Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a defrost water containment structure and a refrigerator. Background Technology

[0002] During the refrigeration cycle of a refrigerator, frost forms on the evaporator surface due to low-temperature operation. The defrost water generated during the defrosting stage needs to be collected and treated using a dedicated structure. Traditional designs commonly employ a drip tray solution, which integrates the evaporator pipes inside to improve evaporation efficiency. However, for pure freezers or refrigerators with large cooling capacities, the overall size of the evaporator increases significantly, and its pipe structure inevitably extends into the drip tray area, drastically reducing the effective capacity of the drip tray. When the defrost water volume exceeds the reduced capacity limit, the defrost water easily overflows from the edge of the drip tray, causing liquid leakage into the external environment. This can not only create safety hazards such as slippery floors but also contaminate surrounding equipment or stored items. Furthermore, due to the physical constraints of the refrigerator's compact structure, the geometric dimensions of the drip tray cannot be improved by simply expanding its capacity, making the defrost water overflow problem particularly prominent and difficult to eradicate in large refrigeration equipment. Existing technologies fail to effectively reconcile the contradiction between evaporator layout and drip tray volume, resulting in persistently insufficient reliability in defrost water management. Utility Model Content

[0003] Therefore, it is necessary to provide a defrost water containing structure and a refrigerator to solve the problem that defrost water easily overflows from the drip tray in existing pure freezers or refrigerators with large cooling capacity.

[0004] The defrost water containing structure provided in this application can utilize the heat generated by the compressor and evaporator coil assembly inside the refrigerator to accelerate the evaporation of defrost water. The defrost water containing structure includes a first water tray and a second water tray. The first water tray is used to contain defrost water and is installed on one side of the compressor. The second water tray is used to contain defrost water and is located on one side of the evaporator coil assembly.

[0009] In one embodiment, the defrosting water containing structure further includes an overflow pipe. The first water receiving tray is provided with a first receiving groove. One end of the overflow pipe is connected to the bottom wall of the first receiving groove, and the other end extends toward the opening of the first receiving groove. The overflow pipe is provided with an overflow hole, and the maximum height of the overflow hole is lower than the minimum height of the opening of the first receiving groove.

[0010] The bottom wall of the first receiving tank is provided with a through hole, and a connecting pipe is connected to the bottom of the through hole. The first receiving tank, overflow hole, through hole and connecting pipe are connected in sequence.

The baffle tube is connected to the inner wall of the second containing tank and covers the outer periphery of the clamp head through the baffle hole, so that the connecting tube can connect to the second containing tank through the baffle hole.

[0013] In one embodiment, the card head includes a first card plate and a second card plate, which are cross-arranged and fixedly connected, and the connecting pipe communicates with the flow-blocking hole through the gap between the first card plate and the second card plate.

[0015] In one embodiment, the first water receiving tray is provided with a first receiving groove, and the bottom wall of the first water receiving tray is recessed into the first receiving groove so that the side of the first water receiving tray facing the compressor forms a concave structure to adapt to the shape of the compressor.

Detailed Implementation

[0026] Please see Figures 1-6This application proposes a defrost water containing structure that utilizes the heat from the refrigerator compressor 100 and evaporator coil assembly 200 to accelerate the evaporation of defrost water. The defrost water containing structure includes a first drip tray 300 and a second drip tray 400. The first drip tray 300 is used to contain defrost water and is installed on one side of the compressor 100 to accelerate the evaporation rate of the defrost water in the first drip tray 300 through the heat generated by the compressor 100. The second drip tray 400 is also used to contain defrost water and is located on one side of the evaporator coil assembly 200 to accelerate the evaporation rate of the defrost water in the second drip tray 400 through the heat generated by the evaporator coil assembly 200.

[0027] It should be noted that the defrost water containment structure can be understood as a device specifically designed to handle the water generated during the defrosting process of a refrigerator. Its main function is to achieve rapid evaporation of defrost water through physical layout and heat source utilization. Specifically, the installation position of the first drip tray 300 can be selected on the side of the compressor 100 or in other areas close to the compressor 100, such as behind or above the compressor 100, to ensure effective reception of the heat dissipated by the compressor 100 during operation. Furthermore, the shape of the first drip tray 300 can be designed as rectangular, circular, or other geometric shapes adapted to the space around the compressor 100 to better utilize the space layout of the compressor 100 compartment. For the second drip tray 400, its position can be below or close to the evaporator tube assembly 200, such as to the side or directly below the evaporator tube assembly 200, to ensure direct reception of the heat released by the evaporator tube assembly 200 during the defrosting process. In addition, the material of the second drip tray 400 can be selected as a material with good thermal conductivity, such as metal or specific types of composite materials, thereby further improving heat transfer efficiency.

[0028] The concept of this application lies in using a double drip tray design to distribute the defrost water collection and evaporation process into two independent areas. These areas utilize the natural heat distribution characteristics of the compressor 100 and the evaporator coil assembly 200 inside the refrigerator, respectively, thus solving the problem of defrost water overflow caused by limited drip tray space in existing technologies. This design not only avoids the evaporator occupying storage space but also achieves efficient defrost water processing by rationally utilizing the inherent heat sources inside the refrigerator, thereby reducing the possibility of defrost water leakage.

[0029] The working principle of this embodiment is as follows: A defrost water containing structure, by setting a first drip tray 300 and a second drip tray 400, utilizes the heat from the compressor 100 and the evaporator coil assembly 200 inside the refrigerator to accelerate the evaporation process of defrost water. It should be noted that the first drip tray 300 is installed on one side of the compressor 100 to contain defrost water, and the heat generated by the compressor 100 during operation increases the evaporation rate of the defrost water in the first drip tray 300. Specifically, the compressor 100 continuously emits heat during operation, and the position design of the first drip tray 300 allows it to directly absorb this heat, thereby significantly accelerating the evaporation efficiency of the defrost water. This design fully utilizes the relatively independent and concentrated heat characteristics of the compressor 100 compartment, avoiding the problem of insufficient holding capacity caused by the evaporator occupying space. Furthermore, the second drip tray 400 is located on one side of the evaporator coil assembly 200, also used to contain defrost water, and the heat released by the evaporator coil assembly 200 during the defrost cycle accelerates the evaporation of the defrost water. The evaporator tube assembly 200 generates heat during defrosting, and the placement of the second drip tray 400 allows it to utilize this heat nearby, shortening the flow path of the defrost water and reducing the risk of accumulation. As a result, the defrost water can evaporate quickly near the evaporation source, effectively alleviating the problem of compressed storage space caused by the evaporator being embedded in the drip tray in existing technologies.

[0030] In a further embodiment, such as Figure 2 As shown, the first drip tray 300 is installed at a higher height inside the refrigerator than the second drip tray 400. In practical applications, the first drip tray 300 can be installed above the second drip tray 400 using brackets, fasteners, or other means, thus creating a height difference. This height difference is designed to utilize gravity to allow defrost water to flow naturally, preventing overflow due to excessive accumulation. Furthermore, this design requires no additional power source, simply and reliably expanding the overall storage space.

[0031] Specifically, the height difference between the first drip tray 300 and the second drip tray 400 ensures that when the defrost water in the first drip tray 300 reaches a certain amount, it can automatically flow to the second drip tray 400. Furthermore, the first drip tray 300 is typically positioned above the compressor 100, while the second drip tray 400 is located at the bottom of the refrigerator; this layout makes full use of the internal space of the refrigerator. In addition, the introduction of the connecting pipe 500 further enhances the connection between the two drip trays, allowing defrost water to smoothly transfer from the first drip tray 300 to the second drip tray 400. This technical solution not only effectively solves the problem of defrost water overflow but also improves the efficiency and reliability of defrost water management, making it particularly suitable for pure freezers or refrigerators with large cooling capacities.

[0032] Furthermore, by positioning the first drip tray 300 directly above the compressor 100, the rising characteristic of hot air naturally generated during compressor 100 operation is fully utilized. Since the compressor 100 continuously generates heat during operation, the hot air is conducted upwards. Placing the first drip tray 300 above allows heat to act directly on the bottom of the drip tray via the shortest path, significantly improving the evaporation efficiency of defrost water. This design avoids heat loss during the transfer process, ensuring rapid evaporation of defrost water within the drip tray and effectively preventing the risk of defrost water overflow due to slow evaporation. Simultaneously, this arrangement requires no additional energy consumption, relying solely on the heating characteristics of the compressor 100 itself to achieve efficient evaporation, enhancing the overall structural reliability and practicality. In addition, the relative positional relationship between the first drip tray 300 and the compressor 100 also provides opportunities for optimizing the internal space layout of the refrigerator, resulting in a more compact and functionally complete overall structure.

[0033] Correspondingly, the second drip tray 400 can be implemented using a disc-shaped structure with a certain depth and volume. In practical applications, by positioning the second drip tray 400 at the bottom of the refrigerator, it can effectively utilize gravity to allow defrost water to naturally collect at the lowest point, thereby avoiding accumulation in the middle path. The purpose of this design is to optimize the flow path of defrost water and improve the evaporation efficiency of defrost water by utilizing the heating effect of the evaporator tube assembly 200.

[0034] In a further embodiment, such as Figure 2 As shown, the defrost water receiving structure also includes a connecting pipe 500. The first water receiving tray 300 is connected to the second water receiving tray 400 through the connecting pipe 500, so that the defrost water in the first water receiving tray 300 can overflow to the second water receiving tray 400 through the connecting pipe 500. Specifically, the connecting pipe 500 is a component used to establish a water flow channel between the first water receiving tray 300 and the second water receiving tray 400. It can be made of plastic, metal, or other materials with appropriate rigidity and corrosion resistance. The connecting pipe 500 can be implemented by fixing both ends to the first water receiving tray 300 and the second water receiving tray 400 respectively, for example, by plugging, threading, or bonding. The purpose is to ensure that the defrost water can flow smoothly between the two water receiving trays, while avoiding loosening of the connection due to external vibration or temperature changes.

[0035] Specifically, this solution effectively solves the problem of defrost water transfer between the high-level first drip tray 300 and the low-level second drip tray 400 by introducing a connecting pipe 500 as a key connecting component. Given the height difference between the first drip tray 300 and the second drip tray 400, the connecting pipe 500 allows defrost water accumulated in the first drip tray 300 to naturally overflow to the second drip tray 400 by gravity when it reaches a specific water level, thus avoiding the risk of overflow due to insufficient capacity of a single drip tray. Of course, in other embodiments, the water can also flow directly into the second drip tray 400 through the through hole 320 at the bottom of the first drip tray 300. The connecting pipe 500, as a physical channel, is fixedly connected at both ends to the first drip tray 300 and the second drip tray 400, forming a continuous water flow path. This connection method fully utilizes the spatial layout characteristics inside the refrigerator, namely the potential energy difference between the high-level first drip tray 300 and the low-level second drip tray 400, enabling automatic transfer of defrost water without external power. As the defrost water in the first drip tray 300 gradually increases and approaches full capacity, the water flows smoothly into the second drip tray 400 through the connecting pipe 500. This not only expands the overall capacity but also ensures the dynamic balance of defrost water within the structure, significantly improving the reliability and stability of defrost water management. Furthermore, the design of the connecting pipe 500, combined with the height difference between the first and second drip trays 300, further optimizes the flow efficiency of the defrost water, demonstrating the overall ingenuity of the technical solution.

[0036] In a further embodiment, such as Figure 3 and Figure 4 As shown, the defrosting water containing structure also includes an overflow pipe 600. The first water receiving tray 300 is provided with a first receiving groove 310. One end of the overflow pipe 600 is connected to the bottom wall of the first receiving groove 310, and the other end extends toward the opening of the first receiving groove 310. The overflow pipe 600 is provided with an overflow hole 610, and the maximum height of the overflow hole 610 is lower than the minimum height of the opening of the first receiving groove 310. The bottom wall of the first receiving groove 310 is provided with a through hole 320, and a connecting pipe 500 is connected to the bottom of the through hole 320. The first receiving groove 310, the overflow hole 610, the through hole 320, and the connecting pipe 500 are connected in sequence.

[0037] Specifically, the overflow pipe 600 refers to a pipe structure used to control the flow of defrost water, which can be implemented using a straight pipe, a bend, or other tubular structure with flow guiding function. In practical applications, the overflow pipe 600, by being set at a specific position within the first receiving tank 310, ensures that defrost water only begins to overflow after reaching a certain height, thereby preventing premature loss. It should be noted that the overflow hole 610 refers to an opening provided on the overflow pipe 600, which can be circular, elliptical, or rectangular, etc., for the purpose of precisely controlling the timing of defrost water overflow. The through hole 320 refers to a through hole formed on the bottom wall of the first receiving tank 310, which can be round, square, or other types of opening designs to achieve a reliable connection with the connecting pipe 500. Furthermore, through the above technical solution, not only is the problem of premature overflow of defrost water solved, but it also ensures that the defrost water in the first water receiving tray 300 has sufficient time to evaporate using the heat of the compressor 100, thereby optimizing the overall performance of defrost water treatment.

[0038] In a further embodiment, the sidewall of the overflow pipe 600 is provided with a first side opening 620 connecting the overflow hole 610 and the first receiving groove 310. The number of first side openings 620 is multiple and they are arranged at intervals along the circumference of the overflow pipe 600. Specifically, the first side opening 620 refers to an auxiliary channel structure provided on the sidewall of the overflow pipe 600 for connecting the overflow hole 610 and the first receiving groove 310. It can be implemented using different shapes of openings such as circular, elliptical, or rectangular, with the purpose of providing additional water flow paths to cope with the situation where the overflow hole 610 is blocked. It should be noted that the design of multiple first side openings 620 evenly distributed along the circumference of the overflow pipe 600 ensures that water flows into the overflow pipe 600 from different directions, thereby avoiding local blockages from affecting the overall overflow effect.

[0039] Specifically, this technical solution effectively solves the problem of defrosting water not overflowing in a timely manner due to the potential blockage of the overflow hole 610 by impurities by adding multiple circumferentially distributed first side openings 620 to the side wall of the overflow pipe 600. When the overflow hole 610 is blocked by impurities, defrosting water can bypass the blockage point and flow directly into the overflow pipe 600 through the side openings, preventing the water level from rising continuously and causing the first water receiving tray 300 to overflow. The multiple first side openings 620 not only improve the redundancy and reliability of the overflow path, but also make full use of the three-dimensional spatial structure of the overflow pipe 600, allowing defrosting water to enter the overflow pipe 600 efficiently from different directions. In addition, this design, together with the first receiving tank 310 and the through hole 320, forms a complete overflow system, ensuring the smooth discharge of defrosting water even under complex operating conditions, thereby significantly improving the stability and reliability of the entire defrosting water receiving structure.

[0040] In a further embodiment, the opening of the overflow hole 610 faces away from the bottom wall of the first receiving groove 310, and the end of the first side opening 620 near the opening of the overflow hole 610 penetrates the side wall of the overflow pipe 600, so that the first side opening 620 forms a notch structure on the side wall of the overflow pipe 600. Specifically, the overflow hole 610 refers to a through hole provided on the overflow pipe 600 for guiding the flow of defrosting water, which can be circular, elliptical, or other suitable shapes. The purpose of this design is to optimize the water flow direction and avoid splashing and eddy currents caused by water impacting the bottom wall. The first side opening 620 is a specific structure on the side wall of the overflow pipe 600, which can be formed by cutting, stamping, etc., and the size and shape of the opening can be adjusted according to actual needs.

[0041] In a further embodiment, the connecting pipe 500 is fixedly inserted into the through hole 320. Specifically, the fixed insertion of the connecting pipe 500 means that the connecting pipe 500 is securely installed in the through hole 320 through an interference fit, snap-fit, or other mechanical connection method, thereby avoiding loosening or detachment due to vibration or thermal expansion and contraction. The purpose of this design is to ensure a tight connection between the connecting pipe 500 and the through hole 320, preventing defrost water leakage during flow. Specifically, the design of fixing the connecting pipe 500 into the through hole 320 effectively constrains the axial and radial displacement of the connecting pipe 500 during refrigerator operation by strengthening the physical connection between the connecting pipe 500 and the bottom wall of the first drip tray 300. This tight mechanical fit not only eliminates any possible small gaps at the connection point but also avoids the problem of gap widening or accidental detachment that may occur with a simple insertion method. Furthermore, the fixed insertion method of the connecting pipe 500 and the through hole 320 can adapt to the continuous vibration and temperature fluctuation environment generated when the refrigerator compressor 100 is working, thereby ensuring the continuity and reliability of the defrosting water transfer process from the first drip tray 300 to the second drip tray 400. This design not only ensures the sealed flow of defrosting water but also improves the overall leak-proof performance of the structure.

[0042] In a further embodiment, such as Figure 5 and Figure 6As shown, the defrost water receiving structure also includes a clamp 700. The second water receiving tray 400 is provided with a second receiving groove 410. One end of the clamp 700 is fixedly connected to the inner wall of the second receiving groove 410, and the other end is engaged with the connecting pipe 500. The connecting pipe 500 can connect to the second receiving groove 410 through the clamp 700. Specifically, the clamp 700 is an intermediate component used to achieve a stable connection between the connecting pipe 500 and the second water receiving tray 400. It can be made of elastic plastic or metal, utilizing material elasticity or geometry to achieve quick installation and tight locking. The second receiving groove 410 is a recessed area provided on the second water receiving tray 400, used to receive defrost water and provide installation space for the clamp 700. In practical applications, one end of the clamp 700 can be fixed to the inner wall of the second receiving groove 410 by means of threaded connection, welding or integral molding to ensure that it forms a rigid connection with the second water receiving tray 400; the other end is connected to the connecting pipe 500 by means of a snap-fit ​​structure or interference fit to ensure the sealing and stability of the connection.

[0043] Specifically, this solution effectively solves the problem of unstable connection between the connecting pipe 500 and the second drip tray 400 through the design of the clamp 700. One end of the clamp 700 is fixedly connected to the inner wall of the second receiving groove 410. This fixing method avoids displacement caused by vibration during refrigerator operation and provides a reliable support foundation for subsequent connections. The other end engages with the connecting pipe 500, utilizing material elasticity or geometry to achieve quick installation and tight locking, ensuring that the connecting pipe 500 is not easily slipped off under force. At the same time, the connecting pipe 500 connects to the second receiving groove 410 through the clamp 700, optimizing the water flow path and confining the defrosting water within the predetermined channel during overflow, preventing water leakage due to gaps caused by loose connections. In addition, since the height of the first drip tray 300 is greater than that of the second drip tray 400, the defrosting water can flow naturally by gravity, further improving the stability and reliability of the system. The above technical solution not only achieves a stable connection between the connecting pipe 500 and the second water receiving tray 400, but also ensures the overall sealing and long-term operational stability of the defrosting water containment system.

[0044] In a further embodiment, the defrosting water receiving structure also includes a baffle pipe 800, which has a baffle hole 810. The baffle pipe 800 is connected to the inner wall of the second receiving groove 410 and covers the outer periphery of the clamp 700 through the baffle hole 810, so that the connecting pipe 500 can connect to the second receiving groove 410 through the baffle hole 810. Specifically, the baffle pipe 800 is a structural component used to guide and restrict the water flow path, which can be implemented using a cylindrical, square, or other adaptable pipe shape. The design of the baffle hole 810 is based on the outer periphery contour of the clamp 700, which can accurately match the shape of the clamp 700, thereby forming a restricted water flow channel and avoiding turbulence caused by sudden changes in water velocity. The baffle pipe 800 is connected to the inner wall of the second receiving groove 410. This fixing method utilizes the structural stability of the second receiving groove 410 to prevent the baffle pipe 800 from shifting under long-term water flow impact, ensuring the reliability of the overall device. In addition, the baffle 810 is installed on the outer periphery of the clamp 700. This arrangement forms a physical barrier around the clamp 700, guiding the water flow to transition smoothly along the inner wall of the baffle 800, rather than being directly exposed to the air, significantly reducing the risk of splashing.

[0045] In a further embodiment, the sidewall of the baffle pipe 800 is provided with a second side opening 820 connecting the baffle hole 810 and the second receiving groove 410. The number of second side openings 820 is multiple and they are arranged at intervals along the circumference of the baffle pipe 800. Specifically, the baffle pipe 800 refers to a pipe structure used to guide the flow of defrost water and prevent water overflow. It can be made of materials with certain strength and corrosion resistance, such as metal or plastic. The second side opening 820 refers to a through-hole structure provided on the sidewall of the baffle pipe 800, which can be formed by stamping, drilling, or other methods to provide additional water flow channels to disperse water pressure. The second receiving groove 410 refers to a receiving space for receiving defrost water flowing in from the baffle pipe 800, which can be formed by injection molding or machining.

[0046] Specifically, multiple second side openings 820 are provided on the side wall of the baffle pipe 800. These openings are evenly distributed along the circumference of the baffle pipe 800, allowing defrosting water to flow into the second receiving tank 410 through multiple paths. This design fully utilizes the geometry of the baffle pipe 800, transforming the originally closed side wall into a multi-path water flow channel. This not only significantly reduces water flow resistance but also ensures that the water flow is evenly distributed around the pipe. In this way, the flow velocity bottleneck problem caused by a single channel is effectively avoided, while preventing blockage or stagnation in local areas due to concentrated water flow, thereby improving the overall stability and distribution efficiency of the water flow.

[0047] In a further embodiment, the clamp 700 includes a first clamping plate 710 and a second clamping plate 720. The first clamping plate 710 and the second clamping plate 720 are cross-shaped and fixedly connected to form a cross-shaped or X-shaped clamp 700. The connecting pipe 500 connects to the flow-blocking hole 810 through the gap between the first clamping plate 710 and the second clamping plate 720. Specifically, the clamp 700 refers to a structural component for fixing the connecting pipe 500, which can be made by stamping or injection molding of metal sheet. The cross-shaped arrangement of the first clamping plate 710 and the second clamping plate 720 can provide a symmetrical support frame, thereby effectively dispersing external forces and avoiding stress concentration. The purpose of this design is to enhance the overall rigidity and deformation resistance of the clamp 700, ensuring that the connecting pipe 500 remains stable under vibration.

[0048] In practical applications, the spacing between the first clamping plate 710 and the second clamping plate 720 is precisely matched to the outer diameter of the connecting pipe 500. This design ensures both the stable embedding of the connecting pipe 500 and maintains a smooth flow path for defrosting water. The cross-shaped or X-shaped design utilizes geometric symmetry to provide balanced support for the connecting pipe 500 in multiple directions during refrigerator operation, preventing loosening or displacement caused by localized forces.

[0049] Specifically, this technical solution forms a self-locking snap-fit ​​structure through the cross-fixed connection of the first snap-fit ​​plate 710 and the second snap-fit ​​plate 720. After the connecting pipe 500 is embedded in the gap between the first snap-fit ​​plate 710 and the second snap-fit ​​plate 720, it can obtain balanced support in multiple directions, effectively preventing accidental detachment of the connecting pipe 500 even when the baffle pipe 800 is covered on the outer periphery of the snap-fit ​​head 700. This structural design not only enhances the reliability of the fit between the connecting pipe 500 and the snap-fit ​​head 700, but also ensures that the defrosting water system maintains high efficiency and stability during long-term operation.

[0050] In a further embodiment, the first clamping plate 710 and the second clamping plate 720 are provided with a locking slot 730 on their periphery, through which the connecting pipe 500 is secured to the clamping head 700. Specifically, the locking slot 730 refers to a precise locking position designed on the edge of the first clamping plate 710 and the second clamping plate 720, which can be implemented using a groove, a protrusion, or other geometrically shaped structure. The purpose of the locking slot 730 is to utilize the rigid structure of the clamping plate itself to form a stable constraint point, thereby preventing the connecting pipe 500 from shaking due to uneven gaps after installation. The feature of the connecting pipe 500 being secured to the clamping head 700 through the locking slot 730 can be achieved by the elastic deformation or geometric shape of the locking slot 730 cooperating with the connecting pipe 500, ensuring that the connecting pipe 500 receives a uniform clamping force after being engaged, and is not easily dislodged due to thermal expansion and contraction or external vibration.

[0051] In summary, the above technical solutions have successfully solved the problems of loosening of the connecting pipe 500 and defrost water leakage caused by vibration or thermal expansion and contraction during refrigerator operation, significantly improving the reliability and practicality of the defrost water containment structure.

[0052] In a further embodiment, the evaporator tube assembly 200 is at least partially disposed within the second drip tray 400. Specifically, the evaporator tube assembly 200 refers to a pipe component used in the refrigeration system to achieve heat exchange, and it can be implemented using a spiral, U-shaped, or other adaptable pipe structure made of metal. In practical applications, the second drip tray 400 refers to a container structure used to contain defrost water and utilize heat to accelerate evaporation. It can be a trough-shaped or box-shaped structure with appropriate depth and volume, aiming to provide sufficient space to contain defrost water and optimize heat transfer efficiency. "At least partially disposed" means that part or all of the evaporator tube assembly 200 is arranged inside the second drip tray 400, the purpose of which is to adapt to the needs of different refrigerator structures through flexible design, while ensuring that heat can be efficiently transferred to the defrost water.

[0053] In a further embodiment, the first water receiving tray 300 is provided with a first receiving groove 310, and the bottom wall of the first water receiving tray 300 is recessed towards the first receiving groove 310, so that the side of the first water receiving tray 300 facing the compressor 100 forms a concave structure 330 for adapting to the shape of the compressor 100. Specifically, the first receiving groove 310 refers to the basic structure for storing defrost water, which can be implemented by a groove design with appropriate depth and shape, the purpose of which is to provide a stable receiving space for defrost water. The concave setting of the bottom wall means that the bottom wall of the first water receiving tray 300 is not a simple flat design, but is specifically adjusted according to the actual shape characteristics of the compressor 100, thereby forming a structure that fits tightly against the surface of the compressor 100. The purpose of this design is to improve heat conduction efficiency and accelerate the evaporation process of defrost water by reducing air gaps and reducing thermal resistance.

[0054] This application also discloses a refrigerator, which includes a compressor 100, an evaporator tube assembly 200, and a defrost water containing structure as described in any of the above embodiments. A first drip tray 300 is installed on one side of the compressor 100, and a second drip tray 400 is disposed on one side of the evaporator tube assembly 200. The concept of this application is that by combining the first drip tray 300 and the second drip tray 400 in the form of a dual-tray system, and utilizing the heat naturally generated during the operation of the compressor 100 and the evaporator tube assembly 200 respectively, the problem of defrost water easily overflowing the drip tray in pure freezers or refrigerators with large cooling capacity is effectively solved, thereby improving the defrost water treatment efficiency and reducing the risk of leakage.

[0055] Specifically, this technical solution integrates a dual drip tray system with the core components of the refrigerator, fully utilizing the naturally generated heat resources during refrigerator operation and avoiding additional energy consumption. Based on the continuous heat generation characteristic of the compressor 100, the first drip tray 300 is installed on one side of the compressor 100, allowing defrost water to directly absorb the waste heat of the compressor 100 and evaporate quickly. This arrangement fully utilizes the heat transfer efficiency of the compressor 100, significantly shortening the residence time of defrost water in the drip tray, thereby preventing water accumulation due to insufficient heat. Simultaneously, based on the heat release characteristic of the evaporator coil assembly 200 during the defrosting stage, the second drip tray 400 is positioned on one side of the evaporator coil assembly 200, allowing defrost water to instantly capture the heat from the evaporator coil assembly 200 for evaporation. This configuration avoids the space occupied by the evaporator in traditional single drip trays, and is particularly suitable for pure freezer refrigerators with large evaporator sizes. The dual-disc design of the defrost water receiving structure distributes the tasks of defrost water collection and evaporation. Through the coordinated operation of the first and second drip trays 300, the overall evaporation area is expanded, heat utilization efficiency is improved, and the risk of defrost water leakage is fundamentally reduced. Furthermore, this structure allows the evaporator tube assembly 200 to be partially embedded in the second drip tray 400, optimizing the space layout and maximizing defrost water handling capacity within the limited refrigerator volume, ensuring stable system operation even under high cooling capacity.

[0056] The defrosting water container structure can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the defrosting water container structure to perform corresponding operations, thereby realizing intelligent control of the defrosting water container structure and improving the user experience.

[0057] The smart appliance equipped with the defrosting water containment structure has a smart voice control module. The smart voice control module includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the defrosting water containment structure to perform corresponding operations, thereby realizing the intelligent control of the defrosting water containment structure and improving the user experience of using the smart appliance.
