[0002] With the increasing use of refrigerators in our daily lives, they have not only improved the freshness of food in the kitchen but also enhanced our quality of life. At the same time, with economic development, people's demand for refrigerator capacity is increasing, and their user experience is also improving. Built-in refrigerators are becoming increasingly popular in the market. Built-in refrigerators can be embedded in cabinets, making the cabinets and refrigerators more beautiful and simple as a whole. However, due to the embedded installation of the refrigerator, the gap between its left and right side panels and back and the cabinet or wall becomes smaller and more closed. Heat from the sides and / or back of the refrigerator cannot be transferred away, resulting in an increase in the air temperature near the refrigerator side panels. The corresponding heat exchange temperature difference between the condenser and the external environment becomes smaller, and the heat dissipated by the condenser cannot be effectively transferred outward, resulting in poor condenser heat dissipation and affecting refrigerator performance.

[0003] In order to meet the heat dissipation requirements of built-in refrigerators, a fan is installed in the compressor compartment to dissipate heat from the condenser. However, the fan disturbs the air, causing dust to rise. Over time, the condenser will be covered with dust, affecting the heat dissipation efficiency of the condenser and causing poor working efficiency of the built-in refrigerator. Summary of the Invention

[0004] In order to solve the technical problem in the prior art that the condenser is covered with dust, which affects the heat dissipation efficiency of the condenser and the working efficiency of the refrigerator, a refrigerator is provided that uses an atomizing structure to spray into the compressor cavity to dissipate heat from the compressor cavity and clean the heat exchanger to achieve the purpose of self-cleaning and improve working efficiency.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "installed," "disposed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] In order to meet the heat dissipation requirements of built-in refrigerators, a fan is installed in the compressor compartment to dissipate heat from the condenser. However, the fan disturbs the air, causing dust to rise. Over time, the condenser will be covered with dust, affecting the heat dissipation efficiency of the condenser and causing poor working efficiency of the built-in refrigerator.

[0036] To this end, this application provides a Figures 1 to 6The refrigerator shown includes: a cabinet 1, in which a compression chamber 11 is formed; a heat exchanger 2, which is arranged in the compression chamber 11; a door body 3, which is movably arranged on the cabinet 1, and the door body 3 can open or close the cabinet 1; an atomizing structure, which is arranged in the cabinet 1, and the movement of the door body 3 can drive the atomizing structure to spray toward the compression chamber 11 to cool the compression chamber 11 and clean the heat exchanger 2. By utilizing an atomizing structure to spray into the compressor cavity, water mist is utilized to dissipate heat from the compressor cavity, thereby satisfying the heat dissipation requirements of the refrigerator. Simultaneously, the water mist can also be sprayed onto the heat exchanger 2 to clean the attachments on the surface of the heat exchanger 2, thereby enhancing the heat dissipation capability of the heat exchanger 2 and improving the working efficiency of the refrigerator. Furthermore, by utilizing the movement of the door 3 to drive the atomizing structure, the energy consumption of the refrigerator can be kept constant. In particular, when the door 3 is opened, the refrigerator compressor generates heat in the compressor cavity while operating. At this time, spraying the compressor cavity can rapidly dissipate the heat, thereby preventing heat from accumulating in the compressor cavity and requiring the refrigerator to continuously dissipate heat. This further improves the working efficiency of the refrigerator and reduces its energy consumption, while achieving the goals of resource conservation and resource recycling. Preferably, the heat exchanger 2 is a condenser.

[0037] When the refrigerator is operating normally, the door 3 seals the cabinet 1, and the refrigerator's compressor and fan work according to the preset program in the refrigerator. When the compressor is working, the compressor and heat exchanger 2 will release heat in the compressor cavity, and the fan needs to drive the gas to flow through the compressor cavity to dissipate heat. When taking or storing items from the cabinet 1, the user needs to open the door 3. At this time, the door 3 will be moved by the user, and the atomizing structure can use the movement of the door 3 as a power source to work, thereby achieving the purpose of spraying into the compressor cavity without consuming energy. Since the door 3 is opened, the cold air in the cabinet 1 will be released into the room. At this time, the compressor needs to work to maintain the temperature in the cabinet 1, and the compressor will generate heat in the compressor cavity. The spray of the atomizing structure can offset this part of the heat, reducing the temperature rise of the compressor cavity, thereby reducing the energy consumed by the refrigerator to dissipate this part of the heat, thereby reducing the energy consumption of the refrigerator. At the same time, users basically operate the refrigerator every day. Each time the door body 3 moves, the atomizing structure can spray toward the heat exchanger 2. That is, the refrigerator can basically clean the heat exchanger 2 every day, thereby avoiding the long-term accumulation of dust that is difficult to remove, ensuring the cleanliness of the heat exchanger 2 and the heat exchange efficiency, and effectively improving the working efficiency of the refrigerator.

[0038] To further reduce the refrigerator's energy consumption and structural complexity, the refrigerator also includes a water tray 4, which is disposed within the housing 1 and communicates with the water inlet of the atomizing structure. The water tray 4 is used to collect defrost water from the refrigerator's evaporator. This defrost water is a clean source and can be directly supplied to the atomizing structure without requiring the refrigerator to draw water from an external source. This reduces the refrigerator's structural complexity and energy consumption, while also conserving and recycling resources.

[0039] The atomizing structure includes: an atomizing nozzle 51, the spray direction of which is directed toward the compression chamber 11, the water inlet of which is connected to the water receiving pan 4; and a compression assembly connected to the door body 3, the compressed gas outlet of which is connected to the gas inlet of the atomizing nozzle 51. The compression assembly provides pressurized gas to the atomizing nozzle 51. When the pressurized gas passes through the water inlet of the atomizing nozzle 51, it can entrain the water in the water inlet and be sprayed out through the atomizing nozzle 51 to form a water mist, thereby achieving the effect of spraying the compressor chamber and the heat exchanger 2.

[0040] As an embodiment, the compression assembly includes a cylinder 52 and a piston. The piston is movably disposed in the cylinder 52. The cylinder 52 is provided with the compressed gas outlet. The piston is connected to the door body 3. The movement of the door body 3 can drive the piston to move in the cylinder 52. The movement of the door body 3 can drive the piston to move, thereby compressing the gas in the cylinder 52. Finally, the compressed gas can be delivered to the atomizing nozzle 51 through the compressed gas outlet.

[0041] The compression assembly further includes a speed change mechanism, through which the piston is connected to the door body 3. The speed change mechanism amplifies the moving force of the door body 3, so that the user can drive the piston to move by operating the door body 3 with less force, thereby improving the user experience.

[0042] Specifically, the speed change mechanism includes a driving gear 53, a driven gear 54, and a rack 55. The door body 3 has a rotating shaft, the driving gear 53 is arranged on the rotating shaft, the driven gear 54 is meshed with or transmits with the driving gear 53, the rack 55 is connected to the piston, and the rack 55 and the driven gear 54 are meshed with each other. The door body 3 is rotatably arranged on the box body 1 via the rotating shaft. When the user needs to open the door body 3, the door body 3 can be driven to rotate, the driving gear 53 rotates with the rotation of the door body 3, and the driven gear 54 can rotate with the rotation of the driving gear 53. The rotation of the driven gear 54 can drive the rack 55 to move linearly, and the linear movement of the rack 55 can drive the piston to move linearly, thereby achieving the purpose of the piston moving in the cylinder 52 to compress the gas. By utilizing the transmission ratio between the driving gear 53 and the driven gear 54, the purpose of speed change is achieved, and the purpose of amplifying the torque of the door body 3 is also achieved. The user can drive the piston to move by operating the door body 3 with less force, thereby improving the user experience.

[0043] Furthermore, the compression assembly further includes a belt, which is looped around the driving gear 53 and the driven gear 54. The driving gear 53 drives the driven gear 54 via the belt. By using the belt to simultaneously mesh with the driving gear 53 and the driven gear 54, the transmission ratio between the driving gear 53 and the driven gear 54 can be further amplified, further reducing the driving force applied by the user to the door body 3 and improving the user experience.

[0044] like Figure 2 As shown, the compression assembly also includes an intermediate gear, which has a coaxially arranged small gear and a large gear. The driving gear 53 is connected to the small gear through a belt, and the large gear is connected to the driven gear 54 through another belt. The driving gear 53 drives the small gear to rotate. Since the small gear and the large gear are coaxially arranged, the large gear rotates synchronously at this time and drives the driven gear 54 to rotate. Further, the transmission ratio between the driving gear 53 and the driven gear 54 is such that the user can drive the piston to move by operating the door body 3 with less force, thereby improving the user experience.

[0045] Preferably, the length of the rack 55 is parallel to the direction of movement of the piston. The driven gear 54 drives the rack 55 to move along its length, thereby driving the piston to move in a set direction, ensuring reliable movement of the piston. A connecting member is provided between the rack 55 and the piston to ensure reliable synchronous movement of the rack 55 and the piston.

[0046] Cylinder 52 is provided with an air inlet, which is equipped with a one-way valve. The direction of the one-way valve is from the outside of cylinder 52 to the inside of cylinder 52. The air inlet allows gas to enter cylinder 52 from the outside, providing a gas source for piston compression. The one-way valve ensures that gas does not exit cylinder 52 through the air inlet during the piston compression process, ensuring reliable piston compression. The air inlet is connected to the outside of the refrigerator body 1, directly drawing gas from the refrigerator space. This process does not consume the cold air within the refrigerator body 1, further reducing the refrigerator's energy consumption.

[0047] A two-way valve is provided at the compressed gas outlet. The two-way valve can remain closed during the piston compression process and the air intake process of the cylinder 52, and open after the piston completes the compression, so that the compressed gas is sent to the atomizing nozzle 51 through the compressed gas outlet for use, thereby ensuring the working reliability of the compression component.

[0048] The compression assembly is arranged on the top of the box body 1. This reduces the space occupied by the compression assembly in the refrigerator, improves the use effect of the refrigerator, and can also facilitate the connection between the compression assembly and the door body 3, thereby improving the structural reliability of the refrigerator.

[0049] Since the compressor chamber of the refrigerator is generally arranged at the bottom of the box body 1, the refrigerator also includes an air pipe 56, one end of the air pipe 56 is connected to the compressed gas outlet of the compression assembly, and the other end is connected to the gas inlet of the atomizing nozzle 51. The air pipe 56 can be arranged in the foaming layer of the box body 1 to avoid the air pipe 56 occupying the internal space of the box body 1, thereby improving the use effect of the refrigerator.

[0050] The housing 1 is provided with a heat dissipation hole, and the heat exchanger 2 is located on one side of the heat dissipation hole. There are at least two atomizing nozzles 51, and all of the atomizing nozzles 51 are arranged in sequence in a direction away from the heat dissipation hole. The refrigerator uses the heat dissipation hole to dissipate heat from the compressor cavity. At this time, the portion of the heat exchanger 2 near the heat dissipation hole is most likely to accumulate dust. Although other positions of the heat exchanger 2 are farther from the heat dissipation hole, the heat exchanger 2 as a whole is closer to the heat dissipation hole, resulting in the accumulation of attachments on the entire surface of the heat exchanger 2. Therefore, the atomizing nozzles 51 are preferentially arranged in the portion near the heat dissipation hole to ensure the cleaning effect of this portion of the heat exchanger 2. At the same time, other atomizing nozzles 51 are used to spray and clean other portions of the heat exchanger 2 to ensure the overall cleaning effect of the heat exchanger 2. In addition, multiple atomizing nozzles 51 can further increase the distribution of water mist in the compressor cavity, thereby increasing the cooling effect on the compressor cavity and improving the operating efficiency of the refrigerator.

[0051] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
