Description

Technical Field

[0001] The utility model belongs to the technical field of the air duct structure of a refrigerator, and particularly relates to an installation structure of a refrigerating air duct and a refrigerator thereof. Background Art

[0002] The refrigerating air duct of a refrigerator plays a crucial role inside the refrigerator. It is responsible for transferring cold air from the freezer or the refrigeration system to the refrigerating chamber to keep the food in the refrigerating chamber fresh and at an appropriate temperature. Currently, for the installation of the refrigerating air duct, mainly the plastic air duct joint, the electric air damper, and the foam fixing seat are first assembled, and then pre-assembled together with the refrigerating box liner and the freezing box liner for foaming. Subsequently, after a sealing sponge is pasted at the bottom of the refrigerating air duct, it is installed into the foamed box body, and sealed by squeezing the above-mentioned foam fixing seat against the refrigerating air duct to ensure that there is no air leakage at the bottom of the refrigerating air duct. However, due to the reasons of the foaming process and the installation method, it is difficult to ensure the consistency of the process, that is, it is impossible to ensure the consistency of the air duct structure of each refrigerator produced, so there will still be a situation of air leakage at the bottom of the refrigerating air duct. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above problems existing in the prior art, and provide an installation structure of a refrigerating air duct and a refrigerator thereof. A air supply socket is arranged between the refrigerating air duct and the foam fixing seat, and the installation between the air supply socket and the foam fixing seat is not affected by the foaming process and the installation method, etc., and can effectively avoid air leakage at the bottom of the refrigerating air duct.

[0004] To achieve the above technical purpose and reach the above technical effect, the utility model is realized through the following technical solutions:

[0005] In the first aspect, the utility model provides an installation structure of a refrigerating air duct, including:

[0006] An air duct joint assembly, a foam fixing seat is arranged at the top of the air duct joint assembly, an air duct interface is opened on the foam fixing seat, and a sinking groove communicated with the air duct interface is opened at the top of the foam fixing seat;

[0007] An air supply socket, the air supply socket includes an air supply socket seat, an air supply socket upper frame arranged at the top of the air supply socket seat, and an air supply socket lower frame arranged at the bottom of the air supply socket seat. A ventilation opening is opened at the top of the air supply socket seat, the air supply socket upper frame and the air supply socket lower frame are communicated through the ventilation opening, and the air supply socket seat is arranged in the sinking groove;

[0008] A refrigerating air duct, the bottom of the refrigerating air duct is sleeved outside the air supply socket upper frame;

[0009] A freezing air duct, which is used for transmitting cold air to the refrigerating air duct.

[0010] Further, the air supply socket base is fixed in the sinking groove by means of adhesive connection.

[0011] Further, the refrigerating air duct is fixed to the outside of the upper frame of the air supply socket by means of adhesive connection.

[0012] Further, the bottom of the refrigerating air duct is fixed to the air supply socket base by means of adhesive connection.

[0013] Further, the lower frame of the air supply socket is inserted into the air duct interface.

[0014] Further, the top of the upper frame of the air supply socket is 10 - 20 mm higher than the top of the foam fixing base.

[0015] In a second aspect, the present utility model provides a refrigerator, including the refrigerating air duct installation structure provided in the first aspect of the present invention.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The present utility model provides a refrigerating air duct installation structure and its refrigerator. An air supply socket is arranged between the refrigerating air duct and the foam fixing base. The installation between the air supply socket and the foam fixing base is not affected by the foaming process and installation methods, etc., which can effectively avoid air leakage at the bottom of the refrigerating air duct, thereby improving the product quality of the refrigerator.

[0018] 2. In the present utility model, since the cold air is transmitted to the refrigerating air duct through the freezing air duct, if the cold air flows out between the refrigerating air duct and the foam fixing base, it needs to pass through the air supply socket base first. Since the air supply socket base is arranged in the sinking groove at the top of the foam fixing base and the air supply socket base is fixed in the sinking groove by means of adhesive connection, there will be no air leakage here; the cold air continues to be transmitted and then passes through the upper frame of the air supply socket. Since the top of the upper frame of the air supply socket is 10 - 20 mm higher than the top of the foam fixing base, if the cold air wants to flow out between the refrigerating air duct and the foam fixing base, it must climb over this distance and then come down. And since the flow direction of the cold air is towards the negative pressure direction, there will be no air leakage here either.

[0019] 3. In the present utility model, an air supply socket is provided, which has a simple structure and does not change the previous assembly process, and the installation is fast and convenient. Description of the Drawings

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0030] As Figures 1 to 6 shown, the present utility model provides a refrigerator air duct installation structure, including an air duct joint assembly 1, an air supply socket 4, a refrigerator air duct 11, and a freezer air duct 10.

[0031] As Figures 1 to 2 shown, the air duct joint assembly 1 is arranged between the freezer liner 8 and the refrigerator liner 9 of the refrigerator 100 and is used for connecting the refrigerator air duct 11 and the freezer air duct 10.

[0032] As Figures 3 to 6As shown in the figure, a foam fixing seat 2 is provided on the air duct joint assembly 1. Specifically, the bottom of the foam fixing seat 2 is installed inside the air duct joint assembly 1. An air duct interface 20 is provided on the foam fixing seat 2, and a sinking groove 3 communicating with the air duct interface 20 is provided at the top of the foam fixing seat 2;

[0033] The air supply socket 4 includes an air supply socket seat 6, an air supply socket upper frame 5 provided at the top of the air supply socket seat 6, and an air supply socket lower frame 7 provided at the bottom of the air supply socket seat 6. A ventilation opening is provided at the top of the air supply socket seat 6, and the air supply socket upper frame 5 and the air supply socket lower frame 7 are communicated through the ventilation opening; specifically, the air supply socket seat 6, the air supply socket upper frame 5, and the air supply socket lower frame 7 are integrally designed;

[0034] The air supply socket seat 6 is arranged in the sinking groove 3. Specifically, the air supply socket seat 6 is fixed in the sinking groove 3 by means of adhesive connection. More specifically, the air supply socket seat 6 is adhered to the sinking groove 3 by double-sided tape;

[0035] The air supply socket lower frame 7 is inserted into the air duct interface 20;

[0036] In addition, the top of the air supply socket upper frame 5 is 10 - 20 mm higher than the top of the foam fixing seat 2. During actual installation, the refrigerating air duct 11 is sleeved outside the air supply socket upper frame 5. Therefore, if the cold air here needs to flow out, it needs to cross this 10 - 20 mm height to flow out. When the cold air is transmitted from the freezing air duct 10 to the refrigerating air duct 11, it flows in the negative pressure direction. Therefore, there is no air leakage here;

[0037] The bottom of the refrigerating air duct 11 is sleeved outside the air supply socket upper frame 5. Specifically, the refrigerating air duct 11 can be fixed outside the air supply socket upper frame 5 by means of adhesive connection. Moreover, the bottom of the refrigerating air duct 11 can also be fixed to the air supply socket seat 6 by means of adhesive connection;

[0038] The freezing air duct 10 is used to transmit cold air to the refrigerating air duct 11.

[0039] The specific installation process of this refrigerating air duct installation structure is as follows:

[0040] S1: Installation of the air supply socket 4

[0041] After the foaming of the refrigerator 100 box body is completed, insert the air supply socket lower frame 7 of the air supply socket 4 into the foam fixing seat 2, install the air supply socket upper frame 5 into the sinking groove 3 of the foam fixing seat 2, and firmly fix the air supply socket seat 6 and the foam fixing seat 2 with double-sided tape. The height of the upper end 5 of the air supply socket is 10 - 20 millimeters higher than the foam fixing seat 2;

[0042] S2: Installation of the refrigerating air duct 11

[0043] First, the air supply socket upper frame 5 of the air supply socket 4 is inserted into the refrigeration air duct 11 , and then the refrigeration air duct 11 is fixed to complete the installation of the refrigeration air duct 11 .

[0044] The flow path of cold air inside the refrigerator 100 is as follows: cold air flows from the freezing air duct 10 through the air duct connector 1 and the air supply socket 4 to the refrigeration air duct 11;

[0045] Therefore, if the cold air wants to leak out from the bottom of the refrigeration air duct 11, the first case is that it flows out from between the foam fixing base 2 and the air supply socket seat 6. Since the foam fixing base 2 is made into a sink 3, and the foam fixing base 2 and the air supply socket seat 6 are firmly glued with double-sided tape, there will be no air leakage here; the second case is that the air leaks between the refrigeration air duct 11 and the foam fixing base 2. Since the top of the air supply socket upper frame 5 is 10 to 20 mm higher than the top of the foam fixing base 2, that is, the air supply socket 4 is inserted into the refrigeration air duct 11 by 10 to 20 mm, the cold air must climb over this height and then come down before it can flow out. Since the cold air flows in the refrigerator 100 in the direction of negative pressure, there will be no air leakage here either.

[0046] The installation between the air supply socket 4 and the foam fixing seat 2 is not affected by the foaming and the process, so the air leakage at the bottom of the refrigeration air duct is better avoided.

[0047] like Figures 1 to 2 As shown, the utility model also provides a refrigerator, including the above-mentioned refrigeration air duct installation structure, and the refrigeration air duct installation structure here includes all the technical features of the above-mentioned refrigeration air duct installation structure.

[0048] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0049] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
