser, and the installation chamber 320 can be used to install the condenser. Specifically, the condenser is arranged in the water receiving tray 400, and the condenser is in direct contact with the defrost water in the water receiving tray 400. The heat of the condenser can evaporate the heat in the water receiving tray 400. The installation chamber 320 can also be understood as a compressor chamber. The refrigerator 1000 further includes a compressor. The compressor and the condenser are located in the installation chamber 320, and the defrost water can be evaporated by the heat of the compressor and the condenser. The installation chamber 320 can be located at the rear side of the evaporator chamber 300, or the installation chamber 320 can be located below the evaporator chamber 300. Figure 1 and Figure 2 As shown, in some embodiments, the installation bin 320 is located at the front side of the evaporator bin 300, and the installation bin 320 is located relatively forward, and the installation bin 320 does not protrude upward, so that the storage space 310 above the installation bin 320 can be relatively regular, which is conducive to fully utilizing the storage space 310. When the drawers are arranged in the storage space 310, the drawers can extend in the front-to-back direction to increase the depth of the drawers and make the drawers have a larger capacity. A fan can also be arranged in the installation bin 320, and the fan can dissipate heat for the compressor or condenser. The airflow blown by the fan can also pass through the surface of the defrost water to accelerate the evaporation rate of the defrost water.

[0043] It is understandable that, referring to Figure 4 As shown, in some embodiments, the bottom wall of the evaporator bin 300 is inclined, and the end of the bottom wall of the evaporator bin 300 away from the installation bin 320 is higher than the end of the bottom wall of the evaporator bin 300 close to the installation bin 320, so that the defrost water in the evaporator bin 300 accumulates at the end of the evaporator bin 300 close to the installation bin 320. It can also be understood that the rear end position of the bottom wall of the evaporator bin 300 is higher than the front end position, and the drain port 331 is located at the lowest point of the evaporator bin 300. It can also be understood that the drain port 331 is located at the corner position of the evaporator bin 300, so that the drain port 331 can smoothly discharge the accumulated defrost water. It should be noted that in this embodiment, the drain port 331 is located at the lowest point of the evaporator bin 300. At the same time, the drain port 331 is set toward the installation bin 320. It can also be understood that the drain port 331 is located at the front side of the evaporator bin 300, which can shorten the distance from the drain port 331 to the water receiving tray 400 in the front-to-back direction.

[0044] Reference Figure 2 As shown, in some embodiments, the evaporator 100 is placed on the bottom wall of the evaporator bin 300, so that the evaporator 100 is in an inclined state, and the end of the evaporator 100 away from the installation bin 320 is higher than the end of the evaporator 100 close to the installation bin 320. When the refrigerator 1000 is in the defrost mode, due to the action of gravity, the defrost water on the evaporator 100 can gather to the lower end of the evaporator 100, which can help the evaporator 100 drain the defrost water and avoid defrost water remaining on the evaporator 100.

[0045] In some embodiments, a fastener may be used to connect the connection portion 510 and the evaporator bin 300 by screwing or riveting. The fastener may be a screw or a rivet. The connection portion 510 and the evaporator bin 300 may also be connected by providing a buckle structure on the connection portion 510 and the evaporator bin 300. The connection portion 510 and the evaporator bin 300 may also be connected by bonding or other methods.

[0046] It is understandable that, referring to Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, the outer wall of the evaporator bin 300 is provided with a convex portion 332, and the connecting portion 510 can be constructed as a groove body, and the groove body is covered by the convex portion 332. It can also be understood that the connecting portion 510 surrounds the convex portion 332. Specifically, the bottom wall of part of the evaporator bin 300 extends downward to form the convex portion 332. From the side, it can also be understood that the connecting portion 510 is bent into a roughly U-shaped structure to form the above-mentioned groove body, and the top of the connecting portion 510 contacts the bottom of the convex portion 332. The connecting portion 510 surrounds the convex portion 332, making it difficult for the connecting portion 510 to move forward and backward. It can be understood that the connecting portion 510 has a certain elasticity, and the connecting portion 510 can produce local deformation. The connecting portion 510 is buckled with the convex portion 332, and the drain pipe 500 can be fixed to the evaporator bin 300 without fastener structures such as screws, and the installation operation is relatively convenient.

[0047] In some embodiments, the connection portion 510 may also be constructed as a protruding structure, and the outer wall of the evaporator bin 300 is provided with a groove body, and the connection portion 510 cooperates with the groove body to connect the connection portion 510 and the evaporator bin 300 together.

[0048] It is understood that in some embodiments, the connecting portion 510 and the tube portion 520 are an integral structure, and the connecting portion 510 and the tube portion 520 can be manufactured by an integral molding process. Alternatively, the connecting portion 510 and the tube portion 520 can be two independent parts, and the connecting portion 510 and the tube portion 520 can be connected together by a fastener or a snap-fit ​​structure.

[0049] It is understandable that, referring to Figure 4 As shown, in some embodiments, the side of the protrusion 332 away from the connection part 510 forms a water collecting groove 333, and the water collecting groove 333 is located in the evaporator bin 300. The bottom wall of the evaporator bin 300 is inclined, one end of the bottom wall is higher, and the other end is lower. The water collecting groove 333 is located on the lower side of the bottom wall. It can also be understood that the water collecting groove 333 is located at the front side of the evaporator bin. It can also be understood that since the protrusion 332 extends downward, the upper side of the protrusion 332 naturally forms the water collecting groove 333. The water collecting groove 333 can be used to collect the defrost water of the evaporator 100. Since the bottom wall of the evaporator bin 300 is inclined, the defrost water in the evaporator bin 300 will gradually gather into the water collecting groove 333 under the action of gravity, so as to prevent the defrost water from remaining near the evaporator 100. In addition, the height of the water collecting tank 333 is lower than the height of the evaporator 100 . When defrost water is stored in the water collecting tank 333 , the defrost water can be prevented from touching the evaporator 100 .

[0050] It should be noted that there is a certain space between the bottom wall of the evaporator bin 300 and the bottom wall of the box body 300, which allows the protrusion 332 to extend downward to form a water collecting trough 333, so that the space there can be fully utilized.

[0051] Reference Figure 4 As shown, in some embodiments, the bottom wall of the water collecting tank 333 is inclined, and the bottom wall of the water collecting tank 333 is higher on the side close to the evaporator 100, and is lower on the side close to the drain port 331. Under the action of gravity, the defrost water in the water collecting tank 333 will automatically flow toward the drain port 331, which is conducive to draining the defrost water and avoiding the defrost water from remaining in the water collecting tank 333.

[0052] It is understandable that, referring to Figure 2 and Figure 6 As shown, in some embodiments, the drain pipe 500 further includes a positioning portion 530, which is connected to the pipe portion 520, protrudes from the outer peripheral wall of the pipe portion 520, has a width greater than the width of the pipe portion 520, and is located outside the installation chamber 320. When part of the structure of the pipe portion 520 penetrates into the installation chamber 320, if the pipe portion 520 moves toward the installation chamber 320, the positioning portion 530 will abut against the outer side wall of the installation chamber 320, thereby limiting the movement of the pipe portion 520, playing a limiting role, and maintaining the position of the drain pipe 500. From the side, the positioning portion 530 is a sheet-like structure, and the positioning portion 530 is parallel or substantially parallel to the outer side wall of the installation chamber 320 near the positioning portion 530. In some embodiments, the positioning portion 530 can be an annular structure, and the outer diameter of the positioning portion 530 is greater than the outer diameter of the outer peripheral wall of the pipe portion 520. Alternatively, the positioning portion 530 can also be a square structure or other irregularly shaped structures.

[0053] It is understandable that, referring to Figure 2 and Figure 4 As shown, in some embodiments, a connecting pipe 334 is provided on one side of the evaporator bin 300 close to the installation bin 320, and the connecting pipe 334 extends toward the installation bin 320. The end of the connecting pipe 334 close to the installation bin 320 forms the above-mentioned drain port 331, and the cross-section of the connecting pipe 334 is circular. The connecting pipe 334 is passed through the pipe portion 520. It can also be understood that the connecting pipe 334 extends into the pipe portion 520, and the outer peripheral wall of the connecting pipe 334 abuts against the inner peripheral wall of the pipe portion 520, which can play a limiting role. When draining water, the connecting pipe 334 and the pipe portion 520 can be stably connected together without shaking around.

[0054] It should be noted that the evaporator bin 300 and the connecting pipe 334 can be an integral structure made through an integrated molding process, and the drain pipe 500 and the connecting pipe 334 are two independent structures. In this embodiment, the drain pipe 500 is set. The drain pipe 500 and the connecting pipe 334 do not need to directly drain the defrost water to the water receiving tray 400 through the connecting pipe 334, so the length of the connecting pipe 334 can be shortened. It is more convenient to install the evaporator bin 300. The evaporator bin 300 can be installed first and then the drain pipe 500 can be installed.

[0055] It is understandable that, referring to Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the connection portion 510 includes a first section 511, a second section 512, and a third section 513 connected in sequence from front to back, the first section 511 and the third section 513 extend upward, the second section 512 is arranged approximately horizontally, and in the up-down direction, the length of the first section 511 is less than the length of the third section 513. The length of the first section 511 is small, which can facilitate subsequent disassembly operations, and the third section 513 is connected to the pipe portion 520. When installing the drain pipe 500 and the connection pipe 334, first insert the connection pipe 334 into the pipe portion 520, the third section 513 will contact the outer side wall of the protrusion 332, and then, directly tighten the connection portion 510 upward, so that the first section 511 and the second section 512 are in contact with the outer side wall of the protrusion 332. When disassembling the drain pipe 500 and the connecting pipe 334 , the first section 511 can be bent downward with force to make the first section 511 and the second section 512 separate from the protrusion 332 , and then the drain pipe 500 can be taken out forward to separate the third section 513 from the protrusion 332 , and the drain pipe 500 is separated from the connecting pipe 334 .

[0056] It is understandable that, referring to Figure 4 As shown, in some embodiments, the minimum horizontal distance between the lowest point of the drain outlet 331 and the water receiving pan 400 is L1, and L1 satisfies: 30mm≤L1≤60mm. L1 can also be understood as the minimum distance between the lowest point of the drain outlet 331 and the water receiving pan 400 in the front-to-back direction. The size of L1 reflects the length of the drain pipe 500. The smaller L1 is, the smaller the length of the drain pipe 500 is. It can also be understood that this embodiment shortens the distance from the evaporator bin 300 to the water receiving pan 400 by arranging the water receiving pan 400 at the front side of the evaporator bin 300, and can achieve the effect of 30mm≤L1≤60mm, so that the length of the drain pipe 500 is shorter and the drainage is smoother.

[0057] It is understandable that, referring to Figure 4As shown, in some embodiments, the minimum horizontal distance between the lowest point of the drain outlet 331 and the end surface of the cabinet 300 close to the door body 200 is L2, and L2 satisfies: 220mm≤L2≤250mm. L2 can also be understood as the minimum distance between the lowest point of the drain outlet 331 and the end surface of the cabinet 300 close to the door body 200 in the front-to-back direction. It can also be understood that this embodiment shortens the distance from the evaporator bin 300 to the drain tray 400 by arranging the drain tray 400 at the front side of the evaporator bin 300, and can achieve the effect of 220mm≤L2≤250mm, so that the installation bin 320 is closer to the evaporator bin 300, so that the length of the drain pipe 500 is shorter, and the drainage is smoother. At the same time, the larger L2 also ensures that the installation space of the installation bin 320 is larger and can accommodate the lower drain tray 400.

[0058] It is understandable that, referring to Figure 6 As shown, in some embodiments, after the drain pipe 500 is installed and fixed, the horizontal length of the pipe portion 520 is L3, and L3 satisfies: 65mm≤L3≤80mm. It can also be understood that the length of the pipe portion 520 in the front-to-back direction is L3, and the length of L3 is small, so that the length of the drain pipe 500 is small, and the drainage is not easy to be blocked. It should be noted that the minimum value of L3 is greater than the maximum value of L1 in the above embodiment, indicating that the length of the drain pipe 500 in the front-to-back direction is greater than the distance from the lowest point of the drain port 331 to the water receiving tray 400. It can also be understood that the water outlet end of the drain pipe 500 will extend to the top of the water receiving tray 400, ensuring that the defrost water flowing out of the drain pipe 500 just drips into the water receiving tray 400 and does not drip outside the water receiving tray 400.

[0059] Reference Figure 2 and Figure 6 As shown, in some embodiments, the pipe portion 520 can be arranged at an angle, and the position of the side of the pipe portion 520 close to the drain outlet 331 is higher than the position of the side of the pipe portion 520 close to the water receiving tray 400, which is conducive to the defrost water in the pipe portion 520 to flow toward the water receiving tray 400 and avoid the defrost water remaining in the pipe portion 520.

[0060] It is understandable that, referring to Figure 6 As shown, in some embodiments, the pipe portion 520 includes a first pipe segment 521 and a second pipe segment 522 connected to each other, at least part of the first pipe segment 521 is passed through the side wall of the installation bin 320, and the second pipe segment 522 is connected to the drain port 331. The first pipe segment 521 and the second pipe segment 522 can be regular cylindrical structures, or the first pipe segment 521 and the second pipe segment 522 can be roughly cylindrical structures.

[0061] Reference Figure 6As shown, in some embodiments, along the direction from the drain outlet 331 to the first pipe segment 521, which can also be understood as along the direction from back to front, the inner hole area of ​​the second pipe segment 522 decreases. The inner hole of the second pipe segment 522 can be circular, elliptical, or other irregular shapes that are roughly annular. The inner hole area of ​​the second pipe segment 522 can be understood as the area of ​​the inner hole cross section of the second pipe segment 522. Along the direction from the drain outlet 331 to the first pipe segment 521, the area of ​​the inner hole cross section of the second pipe segment 522 decreases continuously. For example, referring to Figure 6 As shown, the cross-sectional position at BB is closer to the drain port 331 than the cross-sectional position at CC. Figure 8 and Fig. 9 The inner hole area cut out at BB of the second pipe segment 522 is larger than the inner hole area cut out at CC of the second pipe segment 522. The inner hole area can also be understood as the flow area. Along the direction from the drain port 331 to the first pipe segment 521, the flow area of ​​the second pipe segment 522 gradually decreases. Figure 7 As shown, it can also be understood that the width of the inner peripheral wall of the second pipe section 522 is W, and W decreases continuously along the direction from the drain port 331 to the first pipe section 521. Figure 7 As shown, it can also be understood that the inner diameter of the second pipe section 522 is W, and W is continuously reduced along the direction from the drain port 331 to the first pipe section 521. According to the Bernoulli principle, the inner hole area of ​​the second pipe section 522 is gradually reduced, so that the flow rate of the defrost water can be gradually increased, so that the defrost water can be quickly discharged into the water receiving tray 400, the drainage speed is accelerated, and blockage is avoided. In addition, it should be noted that when the installation chamber 320 is a compressor chamber, the humidity of the airflow in the installation chamber 320 is relatively high and the temperature is relatively high. The high-humidity and high-temperature airflow in the installation chamber 320 is easy to enter the evaporator chamber 330 from the drain pipe 500. If this part of the airflow contacts the evaporator 100, it will be easy to frost on the evaporator 100. In this embodiment, by gradually reducing the inner hole area of ​​the second pipe section 522, the airflow in the installation chamber 320 is not easy to enter the evaporator chamber 330 from the drain pipe 500, and the problem of high-humidity and high-temperature airflow frosting on the evaporator 100 can be alleviated.

[0062] In some embodiments, the inner hole area of ​​the first pipe segment 521 is less than or equal to the minimum inner hole area of ​​the second pipe segment 522. It can also be understood that the inner diameter of the inner peripheral wall of the first pipe segment 521 is less than or equal to the minimum inner diameter of the inner peripheral wall of the second pipe segment 522. Along the direction from the drain port 331 to the first pipe segment 521, the inner hole area of ​​the first pipe segment 521 can be gradually reduced or unchanged. In short, the inner hole area of ​​the first pipe segment 521 is made smaller. According to the Bernoulli principle, the flow rate of the defrosting water in the first pipe segment 521 can be gradually increased, and the drainage speed can be accelerated. At the same time, it is not easy for the airflow in the installation chamber 320 to enter the evaporator chamber 330 from the drain pipe 500, which can alleviate the problem of frost on the evaporator 100 caused by the high humidity and high temperature airflow.

[0063] Reference Figure 6 As shown, in some embodiments, the positioning portion 530 is located between the first pipe section 521 and the second pipe section 522. It can also be understood that the positioning portion 530 divides the pipe section 520 into the first pipe section 521 and the second pipe section 522. When the first pipe section 521 is inserted into the installation chamber 320, the positioning portion 530 can play a positioning role to prevent the second pipe section 522 from extending into the installation chamber 320. The positioning portion 530 can also prevent the high-humidity and high-temperature airflow in the installation chamber 320 from flowing out of the installation chamber 320 through the gap between the first pipe section 521 and the installation chamber 320.
