DETAILED DESCRIPTION

[0036] Embodiments of the present application are described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the drawings, in which the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are for the purpose of explanation only, and are not to be understood as limiting the present application.

[0037] In modern refrigeration equipment, air-cooled refrigerators are widely used due to their high efficiency and fast refrigeration capacity. However, there are some significant technical problems in the design of traditional air-cooled refrigerators, especially the problem of uneven distribution of cold air. Specifically, in the related art, the fan is usually arranged on one side of the mechanical room, which causes the cold air to be mainly concentrated in this area, so that other areas inside the cabinet cannot be effectively cooled. This design not only affects the overall refrigeration effect, but also can cause the quality of food preservation to decrease and the energy consumption to increase.

[0038] Based on the above considerations, an embodiment of the present application provides a refrigerator, which can spread cold air to each area inside the cabinet and improve the overall refrigeration effect.

[0039] The refrigerator according to an embodiment of the present application is described below with reference to Figures 1-5

[0040] Please refer to​Figure 1 and Figure 2 The embodiment of the present application provides a refrigerator 1, which comprises a cabinet 11, an air duct module 12, a door body 13, an air guide shell 14 and a fan 15.

[0041] The cabinet 11 provides a storage space for food and other articles, and is used for containing articles that need to be refrigerated or frozen. The cabinet 11 can be made of a heat preservation material, which can effectively isolate the influence of the external environment and keep the internal temperature stable.

[0042] The air duct module 12 is arranged in the cabinet 11, and the air duct module 12 is provided with an air outlet 121.

[0043] The air duct module 12 serves as a cold source of the refrigerator 1, and the air duct module 12 is provided with an evaporator, so as to exchange heat with air entering the air duct module 12 to refrigerate. The air duct module 12 can also be provided with an air return port. The air in the cabinet 11 enters the air duct module 12 through the air return port, exchanges heat with the evaporator to be cooled and converted into cold air, and is then discharged to the outside of the air duct module 12 through the air outlet 121, so as to refrigerate the cabinet 11. The position of the air return port on the air duct module 12 is not limited, and the air return port can be arranged at the bottom of the air duct module 12.

[0044] The door body 13 is arranged at the opening of the cabinet 11, and is used for closing the cabinet 11 to prevent the cold air from leaking and keep the internal temperature of the refrigerator 1 stable. In general, the covering area of the door body 13 is large, and the door body 13 can cover the entire space of the cabinet 11. The door body 13 is used to bear the air guide shell 14, so as to facilitate the uniform distribution of cold air in the cabinet 11.

[0045] The door body 13 can adopt a double-layer or multi-layer structure, which can increase the heat preservation effect and provide installation space for the air guide shell 14.

[0046] The air guide shell 14 is arranged on the door body 13, and the air guide shell 14 comprises an air inlet 141 and an air outlet 142. The air inlet 141 is at least partially connected with the air outlet 121.

[0047] The air guide shell 14 comprises the air inlet 141 and the air outlet 142, and the air inlet 141 and the air outlet 142 are in communication with each other. By connecting the air inlet 141 with at least part of the air outlet 121, at least part of the cold air blown out of the air outlet 121 can enter the air inlet 141. In the case that the air inlet 141 is partially connected with the air outlet 121, the air outlet 142 and the air outlet 121 jointly deliver cold air into the cabinet; in the case that the air inlet 141 is connected with all the air outlets 121, cold air is delivered into the cabinet only through the air outlet 142.

[0048] By setting the air outlet 142 on the door body 13, the coverage range of the air outlet 142 is increased, for example, the air outlet 142 is set at the end of the door body 13 away from the air duct module 12, which breaks the position limit of the air duct module 12. The cold air received by the air inlet 141 is discharged through the air outlet 142, which enables the cold air to be well distributed to each area inside the cabinet 11, improves the circulation effect of the cold air, and improves the refrigeration effect.

[0049] In an example, the air outlet 142 can be provided with multiple air outlets spaced from each other to further increase the coverage range of the air outlet 142. It should be noted that the number and position of the air outlet 142 are not limited and can be flexibly adjusted according to different shapes and sizes of the refrigerator 1.

[0050] The fan 15 is in communication with the air guide shell 14.

[0051] By communicating the fan 15 with the air guide shell 14, the fan 15 generates wind power by rotating, which drives the cold air to enter the air inlet 141 from the air outlet 121 and blow to the air outlet 142. The fan 15 generates wind power by rotating, which enhances the flow of cold air and ensures that the cold air can quickly reach each area inside the cabinet 11.

[0052] It should be noted that the installation position of the fan 15 is not limited, and the fan 15 can be provided in the air duct module 12, in the air guide shell 14, or in both the air duct module 12 and the air guide shell 14 to further improve the circulation efficiency.

[0053] Taking the air outlet 142 provided with multiple air outlets as an example, in actual execution, by setting the air guide shell 14 in the door body 13, the cold air first flows from the cabinet 11 to the air guide shell 14 in the door body 13. The air inlet 141 on the air guide shell 14 is at least partially connected to the air outlet 121 on the air duct module 12. After the cold air enters the air guide shell 14, it is evenly blown to the multiple air outlets 142 by the action of the fan 15. The design of the multiple air outlets 142 enables the cold air to enter the cabinet 11 from different directions, thereby achieving uniform distribution of the cold air. Since the cold air can be evenly distributed, each area inside the cabinet 11 can be effectively cooled, avoiding the problem of cold air concentrated on the mechanical room side in the traditional design. Through the action of the fan 15, the cold air forms a stable circulation system in the cabinet 11, improving the flowability of the cold air and reducing the loss of the cold air, thereby improving the overall refrigeration efficiency.

[0054] According to the refrigerator 1 of the embodiment of the present application, the air guide shell 14 is arranged in the door body 13, and the fan 15 is communicated with the air guide shell 14, so that the cold air in the air duct module 12 is driven by the fan 15 to enter the air guide shell 14 through the air inlet 141, and then is blown out through the air outlet 142. The covering area of the door body 13 is large, the air outlet 142 can better distribute the cold air to each area in the cabinet 11, improve the uniformity of refrigeration, and improve the overall refrigeration effect.

[0055] Please refer to Figure 3 and Figure 4 According to some embodiments of the present application, the air guide shell 14 can include an air inlet cavity 143 and an air outlet cavity 144. The air inlet 141 can be communicated with the air inlet cavity 143, and at least part of the projection of the air outlet 121 on the air guide shell 14 is located in the air inlet cavity 143; the air outlet cavity 144 can be communicated with the air inlet cavity 143, and the air outlet 142 is communicated with the air outlet cavity 144; the fan 15 can be arranged in the air inlet cavity 143, or in the air outlet cavity 144, or between the air inlet cavity 143 and the air outlet cavity 144.

[0056] The air guide shell 14 forms the air inlet cavity 143 and the air outlet cavity 144 which are communicated with each other, the air inlet 141 is communicated with the air inlet cavity 143, and the cold air enters the air inlet cavity 143 through the air inlet 141. Among them, at least part of the projection of the air outlet 121 on the air guide shell 14 is located in the air inlet cavity 143, that is, at least part of the air outlet 121 is opposite to the air inlet cavity 143, which ensures that the cold air blown out from the air duct module 12 can better enter the air inlet cavity 143, reducing the loss of cold air in the transmission process.

[0057] A plurality of air outlets 142 are communicated with the air outlet cavity 144, and the cold air entering the air outlet cavity 144 can be blown to the inside of the cabinet 11 through the air outlet 142. Among them, the air outlet cavity 144 can cover as much area of the door body 13 as possible to improve the flexibility of the arrangement of the air outlet 142.

[0058] Among them, the installation position of the fan 15 has at least the following three installation modes:

[0059] First, the fan 15 can be installed in the air inlet cavity 143.

[0060] By arranging the fan 15 in the air inlet cavity 143, on the one hand, the fan 15 is arranged close to the air inlet 141, so that the negative pressure generated by the inlet of the fan 15 can improve the efficiency of the cold air entering the air inlet cavity 143; on the other hand, the rotation of the blades of the fan 15 drives the cold air to mix quickly, and the positive pressure generated by the outlet of the fan 15 improves the pressure in the air inlet cavity 143, reasonably distributes the pressure, and makes the wind speed of the cold air in the air inlet cavity 143 higher when entering the air outlet cavity 144, improves the delivery distance of the cold air, and ensures that the cold air can quickly reach each area inside the cabinet 11.

[0061] Secondly, the fan 15 can be installed in the air outlet cavity 144.

[0062] The fan 15 is arranged in the air outlet cavity 144 and is closer to the air outlet 142, so as to improve the air speed at the position of the air outlet 142 and improve the refrigeration effect.

[0063] Thirdly, the fan 15 can be installed between the air inlet cavity 143 and the air outlet cavity 144.

[0064] The fan 15 is installed between the two cavities and takes into account the air inlet and air outlet of the air guide shell 14, so that the comprehensive performance is more stable.

[0065] Please refer to Figure 3 and Figure 4 According to some embodiments of the present application, the air inlet cavity 143 can be provided with a mounting groove 1431, the mounting groove 1431 is provided with a mounting plate 1432, and the fan 15 can be installed on the mounting plate 1432.

[0066] The wall surface of the air inlet cavity 143 can be provided with the mounting groove 1431, and the mounting groove 1431 facilitates the positioning and installation of the fan 15.

[0067] In an example, the mounting plate 1432 can be the bottom wall of the mounting groove 1431, that is, the fan 15 is installed on the bottom wall of the mounting groove 1431.

[0068] In another example, the mounting groove 1431 can be a through groove, and the mounting plate 1432 is arranged on the mounting groove 1431, that is, the wall surface of the air guide shell 14 is provided with a through mounting groove 1431, the fan 15 is installed on the mounting plate 1432, and then the mounting plate 1432 is arranged on the mounting groove 1431, so that the mounting plate 1432 plays a role of supporting the installation platform of the fan 15, facilitating the installation and maintenance of the fan 15.

[0069] Taking the horizontal refrigerator 1 as an example, the door body 13 is located on the upper side of the box body 11 and also on the upper side of the air duct module 12, the air outlet 121 of the air duct module 12 is located on the lower side of the air guide shell 14, and therefore the air inlet 141 of the air guide shell 14 is located on the lower side of the air guide shell 14. The mounting groove 1431 can be arranged on the top wall of the air inlet cavity 143, and the fan 15 is installed on the top wall of the air guide shell 14 through the mounting plate 1432, so that the fan 15 can be opposite to the air inlet 141, the suction force generated by the air inlet 141 can be used to suck cold air into the air inlet cavity 143, the overall space layout is optimized, and the stability of the overall operation is ensured.

[0070] According to some embodiments of the present application, at least part of the fan 15 can be directly opposite the air outlet 121, so as to ensure that the cold air blown out of the air outlet 121 is directly captured by the fan 15 and guided into the air inlet cavity 143, so that the cold air flows more smoothly and the utilization efficiency of the cold air is improved.

[0071] Please refer to Figure 4 According to some embodiments of the present application, the air guide shell 14 can include a main shell 145 and an air inlet joint 146. The main shell 145 can be arranged in the door body 13, the air inlet joint 146 can be connected to one end of the main shell 145 and at least partially protrude from the door body 13 and be arranged corresponding to at least part of the air outlet 121, and the air inlet 141 can be arranged in the air inlet joint 146.

[0072] The main shell 145 is arranged in the door body 13 and is used to accommodate the fan 15 and form a channel for the cold air to flow. The air inlet joint 146 is arranged at one end of the main shell 145 to improve the stability of the flow direction of the cold air, that is, the cold air enters from one end of the main shell 145 and moves to the other end.

[0073] The main shell 145 can be provided with a fan 15 mounting position inside. The fan 15 is mounted in the main shell 145 and generates wind power by rotating to suck the cold air from the air inlet 141 and blow it to the air outlet 142. The main shell 145 can be made of a material with high corrosion resistance and strength to ensure reliability and durability during long-term use.

[0074] It should be noted here that the air duct module 12 generally has the air outlet 121 arranged thereon. In order to ensure the smoothness of the air outlet 121, the air outlet 121 of the air duct module 12 must be arranged in a spaced manner with the door body 13. By arranging the air inlet joint 146, one end of the air inlet joint 146 is connected to the main shell 145, the other end at least partially protrudes from the door body 13 and is arranged corresponding to at least part of the air outlet 121, and is connected to the air duct module 12. It can be understood that the air inlet 141 is arranged at the other end of the air inlet joint 146. The design of the extended air inlet joint 146 makes the air inlet 141 directly and stably connected to the air outlet 121 of the air duct module 12.

[0075] The air inlet joint 146 and the door body 13 can be provided with a sealing structure therebetween to ensure the sealing property and reduce the leakage amount of the cold air.

[0076] The air inlet joint 146 according to the embodiments of the present application reduces the loss of the cold air during transmission, improves the flow efficiency of the cold air, and is convenient to modify on the basis of not changing the original structure of the air duct module 12, saves the modification and production cost.

[0077] In some embodiments, the air inlet joint 146 can be integrally formed with the main housing 145, further reducing production costs and improving assembly efficiency, reducing the probability of air leakage and improving the stability of the device in use.

[0078] The air inlet joint 146 is connected to one end of the main housing 145 and at least partially extends out of the door body 13 to connect with the air duct module 12. The air inlet 141 is provided on the air inlet joint 146 to receive cold air from the air duct module 12.

[0079] Referring to Figure 2 and Figure 3 According to some embodiments of the present application, the periphery of the air inlet 141 can match at least part of the periphery of the air outlet 121 when the door body 13 is in a closed state.

[0080] It can be understood that when the door body 13 is opened, the air inlet joint 146 is separated from the air duct module 12, and when the door body 13 is closed, the stability of the air inlet 141 on the air inlet joint 146 contacting the air outlet 121 on the air duct module 12 needs to be ensured. By designing the periphery of the air inlet 141 to match at least part of the periphery of the air outlet 121, the air inlet 141 can be more closely fitted to the air duct module 12 when the door body 13 is closed. Specifically, the periphery of the air inlet 141 can match the shape of at least part of the air duct module 12. For example, the position of the air outlet 121 on the top of the air duct module 12 is arranged in an arc shape, and the side of the periphery of the air inlet 141 is arranged in an arc shape matching the shape of the air duct module 12, so that the periphery of the air inlet 141 is fitted to the air duct module 12 when the door body 13 is closed.

[0081] When the door body 13 is in a closed state, the periphery of the air inlet 141 is in sealing connection with the air duct module 12, which can prevent cold air leakage and ensure effective transmission of cold air. For example, a sealing ring or gasket can be provided on the periphery of the air inlet 141 to further enhance the sealing effect; or it can be achieved by mechanical pressing, magnetic attraction or other fixing methods to ensure that a good sealing state is always maintained when the door body 13 is closed.

[0082] Referring to Figure 2 and Figure 3 According to some embodiments of the present application, at least part of the air outlet 121 is located on the side wall of the air duct module 12 facing the center of the cabinet 11 and / or the top wall of the air duct module 12 facing the opening of the cabinet 11, and the lower end of the air inlet joint 146 is provided with an extension section 1461, which cooperates with at least part of the side wall and / or the top wall where the air outlet 121 is located when the door body 13 is in a closed state.

[0083] In the related art, the air outlet of the air duct module is generally arranged towards the center of the cabinet so that the cold air can fill the cabinet as soon as possible, and therefore at least part of the air outlet is arranged on the side wall of the air duct module towards the center of the cabinet.

[0084] In order not to affect the opening and closing of the door body 13, the air inlet joint 146 is not directly connected with the air duct module 12, and the air inlet joint 146 and the air duct module 12 are relatively moved in the height direction. When the air outlet 121 is arranged on the top wall of the air duct module 12, the air inlet joint 146 can be pressed against the air duct module 12 to ensure the sealing effect, and the extension section 1461 can increase the contact area between the air inlet joint 146 and the top wall to further improve the sealing effect.

[0085] When part of the air outlet 121 is arranged on the side wall, the extension section 1461 is arranged at the lower end of the air inlet joint 146, and the extension section 1461 is matched with at least part of the air outlet 121 arranged on the side wall, thereby increasing the contact area between the air inlet joint 146 and the air duct module 12, improving the sealing effect, reducing the risk of cold air flowing out from the lower end of the air inlet joint 146, and improving the transmission efficiency of the cold air.

[0086] Please refer to Figure 4 According to some embodiments of the present application, the end of the main shell 145 away from the air inlet joint 146 can be provided with an air outlet passage 147, and the air outlet passage 147 can include a main air duct and a plurality of branch air ducts in communication with the main air duct.

[0087] The end of the main shell 145 away from the air inlet joint 146 is provided with the air outlet passage 147, and the cold air entering the main shell 145 from the air inlet joint 146 is blown to the air outlet passage 147 under the action of the fan 15. The air outlet passage 147 can include a main air duct and a plurality of branch air ducts in communication with the main air duct. The main air duct is the main flow path of the cold air blown out from the fan 15, which ensures that the cold air can be uniformly distributed to each branch air duct. The branch air duct is in communication with the main air duct and is used to disperse the cold air to different air outlets 142 to achieve more uniform distribution of the cold air. For example, the main air duct can extend along the width direction of the refrigerator 1, and the plurality of branch air ducts can be distributed on both sides of the main air duct in the thickness direction of the refrigerator 1, which is simple in structure and covers the entire cabinet 11 as much as possible.

[0088] The air outlet 142 has at least two arrangement modes on the air outlet passage 147 as follows:

[0089] First, the branch air duct is provided with the air outlet 142.

[0090] Each branch air duct is provided with the air outlet 142 at least at the end away from the main air duct. By arranging the air outlet 142 on the branch air duct, the cold air can enter the interior of the cabinet 11 from multiple directions, thereby improving the uniformity of the cold air distribution.

[0091] Secondly, the main air duct and the branch air duct are both provided with air outlets 142.

[0092] Each branch air duct is provided with an air outlet 142 at least at one end away from the main air duct, and the main air duct is provided with an air outlet 142 at least at one end away from the air inlet joint 146. By providing the air outlets 142 on the main air duct and the branch air duct, the cold air can not only flow out through the branch air duct, but also directly flow out through the main air duct, further improving the coverage range and uniformity of the cold air.

[0093] Please refer to Figure 4 In some embodiments, the portion of the main shell 145 provided with the air inlet cavity 143 is greater than the width of the main air duct in the thickness direction of the refrigerator 1, and one end of the main air duct is in communication with the portion of the main shell 145 provided with the air inlet cavity 143. By designing the size of the air inlet cavity 143 to be larger, the mixing and pressurization of the cold air can be facilitated. In order to reduce the resistance of gas flow, the portion of the main shell 145 provided with the air inlet cavity 143 can be provided with a guide slope at the position connected with the main air duct, and the guide slope can be arc-shaped.

[0094] Please refer to Figure 3 and Figure 4 According to some embodiments of the present application, the air outlet 142 can be provided with a plurality of air outlets, and the direction of at least one air outlet 142 can be at an angle to the side wall of the cabinet 11; and / or, the direction of at least one air outlet 142 can be parallel to the side wall of the cabinet 11.

[0095] The direction of the air outlet 142 is not specifically limited and can be designed according to requirements, and the following implementation modes are provided:

[0096] Firstly, the directions of all air outlets 142 are arranged at an angle to the side wall of the cabinet 11.

[0097] The direction of the air outlet 142 is at an angle to the side wall of the cabinet 11. This design can make the cold air blow into the cabinet 11 at a certain angle, thereby more effectively covering the entire internal space of the cabinet 11. The air outlet angles of the air outlets 142 can be the same or different, and exemplarily, the angle between the air outlet 142 and the side wall of the cabinet 11 can be 45 degrees, 60 degrees or other suitable angles, and the specific angle can be adjusted according to actual requirements.

[0098] Secondly, the directions of all air outlets 142 are parallel to the side wall of the cabinet 11.

[0099] The orientation of the air outlet 142 is parallel to the side wall of the cabinet 11, that is, the orientation of the air outlet 142 is vertically downward. When the air outlet 142 is located in the middle of the door body 13, this design can make the cold air directly blow to the articles in the cabinet 11, improve the freezing efficiency, and ensure the refrigeration effect. When the air outlet 142 is located on the side of the door body 13, this design can make the cold air flow along the side wall of the cabinet 11, reduce the possibility of directly impacting the articles, and protect part of the food from being directly impacted by the cold air.

[0100] Thirdly, the orientation of part of the air outlet 142 is arranged at an angle with the side wall of the cabinet 11, and the orientation of part of the air outlet 142 is parallel to the side wall of the cabinet 11.

[0101] Combining the above two designs of the air outlet 142, the design is flexible, and can be flexibly designed according to the needs. The air outlet 142 can be arranged according to the angle, and the internal space of the cabinet 11 can be partitioned. Some areas are directly blown by cold air, and some areas are not directly blown by cold air, thereby improving the overall use experience of the refrigerator 1.

[0102] Please refer to Figure 4 and Figure 5 According to some embodiments of the present application, the inner plate 131 of the door body 13 can be provided with a through hole 132 for the air outlet 142 to pass through.

[0103] The air guide shell 14 in the present application is an integrally formed independent part, which is simple to manufacture and low in production cost. Moreover, the air guide shell 14 has good internal air duct sealing performance, low cold air leakage probability, and low probability of causing the door body 13 to dew and accumulate water inside due to leakage of cold air in the door body 13.

[0104] The assembly is also relatively simple. The inner plate 131 of the door body 13 is provided with a through hole 132 for the air outlet 142 to pass through. The position of the through hole 132 should correspond to the position of the air outlet 142, so that the size of the through hole 132 needs to match the size of the air outlet 142, so as to ensure that the air outlet 142 can pass through the through hole 132 tightly, while not affecting the flow of cold air. During assembly, the air outlet 142 of the air guide shell 14 passes through the through hole 132, and then the outer plate and the inner plate 131 of the door body 13 are buckled. The outer plate and the inner plate 131 of the door body 13 are filled with heat insulation foam, so as to ensure the heat insulation performance of the door body 13, and also fix the air guide shell 14.

[0105] In some embodiments, a sealing member can be arranged between the air guide shell 14 and the through hole 132.

[0106] Because the through hole 132 is arranged on the inner plate 131, a sealing member is arranged between the air guide shell 14 and the through hole 132 to seal the gap between the air guide shell 14 and the through hole 132. When the foam is filled, the probability of overflow is reduced, the assembly quality is improved, and cold air leakage is avoided.

[0107] According to some embodiments of the present application, the air outlets 121 can be provided in multiple numbers distributed along the height direction, and the air inlet 141 can be connected to at least part of the air outlets 121 at the uppermost end.

[0108] The air outlets 121 can be provided in multiple numbers distributed along the height direction, so that the cold air can enter the cabinet 11 from different heights, further improving the uniformity of the cold air distribution. The number and position of the air outlets 121 are not limited, and can be two, three, etc. Taking the case where the air outlets 121 are provided in two numbers as an example, one air outlet 121 can be arranged at the top of the air duct module 12, and the other air outlet 121 can be arranged at the middle of the air duct module 12 in the height direction.

[0109] The air inlet 141 can be connected to at least part of the air outlets 121 at the uppermost end, facilitating the connection of the air inlet 141 on the door body 13 to the air duct module 12, ensuring that sufficient cold air enters the air guide shell 14, and improving the flow efficiency of the cold air.
