Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration and freezing, in particular to a refrigerator. Background Art

[0002] As living standards continue to improve, refrigerators, as a necessity for modern families, are also expanding and improving their functions. Refrigerators can not only use refrigeration to keep their internal low temperature to preserve food, but also have the function of making ice cubes directly inside for users to use.

[0003] In existing refrigerator designs, in order to meet users' demand for ice cubes, a dedicated ice-making compartment is usually set up in the refrigerator door of the refrigerator. The refrigerator compartment is equipped with a separate evaporator to provide cold air for the refrigerator compartment and the ice-making compartment. However, this evaporator is usually installed at the rear side of the refrigerator compartment. Although it can ensure good heat exchange between the evaporator and the ice-making compartment, it also brings a series of problems.

[0004] First, placing the evaporator at the back of the refrigerator compartment will occupy a portion of the depth of the refrigerator, thereby limiting the storage capacity of the refrigerator compartment. For shorter users, it is extremely inconvenient to take items from the top layer of the refrigerator compartment.

[0005] Secondly, since the evaporator is located at the back of the cold storage room, the cold air it generates needs to circulate inside the cold storage room before it can reach every corner of the cold storage room. This process often leads to uneven distribution of cold air, especially when there are many items placed inside the cold storage room, which can easily cause the temperature in some areas to be too high or too low, affecting the cooling effect of the cold storage room.

[0006] Therefore, in view of the problems existing in the existing refrigerator design, a new refrigerator design is needed, which can reduce the impact of the evaporator on the storage space of the refrigerator compartment while ensuring the ice-making effect and improve the uniformity of cold air distribution in the refrigerator compartment. Utility Model Content

[0007] One purpose of the utility model is to reasonably arrange the position of the evaporator to ensure the ice-making effect of the ice-making compartment and facilitate users to take items in the storage compartment.

[0008] A further object of the present invention is to improve the refrigeration effect of the storage room and ensure that the cold air in the storage room is evenly distributed.

[0009] Another further object of the utility model is to ensure that the condensed water produced by the evaporator can be discharged in time to maintain the dryness and cleanliness of the cooling chamber.

[0010] In particular, the utility model provides a refrigerator, comprising:

[0018] Optionally, a partition plate is provided in the cooling chamber, and the partition plate extends forward from the evaporator to between the ice-making air supply port and the ice-making air return port.

[0019] Optionally, the fan is arranged in the cooling chamber below the ice-making air supply outlet, the storage air supply outlet is located on an air supply path between the fan and the ice-making air supply outlet, and the storage return air outlet is located behind the ice-making return air outlet.

[0020] Optionally, the front edge of the storage air supply port is provided with wind shielding ribs extending upward.

[0021] Optionally, the cabinet door is a double-door, including a first door body and a second door body, the interiors of the first door body and the second door body both define the ice-making compartment, and the two ice-making compartments have respective ice-making air supply ports and ice-making air return ports.

[0022] Optionally, the projections of the two ice-making air supply ports on the rear side of the cooling chamber fall on the evaporator; and

[0023] The projections of the two ice-making return air ports on the rear side of the cooling chamber fall on both sides of the evaporator.

[0024] Optionally, the cooling chamber has a first bottom wall and a second bottom wall extending gradually downward from both lateral sides to the middle; and the first bottom wall and the second bottom wall are both inclined downward from front to back, so that their respective front sides are higher than the rear sides.

[0025] Optionally, a drain outlet is provided in the cooling chamber, the drain outlet is located behind the evaporator and is connected to a drain pipe extending downward.

[0026] The refrigerator of the utility model has a cooling chamber located above the storage compartment, and the evaporator can be arranged in the cooling chamber without occupying the rear space of the storage compartment, which is conducive to increasing the storage capacity of the storage compartment in the depth direction, making more effective use of the internal space of the storage compartment, and also facilitating users with shorter stature to take and put items. An ice-making chamber is defined in the door of the refrigerator, and the cold air produced by the evaporator in the cooling chamber can be transported to the storage compartment and the ice-making chamber by the fan, which not only ensures the fresh-keeping effect of the storage compartment, but also ensures the ice-making effect of the ice-making chamber, which is conducive to the formation and storage of ice cubes.

[0027] Furthermore, in the refrigerator of the utility model, the ice-making air supply port is formed at the front side of the cooling chamber, and the ice-making chamber can directly receive the cold air from the cooling chamber, which is conducive to shortening the air supply path and reducing the cold loss, thereby ensuring the ice-making effect and reducing the energy consumption of ice-making. At the same time, the storage air supply port is located at the bottom of the cooling chamber, and the cold air in the cooling chamber can be evenly sunk to the storage chamber through the storage air supply port, so that the cold air is more evenly distributed in the storage chamber, avoiding the problem of local overcooling or overheating in the storage chamber, and ensuring the refrigeration effect of the items in the storage chamber.

[0028] Furthermore, the refrigerator of the utility model is provided with a drain port in the cooling chamber, which is located behind the evaporator and connected to a drain pipe extending downward. The condensed water generated by the evaporator during the refrigeration process can flow into the drain pipe through the drain port and be discharged outward along the drain pipe in a timely manner, thereby preventing the condensed water from accumulating in the cooling chamber, causing excessive humidity in the cooling chamber, and even causing bacteria to grow. In this way, the dryness and cleanliness of the cooling chamber are maintained, and the cooling chamber is prevented from breeding bacteria and contaminating the items in the storage room and the ice cubes in the ice making room.

[0041] Figure 1 is a schematic structural diagram of a refrigerator 10 according to an embodiment of the utility model. Figure 2 is a schematic structural diagram of a storage compartment 110 according to an embodiment of the utility model. Figure 3 is a schematic structural diagram of a cooling chamber 210 according to an embodiment of the present utility model. Figure 4 is a schematic top view of a housing 20 according to an embodiment of the present utility model. Figure 5 is a schematic side view of a housing 20 according to an embodiment of the present utility model. Figure 6 It is a schematic diagram of the air supply state of the refrigerator 10 according to one embodiment of the utility model.

[0042] The utility model provides a refrigerator 10, which may include a housing 11, a door 12, an evaporator 13 and a fan 14. The housing 11 defines a cooling chamber 210 and a storage compartment 110, and the cooling chamber 210 is located above the storage compartment 110. The door 12 is pivotally connected to the housing 11 for opening and closing the storage compartment 110, and an ice-making compartment 120 is defined in the door 12. The evaporator 13 is arranged in the cooling chamber 210 for producing cold air, and the fan 14 is arranged in the cooling chamber 210 for blowing the cold air produced by the evaporator 13 to the storage compartment 110 and the ice-making compartment 120, respectively.

[0043] In the refrigerator 10 of the present invention, since the cooling chamber 210 is located above the storage compartment 110, the evaporator 13 can be arranged in the cooling chamber 210 without occupying the rear space of the storage compartment 110, which is conducive to improving the storage capacity of the storage compartment 110 in the depth direction, making more effective use of the internal space of the storage compartment 110, and also making it convenient for users with shorter stature to take and put items.

[0044] An ice-making compartment 120 is defined in the door 12 of the refrigerator 10. The cold air produced by the evaporator 13 in the cooling chamber 210 can be transported by the fan 14 to the storage compartment 110 and the ice-making compartment 120, respectively, which not only ensures the freshness preservation effect of the storage compartment 110, but also ensures the ice-making effect of the ice-making compartment 120, which is conducive to the formation and storage of ice cubes.

[0045] In this embodiment, the number of the storage compartments 110 in the box body 11 is allowed to be one or more, for example, two. The two storage compartments 110 are arranged up and down, and the upper storage compartment 110 can be configured as a refrigerating compartment, and the lower storage compartment 110 can be configured as a freezing compartment.

[0046] When there are multiple storage compartments 110, the cooling compartment 210 should be located above all the storage compartments 110. Here, "above" means that the cooling compartment 210 should be located above the inside or outside of the highest storage compartment 110. For example, the refrigerating compartment and the freezing compartment are arranged up and down, and the cooling compartment 210 is located above the inside of the refrigerating compartment. For another example, the cooling compartment 210, the refrigerating compartment, and the freezing compartment are arranged in order from top to bottom.

[0047] Figure 2 The storage compartment 110 shown in the figure may be a refrigerating compartment, and the cooling chamber 210 is arranged above the interior of the refrigerating compartment. For the convenience of display, the door 12 (refrigerating chamber door 12) is hidden in the figure. The cold air in the refrigerating compartment and the ice making compartment 120 is provided by the evaporator 13 in the cooling chamber 210. When a freezing compartment is arranged below the refrigerating compartment, the cold air in the freezing compartment is provided separately by the freezing evaporator in the refrigeration system of the refrigerator 10.

[0048] like Figure 3 As shown, an ice-making air supply port 211 and an ice-making air return port 212 are provided at the front side of the cooling chamber 210, which are connected to the ice-making chamber 120. The ice-making air supply port 211 is provided at the front side of the cooling chamber 210, so that the ice-making chamber 120 can directly receive cold air from the cooling chamber 210, which is conducive to shortening the air supply path and reducing the loss of cold air, thereby ensuring the ice-making effect and reducing the energy consumption of ice-making.

[0049] The bottom of the cooling chamber 210 is provided with a storage air supply port 213 and a storage air return port 214 connected to the storage compartment 110. The storage air supply port 213 is provided at the bottom of the cooling chamber 210, so that the cold air in the cooling chamber 210 can directly sink to the storage compartment 110 and be evenly distributed in the storage compartment 110, thereby avoiding the problem of partial overcooling or overheating in the storage compartment 110 and ensuring the refrigeration effect of the items in the storage compartment 110.

[0050] The evaporator 13 can be installed horizontally in the cooling chamber 210. On the one hand, the evaporator 13 installed horizontally can increase its contact area with the air in the cooling chamber 210, thereby absorbing heat more effectively and improving the refrigeration efficiency. On the other hand, the evaporator 13 installed horizontally can reduce the vibration between the fan 14 and the evaporator 13, thereby reducing the noise during the operation of the refrigerator 10. On the other hand, the evaporator 13 installed horizontally can make the cold air more evenly distributed in the cooling chamber 210, which is convenient for designing the air supply path.

[0051] In an optional embodiment, the evaporator 13 is installed horizontally at the rear side of the cooling chamber 210, the ice-making air supply port 211 and the ice-making air return port 212 are arranged at the front side of the cooling chamber 210 at intervals, and the fan 14 is located between the evaporator 13 and the ice-making air supply port 211 and faces the ice-making air supply port 211. In this way, the fan 14 can supply air directly to the ice-making air supply port 211 during operation, which can ensure that the ice-making chamber 120 is adequately supplied with cold air, and the cold air forms an effective circulation in the ice-making chamber 120 to avoid airflow dead corners.

[0052] Furthermore, a partition plate 206 is provided in the cooling chamber 210, and the partition plate 206 extends forward from the evaporator 13 to between the ice-making air supply port 211 and the ice-making air return port 212. In this way, the airflow direction in the cooling chamber 210 can be effectively controlled by means of the partition plate 206, ensuring that the cold air enters the ice-making chamber 120 through the ice-making air supply port 211, while preventing the cold air from directly flowing back from the ice-making air return port 212, reducing the ineffective circulation of the cold air in the cooling chamber 210, and improving the ice-making efficiency.

[0053] The fan 14 may be arranged in the cooling chamber 210 below the ice-making air outlet 211. Since the fan 14 is located at a lower position, the cold air from the evaporator 13 may be more effectively sucked in and directed to the ice-making area through the ice-making air outlet 211. The lower position of the fan 14 may reduce the rise and dispersion of the cold air, thereby improving the refrigeration efficiency.

[0054] The storage air supply port 213 may be located on the air supply path of the fan 14 and the ice-making air supply port 211. This means that part of the cold air blown out from the fan 14 will pass through the storage air supply port 213 and enter the storage compartment 110, thereby providing cooling for the items in the storage compartment 110. The storage return air port 214 may be located behind the ice-making return air port 212. This means that the air from the storage compartment 110 can flow back to the cooling compartment through the storage return air port 214, and be sucked into the fan 14 again through the evaporator 13 and recycled, forming a circulating air flow system.

[0055] Considering that the storage compartment 110 has a larger space, its cooling demand is often greater than that of the ice-making compartment 120 , and the fan 14 is arranged toward the ice-making air outlet 211 , resulting in most of the cold air being blown to the ice-making compartment 120 during the air supply process.

[0056] In an optional embodiment, the front edge of the storage air supply port 213 is provided with an upwardly extending wind shield rib 207. The height of the wind shield rib 207 can be 2 mm to 10 mm, for example, 2 mm, 3 mm, 5 mm, 10 mm, etc.

[0057] During the air supply process, when the cold air delivered by the fan 14 flows through the storage air supply port 213, the wind shield 207 blocks part of the cold air and changes its flow direction. The blocked cold air then flows downward into the storage compartment 110 along the guidance of the wind shield 207. In this way, more cold air can be directed to the storage compartment 110 with a greater cooling demand, thereby maintaining a constant internal temperature of the storage compartment 110.

[0058] In another embodiment, a storage air door is provided at the storage air supply port 213 , and an ice-making air door is provided at the ice-making air supply port 211 .

[0059] The storage air door and the ice making air door can be selectively opened or closed. In this way, cold air can be blown only to the ice making compartment 120 or only to the storage compartment 110, realizing the independent refrigeration of the storage compartment 110 and the ice making compartment 120.

[0060] In an optional embodiment, the door 12 is a double door, including a first door body 121 and a second door body 122. The first door body 121 may be a left door body of the door 12, and the second door body 122 may be a right door body of the door 12. The first door body 121 and the second door body 122 can be opened independently, providing greater convenience and flexibility for users.

[0061] The first door 121 and the second door 122 are both provided with ice making chambers 120. The two independent ice making chambers 120 not only provide users with a larger amount of ice cubes, but also allow users to prepare different types of ice cubes according to their needs. For example, one ice making chamber 120 can be used to prepare regular square ice cubes, while the other ice making chamber 120 can be used to prepare ice cubes of special shapes or sizes to meet different beverage or cooking needs of users.

[0062] In order to achieve efficient ice making and cooling cycles, each ice making compartment 120 is equipped with its own ice making air supply port 211 and ice making air return port 212. The ice making air supply port 211 is responsible for delivering cooling air or refrigerant into the ice making compartment 120 to ensure that the ice cubes are fully cooled during the making process. The ice making air return port 212 is responsible for discharging hot air or used refrigerant in the ice making compartment 120 to maintain a low temperature environment in the ice making compartment 120.

[0063] The projections of the ice-making air outlets 211 of the two ice-making chambers 120 on the rear side of the cooling chamber 210 can fall on the evaporator 13. This means that the fan 14 can directly blow the cold air in front of the evaporator 13 to the two ice-making air outlets 211. Such a design ensures efficient use of cold air, because the cold air directly comes from the evaporator 13 and has a lower temperature, which can quickly reduce the temperature of the ice-making chamber 120, thereby speeding up the preparation of ice cubes.

[0064] The projections of the two ice-making return air vents 212 on the rear side of the cooling chamber 210 may fall on both sides of the evaporator 13. This means that when the air flowing through the ice-making compartment 120 needs to be recovered and re-enters the cooling cycle, they will enter from both sides of the evaporator 13. This layout helps prevent cross-winding, that is, the mixing of air between different ice-making compartments 120. Cross-winding may cause instability in the ice making temperature, affecting the quality and production efficiency of ice cubes.

[0065] Through the above design, the airflow in the cooling chamber 210 forms an efficient cycle. The cold air generated by the evaporator 13 is directly sent to the ice making chamber 120 through the ice making air supply port 211 for making ice cubes; while the hot air in the ice making chamber 120 flows back to the evaporator 13 through the ice making air return port 212 and is reused after heat exchange. This circulation method ensures the stability of the temperature in the cooling chamber 210 and the uniformity of ice making.

[0066] like Figure 2 As shown, in the transverse direction of the cooling chamber 210 , from left to right are the first ice-making return air vent 212 , the first ice-making air supply vent 211 , the second ice-making air supply vent 211 , and the second ice-making return air vent 212 .

[0067] The first ice-making return air vent 212 is located on the left side of the cooling chamber 210 and is mainly responsible for recovering the heated air in the ice-making chamber 120 on the left side and guiding it back to the evaporator 13 for processing, thereby helping to maintain the temperature in the ice-making chamber 120 on the left side stable and ensuring the continuity of the cooling cycle.

[0068] The first ice-making air supply port 211 is located immediately after the first ice-making air return port 212 and is located at the middle left position of the cooling chamber 210, and is mainly responsible for supplying cold air to the left ice-making chamber 120. By providing low-temperature cooling air, ice cubes in the left ice-making chamber 120 can be made quickly and evenly.

[0069] The second ice-making air supply port 211 is located immediately after the first ice-making air supply port 211 and is located at the middle right position of the cooling chamber 210, and is mainly responsible for supplying cold air to the right ice-making chamber 120. By providing low-temperature cooling air, it is ensured that ice cubes in the right ice-making chamber 120 can be prepared quickly and evenly.

[0070] The second ice-making return air vent 212 is located on the right side of the cooling chamber 210, immediately after the second ice-making supply air vent 211. It is mainly responsible for recovering the heated air in the ice-making chamber 120 on the right side and guiding it back to the evaporator 13 for processing, thereby helping to maintain the temperature in the ice-making chamber 120 on the right side stable and ensuring the continuity of the cooling cycle.

[0071] In an optional embodiment, a partition plate 206 extending from front to back is provided between the first ice-making return air outlet 212 and the first ice-making air supply outlet 211. The main function of the partition plate 206 is to prevent the hot air recovered from the first ice-making return air outlet 212 from directly flowing to the first ice-making air supply outlet 211, and to ensure that the second ice-making air supply outlet 211 can deliver low-temperature cooling air. The front end of the partition plate 206 is located on the front side wall 201 of the cooling chamber 210 between the first ice-making return air outlet 212 and the first ice-making air supply outlet 211, and the rear end of the partition plate 206 extends to the left end of the evaporator 13.

[0072] In an optional embodiment, a partition plate 206 extending from front to back is provided between the second ice-making return air outlet 212 and the second ice-making air supply outlet 211. The main function of the partition plate 206 is to prevent the hot air recovered from the second ice-making return air outlet 212 from directly flowing to the second ice-making air supply outlet 211, so as to ensure that the second ice-making air supply outlet 211 can deliver low-temperature cooling air. The front end of the partition plate 206 is located on the front side wall 201 of the cooling chamber 210 between the second ice-making return air outlet 212 and the second ice-making air supply outlet 211, and the rear end of the partition plate 206 extends to the right end of the evaporator 13.

[0073] Furthermore, a fan 14 is provided between the first ice-making air supply outlet 211, the second ice-making air supply outlet 211 and the evaporator 13, and the two fans 14 can operate independently and under control. A storage air supply outlet 213 is provided at the bottom between each fan 14 and the corresponding ice-making air supply outlet 211, and the two storage air supply outlets 213 can realize rapid cooling of the storage compartment 110.

[0074] In an optional embodiment, a housing 20 is disposed inside the storage compartment 110, and the housing 20 may include a front side wall 201, a rear side wall 202, a left side wall 203, a right side wall 204, and a bottom wall 205, and these walls together enclose a closed space, i.e., a cooling chamber 210. The top wall of the storage compartment 110 serves as the top wall of the cooling chamber 210, and of course, the housing 20 itself may also have a top wall as the top wall of the cooling chamber 210.

[0075] The bottom of the housing 20 is provided with a crossbeam 15, and the two ends of the crossbeam 15 can be fixedly connected to the side walls of the storage compartment 110, so that the housing 20 and the top wall of the storage compartment 110 are spliced ​​together to form a relatively closed cooling chamber 210. The ice-making air supply port 211 and the ice-making air return port 212 are provided on the front side wall 201 of the housing 20, and the storage air supply port 213 and the storage air return port 214 are provided on the bottom wall 205 of the housing 20. The partition plate 206 can be integrally formed with the bottom wall 205 of the housing 20, so as to enhance the structural strength of the bottom wall 205.

[0076] A drain port 216 is provided in the cooling chamber 210, and the drain port 216 is located behind the evaporator 13 and is connected to a drain pipe 208 extending downward. Condensed water generated by the evaporator 13 during the refrigeration process can flow into the drain pipe 208 through the drain port 216 and be discharged outward along the drain pipe 208 in a timely manner, thereby preventing the condensed water from accumulating in the cooling chamber 210, causing the humidity in the cooling chamber 210 to be too high, and even causing bacteria to grow. In this way, the dryness and cleanliness of the cooling chamber 210 are maintained, and the cooling chamber 210 is prevented from being contaminated by bacteria growing in the cooling chamber 210 and contaminating the items in the storage chamber 110 and the ice cubes in the ice making chamber 120.

[0077] In an optional embodiment, the cooling chamber 210 has a first bottom wall 205a and a second bottom wall 205b that gradually extend downward from both sides to the middle. The first bottom wall 205a and the second bottom wall 205b are both inclined downward from front to back, so that the front side of each is higher than the rear side. Due to the inclined design of the bottom wall 205, the air flow in the cooling chamber 210 will be affected, so that the cold air can flow to the bottom center area of ​​the cooling chamber 210 more naturally. When the fan 14 is running, the cold air will be blown to the ice-making air supply port 211 to ensure that the ice cubes are fully cooled.

[0078] When the fan 14 is installed between the evaporator 13 and the ice-making air supply port 211, since the front side of the bottom wall 205 is higher than the rear side, the position of the fan 14 is naturally lower than the ice-making air supply port 211. When the fan 14 supplies air toward the ice-making air supply port 211, part of the cold air can enter the storage compartment 110 through the storage air supply port 213, so that the storage compartment 110 can be directly supplied with cold air, thereby improving the refrigeration efficiency of the storage compartment 110.

[0079] By optimizing the design of the bottom wall 205 of the cooling chamber 210, the air flow distribution can be optimized and the refrigeration efficiency of the storage compartment 110 can be improved, which can reduce the energy consumption of the entire cooling system. Because less cold air will escape into the environment, the system needs to consume less energy to maintain the required temperature.

[0080] The drain port 216 may be located in the middle of the rear side of the bottom wall 205. Since the first bottom wall 205a and the second bottom wall 205b are both inclined backward and inward, the condensed water generated by the evaporator 13 may more easily flow to the middle of the rear side of the cooling chamber 210 and be discharged through the drain port 216. This helps to reduce the problem of condensed water accumulating in the cooling chamber 210, thereby keeping the cooling chamber 210 dry and clean.

[0081] In an optional embodiment, the rear sides of the first bottom wall 205a and the second bottom wall 205b are both provided with upwardly arched protrusions, and the lateral ends of the evaporator 13 can be supported on the protrusions. The protrusions not only provide a stable installation environment for the evaporator 13, but also enhance the structural strength of the bottom wall 205 and extend the service life of the bottom wall 205.

[0082] The two ends of the cross beam 15 may be provided with a bump corresponding to each protrusion, and the shape of the bump is adapted to the shape of the protrusion. In this way, when the top wall of the cross beam 15 abuts against the bottom wall 205 of the housing 20, the bump can extend into the protrusion from bottom to top, which can prevent the housing 20 from shaking left and right.

[0083] In an optional embodiment, the storage air return vents 214 are disposed at two corners of the rear side of the bottom wall 205 of the housing 20. In this way, the air in the ice making compartment 120 flows backward in the cooling chamber 210 through the ice making air return vents 212, and the air in the storage compartment 110 flows upward in the cooling chamber 210 through the storage air return vents 214, which ensures that the air flows in different directions in the cooling chamber 210, thereby reducing the convection effect between the two.

[0084] In an optional embodiment, each storage air return port 214 is connected to a downwardly extending air return duct 209, the lower end of which is open and extends to the bottom wall 205 near the storage compartment 110. Such a design allows the air in the storage compartment 110 to more easily enter the air return duct 209 and then be guided to the cooling chamber 210.

[0085] Due to the arrangement of the return air duct 209, the air in the storage compartment 110 can be evenly sucked in from the bottom and returned to the cooling chamber 210 through the return air duct 209. This helps to ensure that the cold air in the storage compartment 110 is more evenly distributed, avoiding the phenomenon of local overheating or overcooling.

[0086] Furthermore, a plurality of return air holes 215 are arranged at intervals from top to bottom on the body of the return air duct 209. The return air holes 215 allow the air in the storage compartment 110 to enter the return air duct 209 in a more dispersed manner. This has the advantage of reducing the flow velocity of the air in the return air duct 209, and also reducing the return air velocity at the storage return air port 214. When the air enters the evaporator 13 at a lower velocity, it can better exchange heat with the evaporator 13, thereby improving the cooling efficiency.

[0087] In addition, due to the reduction in air flow speed, the design of the return air hole 215 also helps to reduce the noise and vibration generated when the air flows, which is of great significance for improving the running stability of the refrigerator 10 and reducing noise pollution.
