Detailed Description
Fig. 1 is a schematic configuration diagram of a refrigerator 10 according to one embodiment of the present invention.
The refrigerator 10 may generally include an inner container 320 and a connecting duct assembly 240. The inner container 320 is used to be assembled with the cabinet of the refrigerator 10 to form the cabinet 110. The connecting air duct assembly 240 is assembled to the inner container 320 and is used for guiding air to the storage compartment defined by the inner container 320. The inner container 320 may refer to a common inner container 320 such as a refrigerating inner container 320, a freezing inner container 320 or a temperature-changing inner container 320.
Fig. 2 is a schematic configuration diagram of a partial structure of the refrigerator 10 according to an embodiment of the present invention, and fig. 3 is a schematic configuration diagram of another view angle of the partial structure of the refrigerator 10 shown in fig. 2, in which an inner container 320 equipped with a connecting duct assembly 240 is shown.
Fig. 4 is a schematic structural view of an inner container 320 of the refrigerator 10 according to one embodiment of the present invention. The inner container 320 is provided with an air inlet 326. The air inlet 326 penetrates through the wall of the inner container 320, thereby communicating the inside and the outside of the inner container 320.
Fig. 5 is a schematic assembly view of the induced air duct assembly 210 and the connecting air duct assembly 240 of the refrigerator 10 according to one embodiment of the present invention. The connecting air duct assembly 240 is located outside the inner container 320 and has a connecting air duct housing 241, the inside of the connecting air duct housing 241 defines a connecting air duct 241b, and a portion of the connecting air duct housing 241 is inserted into the air inducing opening 326 to make the connecting air duct 241b extend into the inner container 320, so as to guide the air flow outside the inner container 320 to the inside of the inner container 320 through the connecting air duct 241 b.
By inserting a part of the connecting air duct case 241 into the air inducing opening 326, the connecting air duct 241b defined by the connecting air duct case 241 extends from the air inducing opening 326 to the inner container 320 along with the connecting air duct case 241, so that the heat exchange air flowing through the connecting air duct 241b can flow out of the inner container 320 and supply cold to the inner container 320.
By inserting a part of the connecting air duct casing 241 into the air inducing opening 326 of the inner container 320 and extending the connecting air duct 241b into the inner container 320, an overlapping structure can be formed, so that the connecting air duct 241b can be used for realizing the air guiding function, and simultaneously, the displacement of the connecting air duct assembly 240 can be limited by the overlapping structure, thereby reducing or avoiding the position change of the connecting air duct assembly 240 of the refrigerator 10 in the foaming process, and ensuring the smooth air supply path of the refrigerator 10.
The inner container 320 may receive heat exchange air flow from the outside and implement refrigeration by using the connecting duct assembly 240 to guide air. The evaporator does not need to be additionally arranged inside the inner container 320. By adopting the scheme of the embodiment, the number of evaporators of the multi-chamber refrigerator 10 can be reduced, the structure of the refrigerator 10 is simplified, and the manufacturing cost is reduced. Since the evaporator does not need to be additionally disposed inside the inner container 320, the effective volume of the inner container 320 can be increased to meet the storage requirement of a user.
Fig. 6 is a schematic view of an assembly structure of the air inducing duct assembly 210 and the connecting duct assembly 240 of the refrigerator 10 according to an embodiment of the present invention, in which the inner concave insertion part 211a, the outer convex insertion part 241a, and the inner container 320 are shown.
In some alternative embodiments, the connecting duct housing 241 has a male insertion portion 241a protruding toward the outside, and the air induction opening 326 is inserted by using the male insertion portion 241 a.
In the following description, the terms "inner", "outer", "concave", "convex" and the like are used in terms of the actual usage of the respective components. For example, the phrase "protruding outward from the connecting duct case 241" means that the main body portion protrudes from the connecting duct case 241.
It should be noted that, since the outer convex insertion part 241a protrudes from the main body part of the air duct housing 241, the outer convex insertion part 241a needs to extend into the inner container 320 through the air inlet 326. The opening size of the air inducing opening 326 may be slightly larger than the outer size of the outer convex insertion part 241 a.
In some optional embodiments, the air inducing opening 326 is an optical hole penetrating through the thickness direction of the liner wall of the liner 320 and allowing the outer convex insertion portion 241a to be inserted into the inner concave insertion portion 211 a. For example, the air inducing openings 326 may be provided on any one of the lateral side walls of the inner container 320.
An air supply outlet 248 communicated with the air duct 241b is arranged on the outer end surface of the outer convex inserting part 241 a. The "outer end surface of the outer convex mating part 241 a" is located at the protruding end of the outer convex mating part 241a with respect to the protruding direction of the outer convex mating part 241 a.
For example, when the male mating part 241a protrudes rightward with respect to the main body part of the connecting duct housing 241, the outer end surface of the male mating part 241a refers to the end surface located on the rightmost side of the male mating part 241 a. When the outer male mating part 241a protrudes leftward with respect to the main body part of the connecting duct casing 241, the outer end surface of the outer male mating part 241a refers to the end surface located at the leftmost side of the outer male mating part 241 a.
The air supply opening 248 is formed on the outer end surface of the outer convex inserting part 241a, so that the air supply opening 248 can be prevented from being shielded when the outer convex inserting part 241a is inserted into the inner container 320, and the air passage can be ensured to be smooth.
In some optional embodiments, the refrigerator 10 may further include another inner container 310, which is provided with an air supply opening 318 and is arranged in parallel with the inner container 320 along a transverse direction. For the sake of convenience, the "another liner 310" may be named as a second liner 320, and the liner 320 may be named as a first liner 320. The first inner container 320 and the second inner container 320 may be respectively selected from any one of common inner containers such as a refrigerating inner container, a freezing inner container or a temperature changing inner container.
The connecting air duct assembly 240 is clamped between the two inner containers, and a communication port 246 that is communicated with the connecting air duct 241b and is opposite to the air supply port 248 is further formed on the connecting air duct casing 241, and the communication port 246 is connected to the air supply port 318 and is used for allowing the air flow from the air supply port 318 to enter the connecting air duct 241 b.
At this time, the evaporator may be disposed only inside any one of the two inner containers, and the connecting duct assembly 240 may be used to guide the heat exchange air flow passing through the evaporator into the other inner container 310, so as to achieve the cold energy sharing.
In some alternative embodiments, the aforementioned outer convex insertion part 241a (which may be named as a first outer convex insertion part 241a) is located at one lateral side of the connecting air duct housing 241, and another outer convex insertion part 241a (which may be named as a second outer convex insertion part 241a) protruding towards the outside and inserted into the air supply opening 318 is further formed at the other lateral side of the connecting air duct housing 241, so that the connecting air duct 241b simultaneously extends into the two inner containers 320. The communication port 246 may be opened on the outer end surface of the second male plug portion 241 a.
When the connecting air duct assembly 240 is clamped between the two inner containers and extends into the two inner containers simultaneously, the connecting air duct assembly 240 can be firmly fixed between the two inner containers in the foaming process, so that the connecting air duct assembly 240 is firmly assembled on the inner containers 320, and the 'transverse sharing' of the cooling capacity is realized.
The interior of the first inner container 320 may define a first low-temperature storage region 322 for storing objects. The inside of the second inner container 310 may define an evaporator mounting region 311 for mounting an evaporator and a second low-temperature storage region 312 for storing articles, which is located at a front side of the evaporator mounting region 311. The heat exchange air flow through the evaporator can flow to both the second low temperature storage area 312 and the first low temperature storage area 322 defined by the first inner container 320 through the connecting duct assembly 240.
The second inner container 310 may further have a first air return 328 formed in a wall thereof for allowing the air flow passing through the first inner container 320 to flow out of the first inner container 320. The second air return port 319 is disposed on the wall of the second inner container 310, and is connected to the first air return port 328 through another connecting duct assembly 240, and is used for allowing the return air flowing through the first inner container 320 to flow back to the evaporator installation region 311.
In some alternative embodiments, the connecting duct housing 241 of the connecting duct assembly 240 is formed with overlapping portions overlapping with the side end top wall of at least one of the first and second inner containers 320 and 320, and when the connecting duct assembly 240 is clamped between the first and second inner containers 320 and 320, the overlapping portions are supported by the side end top wall of the inner container 320, thereby improving the prevention of shaking.
The top wall of the side end of the first inner container 320 is a wall surface of the first inner container 320, which is a boundary area between the top wall and the side wall where the air inducing opening 326 is formed. The top wall of the side end of the second inner container 320 is a wall surface of the second inner container 320 where a boundary area between the side wall and the top wall of the air supply port 318 is formed.
In some optional embodiments, the refrigerator 10 may further include an induced air duct assembly 210 disposed inside the inner container 320 and having an induced air duct housing 211, where an induced air duct 211b is defined inside the induced air duct housing 211. And an inner concave insertion part 211a recessed towards the inner side is formed on the induced air duct housing 211, and the outer convex insertion part 241a is inserted into the inner concave insertion part 211a to realize the insertion fit. The phrase "recessed toward the inner side of the induced air duct housing 211" means that the induced air duct housing 211 is recessed in the main body.
That is, the induced air duct assembly 210 and the connecting air duct assembly 240 are inserted into each other at the induced air opening 326, so that a portion of the connecting air duct assembly 240 is inserted into the induced air duct assembly 210, and the induced air duct 211b is communicated with the connecting air duct 241 b.
The air duct connecting mode of the refrigerator 10 can be simplified and the assembling efficiency can be improved by inserting the induced air duct assembly 210 and the connecting air duct assembly 240 into each other at the induced air port 326, so that the air duct 211b and the connecting air duct 241b are communicated, and the assembling precision between the induced air duct assembly 210 and the induced air port 326 and the assembling precision between the connecting air duct assembly 240 and the induced air port 326 do not need to be considered.
The outer convex insertion part 241a is inserted into the inner concave insertion part 211a to communicate the induced air duct 211b and the connection air duct 241b, so that the method is simple and convenient, and high assembly precision is easy to guarantee. And only need change to induced air duct casing 211 and the forming die who connects air duct casing 241, can form the evagination grafting portion 241a and the indent grafting portion 211a of mutual grafting cooperation, the product homogeneity is good.
An air inlet 218 which is communicated with the air inducing duct 211b and is butted with the air supply outlet 248 is arranged on the inner end surface of the concave inserting-connecting part 211 a. The "inner end surface of the concave mating part 211 a" is located at a concave end of the concave mating part 211a with respect to a concave direction of the concave mating part 211 a.
When the male plug part 241a is inserted into the female plug part 211a, the outer end surface of the male plug part 241a abuts against the inner end surface of the female plug part 211 a. The air supply outlet 248 is formed in the outer end face of the outer convex insertion part 241a, the air inlet 218 is formed in the inner end face of the inner concave insertion part 211a, and the air inlet 218 and the air supply outlet 248 can be in seamless connection, so that the integration degree of the induced air duct 211b and the connecting air duct 241b is improved, and the air supply efficiency of the refrigerator 10 is improved.
In some alternative embodiments, the air duct assembly 210 is provided with an elastic member 270, and the elastic member 270 is disposed at a mutual pressing position of the inner concave insertion part 211a and the outer convex insertion part 241a in a force-deformable manner and is set to avoid the air supply opening 248 for being deformed by being pressed when the outer convex insertion part 241a is inserted into the inner concave insertion part 211a, so that the air inlet 218 and the air supply opening 248 are in sealed butt joint.
Fig. 7 is a schematic view of an assembly structure of the induced air duct assembly 210 and the connecting air duct assembly 240 of the refrigerator 10 according to another embodiment of the present invention, in which the inner concave insertion part 211a, the outer convex insertion part 241a, the inner container 320, and the elastic member 270 are shown.
The elastic member 270 may be made of an elastic sealing material for sealing the interface. In some embodiments, the resilient member 270 may be made of EPDM (Ethylene Propylene Diene Monomer) material, which is soft and seals well. In some alternative embodiments, the elastic member 270 may also be made of a high-density sponge.
By arranging the elastic member 270 on the induced air duct assembly 210 and making the elastic member 270 deform by being stressed on the inner concave insertion part 211a, the elastic member 270 deforms by being squeezed when the outer convex insertion part 241a is inserted into the inner concave insertion part 211a, so that the air inlet 218 and the air supply outlet 248 are in sealed butt joint, which is beneficial to improving the air duct connection quality of the refrigerator 10 and preventing air leakage and cold leakage.
When an installer inserts and fits the inner concave insertion part 211a and the outer convex insertion part 241a of the air inducing duct housing 211, the elastic member 270 moves synchronously along with the inner concave insertion part 211a and is pressed by the outer convex insertion part 241a and the inner concave insertion part 211a to deform during the moving process, so that the elastic member can be inserted into gaps between the contact parts of the outer convex insertion part 241a and the inner concave insertion part 211a and seal the gaps, therefore, the air inlet 218 and the air supply outlet 248 are in sealed butt joint, and the problems of air leakage and cold leakage can be reduced or avoided.
The respective contact portions of the male and female insertion parts 241a and 211a serve as mutual pressing portions between the male and female insertion parts 241a and 211 a. The elastic member 270 may be disposed at each contact portion where the male socket 241a is in press-contact with the female socket 211a, thereby sealing a gap between the contact portions.
In some alternative embodiments, the inner end surface of the female insertion part 211a and the outer end surface of the male insertion part 241a are pressed against each other and form the first pressing surface 201. The elastic member 270 includes a first annular elastic portion 271 disposed on the first pressing surface 201 and avoiding the air inlet 218.
The first pressing surface 201 and the outer end surface of the male plug 241a pressed against the first pressing surface 201 are vertically opposite to each other.
In some alternative embodiments, the inner circumferential surface of the inner concave socket portion 211a and the outer circumferential surface of the outer convex socket portion 241a are pressed against each other and form the second pressing surface 202. The elastic member 270 includes a second annular elastic portion 272 surrounding the second pressing surface 202 and fixedly connected to the first annular elastic portion 271 or integrally formed with the first annular elastic portion 271.
The second pressing surface 202 and the outer peripheral surface of the convex insertion part 241a pressed with the second pressing surface 202 are respectively opposite to each other in a shape like a Chinese character 'ba'.
