[0037] In order to make the technical problem, technical scheme and beneficial effect to be solved in the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples.It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0038] At present, the fin evaporator lower part of the air-cooled refrigerator is generally equipped with a defrosting heater, and the surface temperature of the defrosting heater needs to meet the safety requirements. After the evaporator is assembled into the box liner, an aluminum defrosting water pan is assembled at the lower part of the heater. The current defrosting water pan is basically manually attached in the groove of the box liner. The disadvantages of this method are as follows: the consistency of manual attachment is difficult to guarantee, and in addition, the corner needs to be supplemented by the production line workers with aluminum foil. At the same time, the air-cooled refrigerator needs to design the air ducts of the air inlet and the air return, and for this reason, the corresponding hole positions are mostly increased on the box liner by punching, which is not suitable for some small capacity (such as capacity ≤ 250 liters) air-cooled refrigerators.

[0039] Therefore, the utility model provides a water pan and air duct integrated structure and a refrigerator, which are integrally assembled into the lower part of the evaporator of the box liner through the integrated design of the water pan and the air duct, and the overall assembly quality is improved.

[0040] As shown in Figure 1 , Figure 2 , Figure 3 The utility model provides a water pan and air duct integrated structure 1 which comprises:

[0041] The water pan and air duct integrated structure 1 comprises:

[0042] The air duct component 12 comprises a containing groove body 120 for containing the water pan groove body 110 and an air inlet air duct 121 and an air return air duct arranged on the containing groove body 120, and the containing groove body 120 is provided with a water discharge mounting port 1201 for the water discharge pipe 112 at the position corresponding to the water discharge port 111.

[0043] The advantages of this design are that the water pan and air duct integrated structure 1 is an integral forming piece, which contains both the water pan component 11 and the air duct component 12, the multifunctional requirements are realized on the same part, the overall assembly to the inside of the refrigerator is facilitated, and the overall assembly quality is improved.

[0044] Preferably, the water pan component 11 is made of aluminum product, and the water pan component 11 and the air duct component 12 are integrally pressed and formed, so as to ensure that the water pan component 11 is closely attached to the air duct component 12, and the water pan component 11 is fully covered in the containing groove body 120 of the air duct component 12, which is beneficial to defrosting heat dissipation and deformation resistance, and the production line workers do not need to use aluminum foil to make up for the missing places of the water pan attachment.

[0045] For better understanding, the structure of the air duct component 12 will be described in more detail.

[0046] As shown in Figure 2As shown in the drawings, in the air duct component 12, the air inlet duct 121 and the air return duct are arranged on opposite sides of the accommodating groove body 120, and the air inlet port 1210 of the air inlet duct 121 and the air return port 1220 of the air return duct are arranged in a staggered manner.

[0047] It should be noted that the port of the air inlet duct 121 close to one end of the accommodating groove body 120 is called the air inlet port 1210, and the port of the air return duct close to one end of the accommodating groove body 120 is called the air return port 1220.

[0048] The advantage of this design is that the arrangement between the air inlet duct 121 and the air return duct avoids the air return short circuit phenomenon. At the same time, it can meet the assembly of the upper frozen and lower stored product, and also meet the assembly of the upper stored and lower frozen product.

[0049] As shown in the drawings, Figure 2 As shown in the drawings, in the air duct component 12, the air direction of the air inlet port 1210 is perpendicular to the air direction of the air return port 1220.

[0050] It should be noted that, as shown in the drawings, Figure 11 After the water pan and the air duct integrated structure 1 are assembled into the refrigerator, the air direction of the air inlet port 1210 is upward and downward (as shown by arrow A), and the air direction of the air return port 1220 is front and back (as shown by arrow B).

[0051] The advantage of this design is that this staggered design can better avoid the air return short circuit phenomenon, and also avoid assembly errors, that is, air return short circuit phenomenon will not be caused by assembly errors.

[0052] As shown in the drawings, Figure 2 As shown in the drawings, in the air duct component 12, the air inlet port 1210 is a flat port or a trapezoidal flared port, and the air return port 1220 is a flat port or a trapezoidal flared port. Preferably, the air inlet port 1210 is a trapezoidal flared port, and the air return port 1220 is a flat port.

[0053] It should be noted that the flat port means that the air duct port remains in the original flat state without any expansion or flanging treatment, and the installation difficulty is smaller. The trapezoidal flared port means that the air duct port is expanded by mechanical processing to form a specific shape flared port, and the connection is more stable.

[0054] The advantage of this design is that it increases the port design diversity of the air inlet duct 121 and the air return duct, meets the installation requirements of different structures, and has wider adaptability.

[0055] As shown in the drawings, Figure 2 As shown in the drawings, in the air duct component 12, the drain mounting port 1201 is a circular hole. This design can better adapt the drain mounting port 1201 to the drain pipe 112 in the water receiving component 11.

[0056] For better understanding, the structure of the water receiving component 11 will be described in more detail.

[0057] As shown in Figure 4 , in the water receiving component 11, the bottom wall of the water receiving groove body 110 is provided with a drain port 111, and the opposite side walls of the water receiving groove body 110 are provided with a return air avoiding port 113 and an air inlet avoiding port 114.

[0058] As shown in Figure 4 , Figure 5 , in the water receiving component 11, the drain port 111 is a round hole or a petal hole. If the drain port 111 is a round hole, the drain flow rate is faster; if the drain port 111 is a petal hole, the petal holes are distributed at intervals in a circle, and part of the cold air can be blocked from leaking while draining.

[0059] As shown in Figure 3 , Figure 6 to Figure 9 , in the water receiving component 11, the drain pipe 112 has opposite two ends.

[0060] As shown in Figure 8 , Figure 9 , the drain pipe 112 is provided with a crimping groove 1121 on the side of one end close to the drain port 111, and the crimping groove 1121 is connected with the groove wall of the water receiving groove body 110 in a crimping manner. This design can ensure that the connection between the drain pipe 112 and the water receiving groove body 110 is more reliable.

[0061] As shown in Figure 6 , Figure 7 , the drain pipe 112 is provided with an 8-shaped port 1122 at one end away from the drain port 111. In actual processing, the 8-shaped port 1122 is formed by cutting and crimping the port part of one end of the drain pipe 112. This design can block foreign matters from entering the drain port 111 and block part of the cold air from leaking while meeting the drainage function.

[0062] As shown in Figure 10 , Figure 11 , the refrigerator provided by the utility model at least includes a freezing box 3, a refrigerating box 4, and an evaporator 2 and a water pan and air duct integrated structure 1 arranged between the inner liner of the freezing box 3 and the inner liner of the refrigerating box 4, and the water pan and air duct integrated structure 1 is located at the lower part of the evaporator 2 and circulates cold air with the refrigerating box 4. Among them, the water pan and air duct integrated structure 1 has been described in detail in the foregoing, and will not be repeated here.

[0063] For the refrigerator in the utility model, since the water pan and air duct integrated structure 1 is integrally formed, the water pan and air duct integrated structure 1 can be integrally assembled to the lower part of the evaporator 2 in the inner liner, which reduces the assembly difficulty and improves the overall assembly quality.

[0064] Preferably, as shown in Figure 10 , Figure 11As shown, the freezer 3 and the refrigerator 4 are arranged in an up-down manner, the evaporator 2 is arranged at the back of the inner liner of the freezer 3, and the water pan and air duct integrated structure 1 is arranged at the back of the inner liner of the freezer 3 and is located below the evaporator 2. For the water pan and air duct integrated structure 1, the aluminum water pan part 11 and the air duct part 12 are pressed and integrated into one, forming an integrally formed part, the water pan and air duct integrated structure 1 contains the air inlet 1210 and the air return 1220, and also contains the drain port 111. Meanwhile, the air inlet 1210 and the air return 1220 are arranged in a staggered manner, the air direction of the air inlet 1210 is an up-down direction (arrow A), and the air direction of the air return 1220 is a front-rear direction (arrow B).

[0065] The water pan and air duct integrated structure and the refrigerator provided by the utility model adopt the centralized arrangement of the drain port, the air inlet and the air return on one integrated part, reduce the number of parts, and improve the overall assembly efficiency and quality. In addition, a new drain pipe is provided, one end of the drain pipe is cut and pressed into a '8' shape, and the drain port is blocked from foreign matter and cold air leakage.

[0066] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
