Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] As a component of a refrigerator's refrigeration system, the condenser is a type of heat exchanger that converts gas or vapor into liquid, quickly transferring heat from the tubes to the surrounding air. The condenser's operating process is a heat release process, so the condenser itself is typically quite hot. To improve the condenser's efficiency, the heat must be transferred away promptly.

[0003] The air-cooled condensers commonly used in refrigerators on the market currently mainly include: microchannel condensers and surface condensers. Among them, microchannel condensers are expensive and limited by the structure of the refrigerator itself. Some refrigerators only have a bottom cooling system, and the heat dissipation effect cannot meet the requirements. Therefore, an additional surface condenser is required. Surface condensers are divided into exposed condensers and built-in condensers. The overall cost of exposed condensers is lower than that of microchannel condensers, but they are usually placed on the outside of the rear wall of the refrigerator body, which is prone to dust accumulation. They are also easily bumped during the placement of the refrigerator, which affects the heat dissipation effect of the condenser. In addition, due to the appearance, some users do not accept refrigerators equipped with exposed condensers. Built-in condensers are relatively cheaper, but the condenser tube is attached to the inner side of the U shell and back panel with aluminum foil tape, which has low heat dissipation efficiency and high thermal resistance, which is not conducive to heat dissipation.

[0004] In general, the refrigerator condenser in the prior art has the problem of poor heat dissipation effect. Summary of the Invention

[0036] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0037] If the present invention involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.), the directions involved need to be defined. For example, "To clearly express the positions and directions described in this invention, the end closest to the operator is the proximal end, and the end away from the operator is the distal end." Alternatively, the paper surface or the depth direction of the refrigerator can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, this definition is not required.

[0038] In order to solve the problem of poor heat dissipation effect of a condenser of a refrigerator in the prior art, the present invention provides a refrigerator.

[0039] like Figure 1-5As shown, an embodiment of the present invention provides a refrigerator, comprising a cabinet and a door for opening and closing the cabinet, wherein a condenser assembly is provided on the upper end surface of the cabinet, and the condenser assembly comprises:

[0040] A cover plate 1 is provided on the upper end surface of the box body to form a housing with an accommodating space, and an air inlet hole 111 and an air outlet hole 121 are provided on the cover plate 1;

[0041] The fan 2 is disposed in the housing, and the air inlet 111 is located on the cover plate 1 and is disposed toward the fan 2 so that the fan 2 supplies air to the accommodating space through the air inlet 111;

[0042] a wind shield 3, the wind shield 3 respectively abutting against the upper end surface of the box body and the cover plate 1 to form an air duct, the fan 2 being located at one end of the air duct and configured to supply air to the air duct;

[0043] The condenser includes a condenser pipe 43 and an inlet portion 41 and an outlet portion 42 connected to both ends of the condenser pipe 43. The condenser pipe 43 is at least partially arranged on the trajectory of the wind running in the air duct.

[0044] Typically, the cover plate 1 can be configured to include a center plate 11 parallel to the upper end face of the box body and a plurality of folded edges 12 arranged toward the upper end face of the box body. The plurality of folded edges 12 are connected to the upper end face of the box body. This configuration can form a regular accommodation space on the upper end face of the box body. Of course, other configurations that can ensure that the cover plate 1 is connected to the upper end face of the box body to form an accommodation space are also feasible. The air inlet 111 is provided on the center plate 11, and the air exhaust 121 is provided on the folded edge 12. Furthermore, in order to improve the efficiency of air exhaust, a plurality of the air exhaust 121 are evenly arranged on each folded edge 12.

[0045] Furthermore, the air inlet hole 111 is configured to match the fan 2. The fan 2 can pass through the air inlet hole 111 and be fixedly connected to the upper end surface of the housing. This configuration not only facilitates the fan 2 to draw air from the air inlet hole 111, but also facilitates the installation of the fan 2 on the upper end surface of the housing through the air inlet hole 111. Of course, if the fan 2 is damaged, it can also be removed from the upper end surface of the housing through the air inlet hole 111, facilitating later maintenance and replacement.

[0046] Of course, the condenser assembly may further include a cover net 21, which is arranged on the fan 2. The fixed portion of the cover net 21 is fixedly connected to the center plate 11. The cover net 21 can prevent larger foreign objects in the surrounding environment from being sucked into the air duct and thereby blocking the air duct. In addition, the cover net 21 can also effectively protect the fan 2 and prevent hard objects from colliding with the fan 2, causing damage to the fan 2.

[0047] Furthermore, the windshield 3 abuts against the center plate 11 and the upper end surface of the housing, respectively, to form a spiral air duct. The condenser 43 is disposed within the spiral air duct, and the fan 2 is disposed near one end of the central portion of the spiral air duct and supplies air to the duct. The fan 2 draws in cooler air from the outside, which then travels from the inside out along the spiral air duct and briefly resides in the duct, exchanging heat with the condenser 43, thereby removing heat from the condenser 43.

[0048] As a preferred embodiment, the inflow portion 41 and the outflow portion 42 are arranged at the end of the air duct away from the fan 2, and the condensation duct 43 includes an inflow pipe 431 along the side of the air duct close to the fan 2 and an outflow pipe 432 along the side of the air duct away from the fan 2, one end of the inflow pipe 431 is connected to the inflow portion 41, the other end of the inflow pipe 431 extends along the air duct to the end of the air duct close to the fan 2 and then is connected to one end of the outflow pipe 432, and the other end of the outflow pipe 432 is connected to the outflow portion 42. This setting method can ensure that the entire part of the condensation duct 43 is in the air duct, so that it can efficiently exchange heat with the wind in the air duct, and arranging the condensation duct in a back-and-forth manner also helps to reduce the volume of the air duct.

[0049] Furthermore, the inflow pipe 431 abuts the center plate 11, and the outflow pipe 432 abuts the windshield 3 and the center plate 11. With this arrangement, the inflow pipe 431 can also dissipate heat via the center plate 11, while the outflow pipe 432 can dissipate heat via the windshield 3 and the center plate 11. While heat dissipation is achieved through air-cooled convection, heat conduction can also be achieved through the windshield 3, the center plate 11, and the like, further improving heat dissipation efficiency.

[0050] In another embodiment of the present invention, Figure 6As shown, the windshield 3 includes a plurality of windshield ribs 31 surrounding the fan 2 and arranged along the radial direction of the fan 2. The plurality of windshield ribs 31 respectively abut against the upper end surface of the housing and the center plate 11 to form a plurality of air ducts. The fan 2 is configured to supply air to one end of the plurality of air ducts close to the fan 2. In order to be able to blow air to different areas of the condenser 43 through each air duct, in this embodiment, the windshield 3 is configured to include at least four windshield ribs 31. These windshield ribs 31 respectively abut against the upper end surface of the housing and the center plate 11 to form a plurality of regional air ducts. The condenser 43 is fixedly connected to the center plate 11 around the windshield ribs 31. The fan 2 can blow air to different sections of the condenser 43 through the aforementioned regional air ducts, thereby achieving a good cooling effect.

[0051] Furthermore, the condenser 43 includes a plurality of U-shaped branch pipes 433, which are arranged around the wind shield rib 31, and one end of the plurality of U-shaped branch pipes 433 is connected to the inlet part 41, and the other end is connected to the outflow part 42. The condenser flows from the inlet part to the outflow part 42 through the plurality of U-shaped branch pipes 433 connected in parallel. During this process, each U-shaped branch pipe 433 can exchange heat with the wind blowing in the air duct, further improving the efficiency of cooling the condenser.

[0052] To better distribute the condensate to each U-shaped branch pipe 433, the inlet portion 41 is configured to include a first hollow cylindrical manifold 411. An inlet 4111 is provided on the sidewall of the first hollow cylindrical manifold 411 to accommodate the plurality of U-shaped branch pipes 433. The plurality of U-shaped branch pipes 433 communicate with the cavity of the first hollow cylindrical manifold 411 through the inlet 4111. A refrigerant inlet 4112 is also provided on the sidewall of the first hollow cylindrical manifold 411 opposite the inlet 4111. During operation, refrigerant flows through the refrigerant inlet 4112, collects in the first hollow cylindrical manifold 411, and is then evenly distributed to each U-shaped branch pipe 433 through the inlet 4111 on the sidewall of the first hollow cylindrical manifold 411.

[0053] Correspondingly, the outflow portion 42 includes a second hollow cylindrical manifold 421. An output port 4211 is provided on the sidewall of the second hollow cylindrical manifold 421, which cooperates with the multiple U-shaped branch pipes 433. The multiple U-shaped branch pipes 433 are connected to the cavity of the second hollow cylindrical manifold 421 through the output port 4211. A refrigerant outlet 4212 is also provided on the sidewall of the second hollow cylindrical manifold 421 opposite the output port 4211. This arrangement allows the refrigerant to flow out evenly through the refrigerant outlet 4212.

[0054] In summary, the refrigerator provided in this embodiment brings the following technical effects:

[0055] 1. Solve the problem of poor heat dissipation effect of the condenser of the refrigerator in the prior art;

[0056] 2. Setting the air duct into a spiral duct from the inside out helps the circulating air to be retained in the duct, thereby ensuring the effect of heat exchange;

[0057] 3. The inflow pipe is abutted against the center plate, and the outflow pipe is abutted against the windshield and the center plate. During the air-cooling heat exchange, the inflow pipe can also dissipate heat through the center plate, while the outflow pipe can dissipate heat through the center plate and the windshield, further improving the efficiency of heat exchange.

[0058] 4. Multiple air ducts are arranged along the radial direction of the fan. The air absorbed by the fan can be blown along these air ducts toward the multiple U-shaped branch pipes, thereby effectively cooling the U-shaped branch pipes.

[0059] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0060] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
