Abstract
Description
Technical Field
[0001] This application relates to the field of defrosting and heat dissipation technology for refrigerators, and in particular to an embedded refrigerator. Background Technology
[0002] Built-in refrigerators need to be installed inside cabinets or walls, so air inlets / outlets are required through the exposed side of the cabinet or wall (usually called the front side). Therefore, when designing the internal structure, it is necessary to consider how to arrange the airflow circulation path to achieve a "front air inlet, front air outlet" gas circulation scheme.
[0003] In existing technology, at the bottom of a built-in refrigerator, airflow enters through the air inlet, passes sequentially through the drip tray, condenser, and compressor, and then exits from the front side of the refrigerator. In this arrangement, the condenser is typically mounted on the drip tray and positioned away from the air inlet, with a deflector on the side of the drip tray closest to the air inlet to guide the airflow from the inlet to the condenser. However, for smaller refrigerators, the bottom dimensions also decrease, leading not only to a reduced drip tray volume, which hinders rapid evaporation of defrost water, but also to a smaller air intake space for the condenser, resulting in insufficient airflow at the condenser and poor heat dissipation. Utility Model Content
[0004] Therefore, it is necessary to provide an embedded refrigerator that can improve the efficiency of defrosting water evaporation and the heat dissipation effect of the condensing mechanism.
[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0006] An embedded refrigerator includes a cabinet, a drip tray, a drain pipe, a condensing mechanism, and an air guiding mechanism. Along the depth direction of the refrigerator, one side of the cabinet has an air inlet and an air outlet. The drip tray is located at the bottom of the cabinet, and the drain pipe is installed on the drip tray to collect defrost water generated by the evaporator and guide the defrost water to the drip tray. The condensing mechanism is installed at the bottom of the drip tray and has an air inlet surface. The air guiding mechanism is integrated with the drip tray and located between the air inlet and the condensing mechanism to guide air from the air inlet to the air inlet surface. The air inlet surface faces the air inlet along the depth direction of the embedded refrigerator, and along the depth direction from the air inlet to the condensing mechanism, the air inlet surface forms an acute angle with the depth direction of the embedded refrigerator.
[0007] Understandably, this application integrates the air guide mechanism and the water collection tray into a single structure, thereby expanding the space of the water collection tray and increasing the evaporation surface area of the defrost water, which is more conducive to evaporation. At the same time, by setting the air inlet surface at an acute angle to the depth direction of the built-in refrigerator, the condenser mechanism can cover more air inlets. This allows the air at the air inlets to be drawn into the condenser mechanism, improving airflow and enhancing the ventilation and heat dissipation efficiency of the condenser mechanism.
[0008] In one embodiment, the angle between the air intake surface and the depth direction of the embedded refrigerator is A, where 30°≤A≤60°.
[0009] In one embodiment, the air guiding mechanism includes an air guiding plate located on the side of the water receiving tray closer to the air inlet in the depth direction of the embedded refrigerator;
[0010] Furthermore, in the depth direction of the embedded refrigerator and from the air inlet to the condensation mechanism, the air guide plate gradually rises in the height direction of the embedded refrigerator.
[0011] Understandably, by setting up a guide vane whose height gradually increases along the depth direction, the airflow can be guided to rise upwards along the guide vane after entering from the air inlet, preventing airflow turbulence caused by the airflow blowing directly onto the side wall of the water receiving tray, thereby improving airflow efficiency and enhancing the evaporation efficiency of defrosting water.
[0012] In one embodiment, the air guide mechanism further includes a reinforcing plate, which is connected to the air guide plate and the water receiving tray respectively.
[0013] In one embodiment, the number of air guide plates is set to multiple pieces, and the multiple air guide plates are spaced apart along the width direction of the embedded refrigerator, forming an air duct between two adjacent air guide plates.
[0014] In one embodiment, the air guiding mechanism further includes an air guiding groove, which is disposed on the bottom of the water receiving tray and extends along the depth direction of the embedded refrigerator, and is at least partially located between the condensation mechanism and the air inlet.
[0015] Understandably, by setting up air guide grooves, the airflow entering through the air inlet can be further guided to the air intake surface, thereby improving airflow circulation efficiency and enhancing the heat dissipation effect of the built-in refrigerator. Furthermore, by placing the air guide grooves at the bottom of the drip tray, localized stress can be dispersed, extending the lifespan of the drip tray.
[0016] In one embodiment, the condensation mechanism includes a base, a chassis, a condenser, and a fan. The base is installed on the bottom of the drip tray and is inclined relative to the depth direction of the embedded refrigerator. The chassis is installed on the base and has the air inlet surface. The condenser and the fan are both installed inside the chassis.
[0017] In one embodiment, the condensation mechanism further includes a pipe connected to the condenser and disposed within a drip tray.
[0018] In one embodiment, along the depth direction of the deformation, the water receiving tray has an avoidance notch on the side away from the air outlet.
[0019] In one embodiment, the cabinet is provided with a freezing chamber and a refrigeration chamber, and the drain pipe includes a first pipe and a second pipe. One end of the first pipe is connected to the freezing chamber and the other end is connected to the water collection tray. One end of the second pipe is connected to the refrigeration chamber and the other end is connected to the water collection tray.
[0020] Compared with existing technologies, the embedded refrigerator integrates the air guide mechanism and the water tray into a single structure, thereby expanding the space of the water tray and increasing the evaporation surface area of the defrost water, which is more conducive to evaporation. At the same time, the air inlet is set at an acute angle to the depth direction of the embedded refrigerator, so that the condensing mechanism can cover more air inlets. This allows the air at the air inlets to be drawn into the condensing mechanism, improving air flow and enhancing the ventilation and heat dissipation efficiency of the condensing mechanism.

[0035] Built-in refrigerators are primarily embedded into cabinets or walls, seamlessly integrating with the space. Typically, only one side of the refrigerator (the side with the door) is exposed, allowing users easy access to items. Due to this design, the air intake and exhaust are usually located on the side with the door; this type of air intake and exhaust is commonly referred to as "front intake, front exhaust."
[0036] Built-in refrigerators have components such as a drip tray, air guide, condenser, and compressor at their bottom. The drip tray connects to the drain pipes of the refrigerator and freezer compartments to collect defrost water flowing from the drain pipes. The condenser and compressor are the main components of the refrigerator's refrigeration system. The condenser is mounted on the drip tray, and air from the air inlet passes over the drip tray before entering the condenser, accelerating the evaporation of defrost water and the removal of moisture. The air guide directs the airflow from the air inlet to the condenser. However, for small-sized built-in refrigerators, the limited area at the bottom, coupled with the space occupied by the compressor and condenser (which generally cannot be reduced), necessitates a corresponding reduction in the size of the drip tray. This reduced volume hinders effective defrost water collection; the reduced evaporation area impedes rapid defrost water evaporation; and the reduced bottom width decreases the heat dissipation area and reduces the space for the condenser's air intake, further hindering ventilation and heat dissipation at the bottom of the refrigerator. Therefore, this application proposes the following technical solution to address the aforementioned problems.
[0037] Specifically, please refer to Figures 1 to 6This application provides an embedded refrigerator 100, which includes a cabinet 10, a drip tray 20, a drain pipe 30, a condensing mechanism 40, and an air guide mechanism 50. In the depth direction y of the embedded refrigerator 100, one side of the cabinet 10 has an air inlet 11 and an air outlet 12. The drip tray 20 is located at the bottom of the cabinet 10. The drain pipe 30 is installed on the drip tray 20 to collect defrost water generated by the evaporator (not shown) and guide the defrost water to the drip tray 20. The condensing mechanism 40 is installed on the drip tray 20. The bottom of the refrigerator 100 has an air inlet surface 41. The air guide mechanism 50 and the water receiving tray 20 are integrated and located between the air inlet 11 and the condensing mechanism 40. The air guide mechanism 50 is used to guide the air at the air inlet 11 to the air inlet surface 41. The air inlet surface 41 is set towards the air inlet 11 in the depth direction y of the built-in refrigerator 100. Along the depth direction y of the built-in refrigerator 100 and from the air inlet 11 to the condensing mechanism 40, the air inlet surface 41 and the depth direction y of the built-in refrigerator 100 are set at an acute angle. It is understandable that the built-in refrigerator 100 provided in this application integrates the air guide mechanism 50 and the water tray 20 into one structure, that is, integrates the air guide mechanism 50 and the water tray 20 together, thereby expanding the space of the water tray 20 and increasing the evaporation surface area of the defrost water, which is more conducive to evaporation. At the same time, the air inlet surface 41 is set at an acute angle to the depth direction y of the built-in refrigerator 100, so that the condensing mechanism 40 can cover more air inlets 11. In this way, the air at the air inlets 11 can be basically drawn into the condensing mechanism 40 and improve the air flow, thereby improving the ventilation and heat dissipation efficiency of the condensing mechanism 40.
[0038] In one embodiment, the water receiving tray 20 and the air guiding mechanism 50 can be integrally formed by injection molding or casting. In this embodiment, the water receiving tray 20 and the air guiding mechanism 50 are integrally injection molded.
[0039] like Figure 1 As shown, the drain pipe 30 includes a first pipe 31 and a second pipe 32. The cabinet 10 has a freezer chamber (not shown) and a refrigerator chamber (not shown). One end of the first pipe 31 is installed on the cabinet 10 and connects to the freezer chamber, while the other end is connected to the drip tray 20. One end of the second pipe 32 is installed on the cabinet 10 and connects to the refrigerator chamber, while the other end is connected to the drip tray 20. Thus, defrosting water from the freezer chamber and the refrigerator chamber can be introduced into the drip tray 20 through the first pipe 31 and the second pipe 32, respectively.
[0040] like Figure 4As shown, the angle between the air inlet surface 41 and the depth direction y of the embedded refrigerator 100 is A, where 30°≤A≤60°. Here, by tilting the condensing mechanism 40, the projection of the air inlet surface 41 along the depth direction y of the embedded refrigerator 100 toward the air guide mechanism 50 is located within the area of the air inlet 11. The airflow within the projection can flow directly to the air inlet surface 41, thereby improving the air intake efficiency of the condensing mechanism 40. By setting 30°≤A≤60°, the airflow from the air inlet 11 to the air inlet surface 41 can be effectively guaranteed without affecting the airflow from the rear of the condensing mechanism 40.
[0041] Optionally, the included angle A can be 30°, 45°, 50°, 60°, etc. Of course, the specific value of the included angle A can be set according to the actual situation.
[0042] In this embodiment, the included angle A = 45°. When A = 45°, the air volume flowing from the air inlet 11 to the air inlet surface 41 is relatively large, and at the same time, the airflow can flow smoothly out from the rear side of the condensation mechanism 40.
[0043] like Figures 2 to 4 As shown, the condensing mechanism 40 includes a base 42, a casing 43, a condenser 44, and a fan 45. The base 42 is installed on the bottom of the drip tray 20 and is inclined relative to the depth direction y of the built-in refrigerator 100. The casing 43 is installed on the base 42 and has an air inlet surface 41. The condenser 44 and the fan 45 are both installed inside the casing 43. During the air intake process, the fan 45 rotates to create a negative pressure, thereby drawing the air entering through the air inlet 11 to the condenser 44 for heat exchange.
[0044] In one embodiment, the base 42 can be fixed to the bottom of the water receiving tray 20 by welding or threaded connection. The side of the chassis 43 facing the air inlet 11 has multiple mesh holes, thus forming an air inlet surface 41. Of course, the side of the chassis 43 away from the air inlet 11 is the air outlet (not shown in the figure). Air enters the chassis 43 through the air inlet surface 41, exchanges heat with the condenser 44, and is discharged from the air outlet. After passing through other components, it is discharged from the air outlet 12, thus forming a cycle.
[0045] Here, the condenser 44 can be configured as any one of a wire tube condenser, a finned coil condenser, a microchannel condenser, etc.
[0046] In this embodiment, the condenser 44 is configured as a microchannel condenser.
[0047] Furthermore, such as Figure 2 and Figure 3As shown, the condensing mechanism 40 also includes a pipe 46, which is connected to the condenser 44 and arranged within the drip tray 20. Here, by arranging the pipe 46 within the drip tray 20, the refrigerant inside the pipe 46 can exchange heat with the defrosting water. On the one hand, the low temperature environment of the defrosting water is used to cool the refrigerant, and on the other hand, the refrigerant is used to heat the defrosting water, thereby accelerating the evaporation efficiency of the defrosting water.
[0048] Preferably, the pipe 46 is laid flat inside the water receiving pan 20, so that the pipe 46 can fill the water receiving pan 20, thereby improving the evaporation of defrost water and the cooling of the refrigerant inside the pipe 46.
[0049] like Figures 1 to 5 As shown, the air guiding mechanism 50 includes an air guide plate 51, which is located on the side of the drip tray 20 in the depth direction y of the built-in refrigerator 100, close to the air inlet 11. Furthermore, in the depth direction y of the built-in refrigerator 100 and from the air inlet 11 to the condenser mechanism 40, the air guide plate 51 gradually rises in the height direction z of the built-in refrigerator 100. Thus, by setting the air guide plate 51, whose height gradually increases along the depth direction y, the airflow can be guided to rise upwards along the air guide plate 51 after entering from the air inlet 11, preventing airflow turbulence caused by the airflow directly blowing onto the side wall of the drip tray 20, thereby improving airflow efficiency and enhancing the evaporation efficiency of defrost water.
[0050] In one embodiment, such as Figure 2 and Figure 3 As shown, multiple air guide plates 51 are arranged at intervals along the width x direction of the embedded refrigerator 100, forming an air duct 511 between adjacent air guide plates 51. When the air at the air inlet 11 passes through the multiple air guide plates 51, it is lifted under the guidance of the air guide plates 51 and flows towards the condenser mechanism 40. At the same time, the air guide plates 51 here can also serve as reinforcing ribs to strengthen the structural strength of the water receiving tray 20 at this location.
[0051] In another embodiment, such as Figure 5 and Figure 6 As shown, the air guide plate 51 is configured as an inclined plate-like structure, and the air guiding mechanism 50 also includes a reinforcing plate 52, which connects the air guide plate 51 and the water receiving tray 20 respectively. Here, the part used for air guiding is the side of the plate-like structure facing the air inlet 11. Furthermore, by providing the reinforcing plate 52, the stability of the air guide plate 51 and the water receiving tray 20 can be enhanced.
[0052] like Figures 1 to 5As shown, in each embodiment, the air guiding mechanism 50 further includes an air guiding groove 53. The air guiding groove 53 is disposed on the bottom of the water receiving tray 20 and extends along the depth direction y of the embedded refrigerator 100, and is at least partially located between the condensing mechanism 40 and the air inlet 11. Here, by providing the air guiding groove 53, the airflow entering from the air inlet 11 can be guided to the air inlet surface 41, thereby improving the airflow circulation efficiency and enhancing the heat dissipation effect of the embedded refrigerator 100. In addition, by providing the air guiding groove 53 on the bottom of the water receiving tray 20, the air guiding groove 53 can disperse local stress, avoiding structural problems in areas such as the drain outlet edge and assembly points due to long-term high pressure, and extending the life of the water receiving tray 20.
[0053] Preferably, the air guide grooves 53 can be formed directly on the water receiving tray 20 during injection molding. Multiple air guide grooves 53 can be provided, spaced apart along the width x-direction of the refrigerator and covering the bottom of the water receiving tray 20, thus structurally reinforcing the water receiving tray 20 as a whole.
[0054] like Figure 1 As shown, the built-in refrigerator 100 also has a compressor 60 inside. Along the depth direction y of the refrigerator, the drip tray 20 has a clearance notch 21 on the side away from the air outlet 12. The compressor 60 is installed at the clearance notch 21.
[0055] The working principle and process of the built-in refrigerator 100 are explained in detail below:
[0056] Air enters through the air inlet 11, and under the guidance of the air guide plate 51 and the air guide groove 53, it passes through the air inlet surface 41 and enters the casing 43, where it exchanges heat with the condenser 44. After heat exchange, the air flows out through the air outlet surface of the casing 43, then through the compressor 60, and finally flows out from the air outlet 12.
[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
