[0002] A refrigerator is a device for long-term preservation of food. It keeps food in a low-temperature state and ensures people's daily diet and health. It has become a very important electrical appliance in people's lives. With the continuous improvement of people's living standards, people tend to add ice cubes to drinks to lower the temperature of drinks in order to get a cool taste. The refrigerator itself creates an environment suitable for preserving food by lowering the temperature. The low temperature environment in the refrigerator is conducive to the production and storage of ice cubes, so the market demand for refrigerators with ice makers is gradually increasing.

[0003] The existing ice maker is mainly installed in the refrigeration chamber through a mounting frame, and the ice making grid is installed in the mounting frame.

[0048] The refrigerator 100 provided in the embodiment of the utility model can have various implementation forms. Figures 1 to 10 This is a specific implementation of the refrigerator 100 of the utility model. In this embodiment, the refrigerator 100 includes a box body 10, a door body 20 and an ice maker 30.

[0049] The directions described in the text are based on the direction in which the user faces the refrigerator 100, wherein the left and right sides are distinguished by the direction in which the user faces the refrigerator 100, the side facing the user when the refrigerator 100 is in use is defined as the front side, and the side opposite thereto is defined as the rear side, and the upper and lower sides of the refrigerator 100 when generally working normally are defined to distinguish the up and down.

[0050] like Figure 1 As shown, the box 10 is used to form the overall appearance of the refrigerator 100. The box 10 is roughly in the shape of a rectangular parallelepiped frame. The top of the box 10 and the bottom of the box 10 are opposite ends. From the top of the box 10 to the bottom of the box 10 is the height direction of the box 10. The left side of the box 10 and the right side of the box 10 are opposite sides. From the left side of the box 10 to the right side of the box 10 is the width direction of the box 10. The front side of the box 10 and the rear side of the box 10 are opposite sides. From the front side of the box 10 to the rear side of the box 10 is the thickness direction of the box 10; wherein, the first direction is the height direction of the box 10, and the second direction is the width direction of the box 10. The box 10 includes a box shell 11 and an inner liner 12. The inner liner 12 is arranged in the box shell 11, and an installation space is formed between the two, which is used to install other component structures of the refrigerator 100 and form a foam insulation layer. A refrigeration chamber 15 is provided inside the inner liner 12. The refrigeration chamber 15 is used to place goods. The refrigeration chamber 15 has a chamber opening, and the chamber opening is arranged toward the front side of the box body 10. The refrigeration chamber 15 can be a refrigerated temperature environment, a frozen temperature environment, or a normal temperature environment.

[0051] Furthermore, a door 20 (not shown) is provided at the opening of the chamber. The door 20 is arranged at the front side of the box body 10 in a straight plate shape, and the door 20 is connected to the box body 10 in an openable and closable manner to open or close the refrigeration chamber 15.

[0052] It can be understood that the refrigerator 100 also includes a refrigeration system (not shown) and an air supply system (not shown), and the refrigeration system and the air supply system are electrically connected to a power supply component, and the power supply component is used to supply electricity to each component of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0053] The refrigeration system is installed in the box 10, and the refrigeration system is used to provide cold air to the refrigeration chamber 15. The refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device, and a refrigerant. Each component is distributed at different positions of the box 10 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process. The compression process is: after the power cord of the refrigerator 100 is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor of normal temperature and high pressure, and is cooled to a saturated refrigerant liquid. The throttling process is as follows: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device, where it is throttled and depressurized, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which lowers the temperature of the evaporator and its surroundings, achieving refrigeration, and turning the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor, and the above process is repeated. Energy conversion is performed through the change in the state of the refrigerant, and the heat in the refrigerator 100 is transferred to the air outside the box, thereby achieving the refrigeration cycle of the refrigerator 100.

[0054] The air supply system is installed in the box 10 to provide power for the flow of cold air; the air supply system generally includes a fan and an air supply duct defined in the box 10. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box 10 is also defined to form an air duct cavity, which is connected to the air supply duct and the refrigeration chamber 15 respectively, so that the air supply duct is connected to the refrigeration chamber 15 through the air duct cavity; it should be noted that the inner liner 12 is provided with an air outlet, which is used to connect the air duct cavity and the refrigeration chamber 15. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the refrigeration chamber 15 to cool the refrigeration chamber 15. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall of the inner liner 12 on the side opposite to the opening of the refrigeration chamber 15 or on the side wall of the inner liner 12 on the side adjacent to the opening of the refrigeration chamber 15; it should also be noted that the refrigeration system and the air supply system belong to common knowledge in the field and will not be described in detail here.

[0055] In the refrigerator 100, if Figures 1 to 10 As shown, the ice maker 30 is arranged in the refrigeration chamber 15, and the ice maker 30 is configured to produce ice cubes. The ice maker 30 includes a mounting frame 31, an ice making grid 32 and a water injection pipe 33. The mounting frame 31 is connected to the inner tank 12, and a water injection hole 311 is arranged on the mounting frame 31; the ice making grid 32 is installed in the mounting frame 31; the water injection pipe 33 is provided with a water outlet end, and the water outlet end of the water injection pipe 33 is arranged corresponding to the water injection hole 311, and the water injection pipe 33 injects water into the ice making grid 32 through the water injection hole 311. Among them, an overflow cover 315 is arranged on the mounting frame 31; the overflow cover 315 is arranged at the periphery of the water injection hole 311, and the overflow cover 315 is arranged on the outer side of the water outlet end, and the overflow cover 315 is used to guide the water flow of the water injection pipe 33 to inject water into the ice making grid 32. By setting up the overflow cover 315, all the water discharged from the water outlet is introduced into the ice making grid 32. At the same time, the splashing water droplets are blocked by the overflow cover 315 to prevent water from splashing onto the mounting frame 31, thereby preventing the mounting frame 31 from being blocked by the water injection hole 311 due to ice formation, thereby ensuring the water injection efficiency and stability.

[0056] Furthermore, the ice maker 30 is installed on the inner tank 12, and the refrigeration chamber 15 is in a freezing temperature environment, and then the low temperature environment of the refrigeration chamber 15 is used to condense the water in the ice cubes 32 into ice cubes. In another embodiment, the ice maker 30 can also be installed on the door body 20. The ice maker 30 installed on the door body 20 can take out the ice cubes in the ice maker 30 without opening the door body 20, which is more convenient to use and improves the user experience. In another embodiment, the ice maker 30 can also be set in the refrigeration chamber 15 of the refrigeration temperature environment or the normal temperature environment. At this time, the water in the ice cubes 32 cannot be condensed into ice by relying on the temperature environment in the refrigeration chamber 15, so it is necessary to install a condenser on the ice cubes 32, and the temperature of the ice cubes 32 is reduced by the condenser, so that the water in the ice cubes 32 is condensed into ice.

[0057] Furthermore, a plurality of ice makers 30 may be provided, and each ice maker 30 is sequentially arranged on the inner tank 12 to improve ice making efficiency and ice making amount.

[0058] Furthermore, the mounting frame 31 is hoisted in the refrigeration chamber 15. The mounting frame 31 is roughly in the shape of a hollow rectangle. The opening direction of the mounting frame 31 faces downward to facilitate the discharge of ice cubes. The ice cubes fall into the ice storage box (not shown) below the mounting frame 31 under their own gravity for unified collection. In this embodiment, the ice maker 30 also includes an end cover 34. The end cover 34 is roughly in the shape of a straight plate. The end cover 34 is arranged between the inner liner 12 and the mounting frame 31. The end cover 34 is connected and fixed to the inner liner 12. The mounting frame 31 is detachably connected to the end cover 34. The mounting frame 31 is hoisted in the refrigeration chamber 15 through the end cover 34. The end cover 34 is a bearing component of the ice maker 30. During the assembly process, the end cover 34 is connected to the inner tank 12, and then the end cover 34 is fixed at a specified position of the inner tank 12 through a foaming process, and then the mounting frame 31 of the ice maker 30 is detachably hoisted on the end cover 34, so that the ice maker 30 can be installed in the refrigeration chamber 15.

[0059] Furthermore, the ice making grid 32 is arranged in the mounting frame 31, and the ice making grid 32 is rotatably connected to the mounting frame 31. After the water in the ice making grid 32 condenses into ice cubes, the ice cubes are freely dropped into the ice storage box below for collection by rotating the ice making grid 32. In this embodiment, the water injection hole 311 of the mounting frame 31 is roughly rectangular, and the water injection hole 311 is arranged at the top of the mounting frame 31, so that water flows from top to bottom into the ice making grid 32, and the water injection efficiency is higher.

[0060] Furthermore, the overflow cover 315 is roughly U-shaped, and is disposed at the periphery of the water injection hole 311. The opening direction of the overflow cover 315 faces the water injection pipe 33 to ensure that the water discharged from the water injection pipe 33 contacts the overflow cover 315, and is all guided by the overflow cover 315 into the ice making tray 32 below. In this embodiment, the overflow cover 315 includes a side plate 3151 and a connecting plate 3152. The side panels 3151 are relatively arranged on both sides of the water injection pipe 33, and the connecting plate 3152 is arranged between the side panels 3151 on both sides. The connecting plate 3152 is arranged on the side of the water injection hole 311 away from the water injection pipe 33. The connecting plate 3152 is mainly in contact with the water flow discharged from the water injection pipe 33. The connecting plate 3152 is used to guide the water flow into the ice making grid 32. The side panels 3151 on both sides of the connecting plate 3152 are used to block the splashing water during the contact between the connecting plate 3152 and the water flow, so as to prevent water from splashing onto the mounting frame 31.

[0061] Further, the connecting plate 3152 includes a first guide portion 3155 and a second guide portion 3156. The first guide portion 3155 is in the shape of a straight plate, and the first guide portion 3155 is connected to the mounting frame 31. The first guide portion 3155 extends obliquely from the mounting frame 31 to the water injection pipe 33 in a shape gradually approaching the inside of the water injection hole 311. The second guide portion 3156 is in the shape of a straight plate, and the second guide portion 3156 is arranged on a side of the first guide portion 3155 away from the mounting frame 31. The second guide portion 3156 extends obliquely from the first guide portion 3155 to the inside of the water injection hole 311 in a shape gradually away from the water injection pipe 33. In this embodiment, the water injection pipe 33 is in the shape of a straight pipe, and the angle between the central axis of the water injection pipe 33 and the first guide portion 3155 is greater than the angle between the central axis of the water injection pipe 33 and the second guide portion 3156. By setting a larger angle between the first guide part 3155 and the water injection pipe 33, the impulse of the water flow itself is reduced as much as possible after the water flow contacts the first guide part 3155, thereby improving the guiding effect of the first guide part 3155 on the water flow; by setting a smaller angle between the second guide part 3156 and the water injection pipe 33, the gap between the second guide part 3156 and the water injection pipe 33 is reduced, thereby improving the blocking effect on splashing water.

[0062] Furthermore, the water injection pipe 33 includes an inner pipe 331 and an outer pipe 332. The inner pipe 331 is in the shape of a hollow circular tube, and the water outlet is arranged on the inner pipe 331. The inner pipe 331 is used to inject water into the ice making grid 32. The outer pipe 332 is in the shape of a hollow circular tube, and the outer pipe 332 is arranged around the outer side of the inner pipe 331. A gap is arranged between the outer pipe 332 and the inner pipe 331 to reduce the heat conduction efficiency of the water injection pipe 33, and to prevent the water from being blocked by ice due to the low temperature environment during the flow of the water in the inner pipe 331.

[0063] Furthermore, the water injection pipe 33 also includes a heating element 333. The heating element 333 is annular and is disposed between the inner tube 331 and the outer tube 332. The heating element 333 is used to heat the inner tube 331, thereby preventing the water flow from freezing in the inner tube 331 and ensuring the stability of the inner tube 331 injecting water into the ice making grid 32. In this embodiment, the outer tube 332 is connected to the end cover 34, and the inner tube 331 and the heating element 333 pass through the end cover 34 and extend toward the water injection hole 311. By passing the inner tube 331 through the end cover 34, it is ensured that the inner tube 331 injects water into the ice making grid 32. By passing the heating element 333 through the end cover 34, it is ensured that the heating element 333 is at least partially disposed between the end cover 34 and the mounting frame 31, and then the heat generated by the heating element 333 is transferred to the overflow cover 315, thereby preventing the water flow from freezing at the overflow cover 315 and improving the stability of water injection.

[0064] The utility model also discloses a refrigerator 100, comprising a box body 10, a door body 20 and an ice maker 30. The box body 10 comprises a box shell 11 and an inner liner 12, the inner liner 12 is arranged in the box shell 11, and a refrigeration chamber 15 is arranged inside the inner liner 12. The door body 20 is connected to the box body 10 to open or close the refrigeration chamber 15. The ice maker 30 is arranged in the refrigeration chamber 15; the ice maker 30 comprises a mounting frame 31, an ice making grid 32 and a water injection pipe 33; the mounting frame 31 is connected to the inner liner 12, and a water injection hole 311 is arranged on the mounting frame 31; the ice making grid 32 is installed in the mounting frame 31; the water injection pipe 33 is provided with a water outlet end, the water outlet end of the water injection pipe 33 is arranged corresponding to the water injection hole 311, and the water injection pipe 33 injects water into the ice making grid 32 through the water injection hole 311. Among them, the mounting frame 31 is provided with an overflow cover 315; the overflow cover 315 is arranged at the periphery of the water injection hole 311, and the corresponding cover of the overflow cover 315 is arranged on the outside of the water outlet end, and the overflow cover 315 and the mounting frame 31 are an integral part. By setting the overflow cover 315 and the mounting frame 31 as an integral part, it is only necessary to fix the mounting frame 31 during installation, thereby improving the assembly efficiency. At the same time, setting the overflow cover 315 and the mounting frame 31 as an integral part can prevent water from leaking from the joint position of the overflow cover 315 and the mounting frame 31, thereby preventing the mounting frame 31 from freezing due to water seepage. In addition, setting the overflow cover 315 and the mounting frame 31 as an integral part can also effectively improve the bearing strength between the overflow cover 315 and the mounting frame 31, and improve the reliability of water flow guidance and water splash prevention.

[0065] In summary, the embodiment of the utility model provides a refrigerator 100, which has the following beneficial effects:

[0066] By arranging an overflow cover 315 at the periphery of the water injection hole 311, the overflow cover 315 is arranged on the outer side of the water outlet end, and the overflow cover 315 guides the water flow of the injected water, so as to guide the water flow into the ice making grid 32 and block the splashing water, so as to avoid the water splashing onto the mounting frame 31 during the process of being injected into the ice making grid 32 by the water injection pipe 33, thereby eliminating the problem of freezing of the mounting frame 31 and ensuring the water injection efficiency and water injection stability.

[0067] The connecting plate 3152 of the overflow cover 315 includes a first guide portion 3155 and a second guide portion 3156. The angle between the first guide portion 3155 and the water injection pipe 33 is greater than the angle between the second guide portion 3156 and the water injection pipe 33. The first guide portion 3155 guides the water flow at a larger angle to reduce the impulse of the water flow and ensure that the water flow is better introduced into the ice cube tray 32. At the same time, by setting a smaller angle between the second guide portion 3156 and the water injection pipe 33, the gap between the overflow cover 315 and the water injection pipe 33 is reduced, so that the splashing water can be effectively blocked, thereby improving the blocking effect of the overflow cover 315 on the splashing water.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
