[0061] In the description of the utility model, it should be understood that the terms "first", "second" in the utility model are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.

[0062] Referring to Figure 1 As shown in the figure, the utility model embodiment provides a refrigerator 100, comprising a box body 1 and a door body, the box body 1 is formed with a taking and placing opening 2, the door body is connected with the box body 1 and can move relative to the box body 1 to open and close the taking and placing opening 2.

[0063] The box body 1 is roughly a cuboid frame structure, the box body 1 comprises a box shell 1a and a box core 1b, the box core 1b is arranged in the box shell 1a, a foaming space (not shown in the figure) is formed between the box core 1b and the box shell 1a, the foaming space is used to install other component structures of the refrigerator 100 and form a foaming heat preservation layer. The box shell 1a provides protection and support for the box core 1b. The box core 1b is formed with a refrigeration compartment for storing food 7. The taking and placing opening 2 is arranged on one side of the refrigeration compartment to facilitate taking and placing articles in the refrigeration compartment. The door body is connected to the box shell 1a of the box body 1 in a hinged manner, for example, the door body can be rotatably connected with the box shell 1a, and can also be slidably connected.

[0064] In some embodiments, the refrigerator 100 further comprises a refrigeration system (not shown in the figure) and a air supply system (not shown in the figure), the refrigeration system and the air supply system are electrically connected with a power supply assembly, the power supply assembly is used to supply power to each component of the refrigeration system and the air supply system, thereby ensuring the normal work of the refrigeration system and the air supply system.

[0065] The refrigeration system is installed in the cabinet shell 1a, and is used to provide cold air to the refrigeration compartment inside the cabinet liner 1b. The refrigeration system generally refers to a closed system composed of 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 in the cabinet shell 1a according to its structural characteristics to meet the requirements of its corresponding functions. The working process of the refrigeration system mainly includes compression process, condensation process, throttling process and evaporation process. The compression process is as follows: after the power cord of the refrigerator 100 is plugged in and the contacts of the temperature controller are connected, the compressor starts to work. The low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into high-temperature and high-pressure refrigerant gas after the action of the compressor, and is then discharged into the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, and the temperature drops. The high-temperature and high-pressure refrigerant gas is gradually cooled into a saturated vapor of the refrigerant at room temperature and high pressure, and is cooled into a saturated liquid of the refrigerant. The throttling process is as follows: the saturated liquid of the refrigerant after condensation flows into the throttling device after filtering out water and impurities by the drying filter. The throttling device is throttled to reduce the pressure, and the refrigerant becomes a wet vapor at room temperature and low pressure. The evaporation process is as follows: the wet vapor at room temperature and low pressure enters the evaporator, starts to absorb heat and vaporizes, reduces the temperature of the evaporator and its surrounding, realizes refrigeration, and makes the refrigerant into a low-temperature and low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor, and the above process is repeated. Through the state change of the refrigerant, energy conversion is realized, the heat in the refrigerator 100 is transferred to the air outside the cabinet, and the refrigeration cycle of the refrigerator 100 is realized.

[0066] The air supply system is installed in the cabinet shell 1a and is used to provide power for the cold air flow; the air supply system generally includes a fan and an air supply air duct defined in the cabinet shell 1a. In some embodiments, the air inlet end of the air supply air duct is arranged close to the fan, and the air outlet end of the air supply air duct is arranged away from the fan. In other embodiments, the air outlet end of the air supply air duct is arranged close to the fan, and the air inlet end of the air supply air duct is arranged away from the fan. The cabinet shell 1a further defines an air duct cavity, which is in communication with the air supply air duct and the refrigeration compartment inside the cabinet liner 1b, so that the air supply air duct is in communication with the refrigeration compartment through the air duct cavity. It should be noted that the cabinet liner 1b is provided with an air outlet for communicating the air duct cavity with the refrigeration compartment. The cold air generated by the refrigeration system is introduced into the air duct cavity through the air supply air duct by the operation of the fan, and flows to the refrigeration compartment through the air outlet to refrigerate the refrigeration compartment. It should be noted that in some embodiments, the air outlet is arranged on the side wall opposite to the access opening 2 of the refrigeration compartment of the cabinet liner 1b, or on the side wall adjacent to the access opening 2 of the refrigeration compartment of the cabinet liner 1b. It should be noted that the refrigeration system and the air supply system are common technical knowledge in the art, and will not be described here.

[0067] Embodiment 1

[0068] Reference Figures 1-7The refrigerator 100 of the embodiment 1 of the present application has a freezing compartment 3 as a first compartment in a cabinet 1, and a cold air outlet (not shown in the figure) is arranged in the freezing compartment 3, which is communicated with a supply system of the refrigerator 100, and the supply system sends cold air into the freezing compartment 3 through the cold air outlet.

[0069] The rotating assembly is arranged in the freezing compartment 3, wherein the rotating assembly comprises a container 4 and a motor 5, the container 4 is detachably connected with an output shaft of the motor 5, so that the container 4 can rotate relative to the freezing compartment 3, and the container 4 is provided with a cavity 4a.

[0070] The motor 5 is fixedly installed in the freezing compartment 3 through a motor 5 seat, and the output shaft of the motor 5 is connected with the container 4, when the motor 5 is driven to act, the output shaft of the motor 5 drives the container 4 to act, so that the container 4 and the output shaft of the motor 5 synchronously rotate in the clockwise direction and the counterclockwise direction.

[0071] The two contact blocks 6 are made of metal, so that the two contact blocks 6 can exchange heat with the cold air in the freezing compartment 3, the two contact blocks 6 absorb the cold energy of the freezing compartment 3, and the temperature of the two contact blocks 6 approaches the set temperature of the freezing compartment 3. Of course, the container 4 can also be made of metal, so that the container 4 as a whole can absorb the cold energy of the freezing compartment 3, so that the two contact blocks 6 can exchange heat with other parts of the container 4 when the temperature of the two contact blocks 6 rises, so that the two contact blocks 6 can be quickly cooled.

[0072] Since the contact blocks 6 can absorb the cold of the freezing chamber 3, after the user puts the food 7 into the cavity 4a, the food 7 can be attached to the side of the contact blocks 6 facing the cavity 4a, so as to exchange heat with the contact blocks 6, and then the food 7 is quickly frozen. Taking a steak as an example, the steak usually has two relatively flat and opposite sides, which are the first side 7a and the second side 7b. When the user puts the steak into the cavity 4a, the user can contact the first side 7a of the steak with one of the contact blocks 6. At this time, since the contact block 6 absorbs the cold of the freezing chamber 3, the temperature of the contact block 6 is lower than that of the steak, so that the contact block 6 exchanges heat with the steak for the first time, the heat of the steak is transferred to the container 4, so that the temperature of the steak decreases, and the steak is frozen. At the same time, the temperature of the current contact block 6 in contact with the steak rises. In order to facilitate the description, the current contact block 6 in contact with the steak is defined as the first contact block 6a, and the other contact block 6 adjacent to the first contact block 6a is defined as the second contact block 6b.

[0073] After the steak continues to exchange heat with the first contact block 6a for a period of time, the motor 5 can drive the container 4 to rotate, and as the container 4 rotates, the first contact block 6a in contact with the steak gradually becomes vertical. Under the action of gravity and centrifugal force, the steak gradually moves to the position where the two contact blocks 6 meet, and as the container 4 further rotates, the steak falls off the first contact block 6a and flips onto the second contact block 6b, and the second side 7b of the steak flips to contact the second contact block 6b. In this way, the second contact block 6b exchanges heat with the second side 7b of the steak, so that the steak can be bidirectionally frozen. Moreover, when the second contact block 6b exchanges heat with the second side 7b of the steak, the first contact block 6a exchanges heat with the cold air of the freezing chamber 3, so that the temperature of the first contact block 6a decreases and approaches the set temperature of the freezing chamber 3 again. In this way, after the steak continues to exchange heat with the second contact block 6b for a period of time, the motor 5 can drive the container 4 to rotate in the opposite direction, so that the steak flips again to the first contact block 6a, and the first side 7a of the steak contacts the first contact block 6a again. The above process is repeated, so that the steak flips between the first contact block 6a and the second contact block 6b, and the steak is bidirectionally and quickly frozen.

[0074] It should be noted that in the present embodiment 1, the flipping of the food 7 means that the food 7 is flipped by 180°, for example, the food 7 is flipped from the first side 7a facing up and the second side 7b facing down to the first side 7a facing down and the second side 7b facing up.

[0075] It should be noted that the refrigeration system and the air supply system of the refrigerator 100 are not continuously operated. After the temperature of the freezing chamber 3 reaches the preset temperature, the refrigeration system and the air supply system are often stopped until the temperature of the freezing chamber 3 exceeds the set threshold, and the refrigeration system and the air supply system are restarted. With the cooperation of the motor 5 and the container 4, the rotation of the container 4 itself can promote heat exchange between the container 4 and the cold air of the freezing chamber 3. Even in the case where the freezing chamber 3 is not supplied with cold air, the contact block 6 will also absorb the cold of the freezing chamber 3, so that the contact block 6 not in contact with the food 7 is quickly cooled, and the cooling efficiency of the container 4 itself is not easily affected by the flow of cold air in the freezing chamber 3, so that the container 4 can realize stable and rapid freezing.

[0076] It can be understood that the food 7 placed on the contact block 6 is in direct contact with the contact block 6, and the heat exchange mode between the two is heat conduction. Compared with the existing method of rapidly freezing food 7 by using heat convection, the refrigerator 100 utilizes the container 4 to contain food 7, and the food 7 exchanges heat with the contact block 6 in the form of heat conduction, which can improve the heat exchange efficiency of the food 7 and shorten the time of the food 7 passing through the ice crystal generation zone.

[0077] In the process of heat conduction, the contact area between the food 7 and the contact block 6 will affect the heat exchange efficiency of the food 7 and the contact block 6. Therefore, in some refrigerators 100, the two contact blocks 6 of the cavity 4a are respectively a first contact block 6a and a second contact block 6b, and the first contact block 6a and the second contact block 6b are arranged in sequence along the rotation direction of the container 4. The side surface of the first contact block 6a in the cavity 4a is a first contact surface 6a1, and the side surface of the second contact block 6b in the cavity 4a is a second contact surface 6b1. The first contact surface 6a1 and the second contact surface 6b1 can be set as a plane. Through the plane structure of the first contact surface 6a1 and the second contact surface 6b1, these refrigerators 100 can make the food 7 fully contact with the first contact surface 6a1 and the second contact surface 6b1, and improve the heat exchange efficiency of the food 7 and the first contact block 6a and the second contact block 6b. Of course, in other structures of the refrigerator 100, only the first contact surface 6a1 or the second contact surface 6b1 can be set as a plane to adapt to the food to be received by the container 4.

[0078] It can be understood that, during the rotation of the container 4, the contact blocks 6 in contact with the food 7 will gradually become vertical, and the food 7 will gradually move to the position where the two contact blocks 6 intersect under the action of gravity and centrifugal force. In order to avoid the food 7 directly sliding from the current contact block 6 to the adjacent another contact block 6, causing the food 7 to fail to flip, the intersection angle between the two contact blocks 6 is suitably controlled within a certain range. For example, as an example of the present embodiment, the intersection angle between the first contact surface 6a1 and the second contact surface 6b1 is α1, and the intersection angle α1 is 90°. In this way, the sliced pork, sliced beef and other regular meat slices will slide to the position where the two contact blocks 6 intersect during the rotation of the container 4, and will abut against the position where the two contact blocks 6 intersect under the action of gravity and centrifugal force, and will not directly slide onto another contact block 6. Of course, in other refrigerators 100, the intersection angle α1 can also be selected within the range of 80°-100°.

[0079] It can be understood that the container 4 is provided with an opening 4b1 communicating with the cavity 4a for the user to take and place the food 7. The two contact blocks 6 or one of the contact blocks 6 arranged in the cavity 4a are usually arranged opposite to the opening 4b1, so that when the user places the food 7 into the cavity 4a, the food 7 can be directly placed on one of the contact blocks 6 without the need for additional angle adjustment. Figure 3 As an example of the present embodiment, the container 4 includes a shell 4b and a cover 4c. The shell 4b is detachably connected with the output shaft of the motor 5, and the cavity 4a is formed in the shell 4b. The shell 4b is provided with an opening 4b1 communicating with the cavity 4a. The cover 4c is detachably connected with the opening 4b1 to separate the cavity 4a from the external environment.

[0080] Of course, in order to promote the gas flow between the inside and outside of the cavity 4a, the cover 4c can be provided with a gas permeable hole 4d, and the gas permeable hole 4d penetrates into the cavity 4a. In this way, during the rotation of the container 4, the cold air in the freezing compartment 3 can be sucked into the cavity 4a through the gas permeable hole 4d, thereby promoting the gas flow between the inside and outside of the cavity 4a, allowing the cold air in the freezing compartment 3 to enter the cavity 4a and exchange heat with the food 7 in the cavity 4a, so that the food 7 in the cavity 4a is cooled in the manner of heat convection and heat conduction.

[0081] Embodiment 2

[0082] The difference between the present embodiment 2 and the embodiment 1 is that the shell 4b of the present embodiment 2 is a box body with a square outer contour. As shown in Figure 8 The container 4 has three contact blocks 6 arranged in sequence along the rotation direction of the container 4, which are a first contact block 6a, a second contact block 6b and a third contact block 6c6, and the first contact block 6a, the second contact block 6b and the third contact block 6c6 are metal blocks.

[0083] With the cooperation of the first contact block 6a, the second contact block 6b and the third contact block 6c6, the refrigerator 100 of the present embodiment 2 can quickly freeze the food 7:

[0084] The first face 7a of the food 7 is placed on the second contact block 6b, so that the container 4 is maintained in a stationary state; in this process, the food 7 exchanges heat with the second contact block 6b, so that the temperature of the food 7 is lowered, and the temperature of the second contact block 6b is raised.

[0085] After the food 7 exchanges heat with the second contact block 6b for a period of time, the motor 5 is actuated to drive the container 4 to rotate counterclockwise, so that the food 7 in the container 4 is flipped from the second contact block 6b to the first contact block 6a, and the second face 7b of the food 7 is in contact with the first contact block 6a; at this time, the motor 5 stops running, so that the container 4 is again maintained in a stationary state, the food 7 exchanges heat with the first contact block 6a, so that the temperature of the food 7 is lowered, and the temperature of the first contact block 6a is raised; and the second contact block 6b exchanges heat with the cold air of the freezing compartment 3, so that the second contact block 6b is cooled.

[0086] After the food 7 exchanges heat with the first contact block 6a for a period of time, the motor 5 is actuated to drive the container 4 to rotate clockwise, so that the food 7 in the container 4 is flipped from the first contact block 6a to the second contact block 6b, and the first face 7a of the food 7 is in contact with the second contact block 6b; at this time, the motor 5 stops running, so that the container 4 is again maintained in a stationary state, the food 7 exchanges heat with the second contact block 6b, so that the temperature of the food 7 is lowered, and the temperature of the second contact block 6b is raised; and the first contact block 6a exchanges heat with the cold air of the freezing compartment 3, so that the first contact block 6a is cooled.

[0087] After the food 7 exchanges heat with the second contact block 6b for a period of time, the motor 5 is actuated to drive the container 4 to rotate clockwise, so that the food 7 in the container 4 is flipped from the second contact block 6b to the third contact block 6c6, and the first face 7a of the food 7 is in contact with the third contact block 6c6; at this time, the motor 5 stops running, so that the container 4 is again maintained in a stationary state, the food 7 exchanges heat with the third contact block 6c6, so that the temperature of the food 7 is lowered, and the temperature of the third contact block 6c6 is raised; and the second contact block 6b exchanges heat with the cold air of the freezing compartment 3, so that the second contact block 6b is cooled.

[0088] By repeating the above steps, the rotating assembly of this embodiment 2 can make the food 7 exchange heat with the first contact block 6a, the second contact block 6b and the third contact block 6c6 respectively, and the first contact block 6a, the second contact block 6b and the third contact block 6c6 as the metal cooling surface can make the food 7 placed in the cavity 4a fully contact with the three contact blocks 6 respectively, so that the food 7 can be fully cooled, so that the refrigerator 100 using the rotating assembly can reach the cooling speed shown in FIG. 4.

[0089] It should be noted that in this embodiment 2, the side of the first contact block 6a in the cavity 4a is the first contact surface 6a1, the side of the second contact block 6b in the cavity 4a is the second contact surface 6b1, and the side of the third contact block 6c6 in the cavity 4a is the third contact surface, and the angle between the first contact surface 6a1 and the second contact surface 6b1 is α1, and the angle α1 is 90°, and the angle between the second contact surface 6b1 and the third contact surface is α2, and the angle α2 is 90°, so that the first contact block 6a, the second contact block 6b and the third contact block 6c6 of this embodiment 2 can achieve the cooperation of the first contact block 6a and the second contact block 6b of embodiment 1. Of course, in other refrigerators 100, the angle α1 can also be selected within the range of 80°-100°, and the angle α2 can also be selected within the range of 80°-100°.

[0090] The container 4 of the refrigerator 100 can contain meat with regular outer contour shape, such as sliced beefsteak, sliced beefsteak, and can also contain meat with irregular outer contour shape, such as chicken wing roots, pork tenderloin, etc. The meat with irregular outer contour shape is easy to roll in the cavity 4a, especially when the container 4 rotates, the meat with irregular outer contour shape is easy to move relative to the contact block 6, and the thickness of the meat will affect the difficulty of the meat turning over in the container 4, the thicker the meat, the more difficult it is to turn over in the container 4, so in some refrigerators 100, a limiting structure can be provided in the container 4 to limit the sliding of the food 7 relative to the contact block 6 and assist the food 7 to turn over in the container 4.

[0091] Reference Figure 9 As an example of this embodiment, the container 4 is connected to a limiting block 9, the limiting block 9 extends into the cavity 4a and extends to the side of the contact block 6 facing the cavity 4a to form a fulcrum for the food 7 to turn over to the adjacent contact block 6.

[0092] With the side of the first contact block 6a in the cavity 4a as the first contact surface 6a1 and the side of the second contact block 6b in the cavity 4a as the second contact surface 6b1, it can be understood that the limiting block 9 is usually arranged close to the first contact surface 6a1 and the second contact surface 6b1, so that the limiting block 9 can not hinder the turning over of the food 7 in the cavity 4a.

[0093] The limiting block 9 can constrain the food 7 to slide relative to the contact block 6, so that the food 7 can still keep a relatively static state with the contact block 6 when the container 4 rotates at a small angle, and the heat exchange efficiency between the food 7 and the contact block 6 is ensured. Moreover, under the action of the limiting block 9, the first contact block 6a in contact with the food 7 will gradually become vertical, and the steak will gradually move to the position of the limiting block 9 under the action of gravity and centrifugal force, and abut against the limiting block 9. Furthermore, as the container 4 further rotates, the food 7 will flip over the limiting block 9 as a turning fulcrum, and flip over to the second contact block 6b, thereby separating from the first contact block 6a and flipping and falling onto the second contact block 6b.

[0094] It should be noted that the limiting block 9 serves as a fulcrum for the food 7 to flip over to the adjacent contact block 6, and it is necessary to ensure that the limiting block 9 does not hinder the food 7 in the cavity 4a from flipping between the two contact blocks 6, and it is necessary to ensure that the food 7 will be in contact with the limiting block 9 during the flipping process, rather than directly abutting against the contact block 6 to be flipped. Therefore, the outer diameter of the portion of the limiting block 9 extending into the cavity 4a is usually smaller than the thickness of the food 7, or the portion of the limiting block 9 extending into the cavity 4a is designed with a curved surface to reduce the contact area between the food 7 and the limiting block 9, so as to ensure that the food 7 can flip over the limiting block 9 as a turning fulcrum.

[0095] For example, referring to Figure 10 As an example of the present embodiment, the limiting block 9 includes a limiting portion 9a extending into the cavity 4a, and the outer peripheral surface of the limiting portion 9a is a circular arc surface, so that the contact position between the food 7 and the limiting portion 9a is only a small segment of the circular arc. Moreover, the limiting portion 9a can be arranged parallel to the rotation axis of the container 4, so that the limiting portion 9a extends along the direction of the rotation axis of the container 4. In this way, as the container 4 rotates, the food 7 is more likely to flip over the limiting portion 9a as a turning fulcrum, and the food 7 can be flipped over to different contact blocks 6 to exchange heat with different contact blocks 6, thereby achieving rapid freezing of the food 7.

[0096] Of course, the cooperation between the food 7 of different shapes and sizes and the limiting block 9 is different, and therefore the limiting block 9 and the container 4 can be detachably connected and matched, so that the container 4 can replace or change the corresponding limiting block 9 or adjust the position of the limiting block 9 according to the shape of the food 7 put in, so as to ensure that the limiting block 9 can cooperate with the food 7 in the cavity 4a and serve as a fulcrum for the food 7 to flip over to the adjacent contact block 6. Moreover, according to the rotating action of the container 4, the number of limiting blocks 9 arranged on the container 4 can be multiple, and the multiple limiting blocks 9 are arranged adjacent to the intersection position of the two contact blocks 6, so that the food 7 in the cavity 4a can cooperate with the corresponding limiting block 9 when the container 4 rotates clockwise and counterclockwise, and the food 7 can be flipped over.

[0097] Embodiment 3

[0098] The difference between this embodiment 3 and embodiment 2 is that the refrigerator 100 provided by this embodiment 3 comprises the bracket 8, the container 4 and the motor 5, wherein, referring to Figure 15 , the bracket 8 is provided with a taking and placing opening 2 (not shown in the figure), and the taking and placing opening 2 penetrates through the bracket 8; the container 4 penetrates through the taking and placing opening 2 and is connected with the bracket 8, and the container 4 can be taken out of the bracket 8 through the taking and placing opening 2; the output shaft of the motor 5 is connected with the bracket 8 to drive the bracket 8 to rotate. Of course, in some refrigerators 100, the bracket 8 can have a space capable of storing objects inside to place the container 4, so in these refrigerators 100, the taking and placing opening 2 of the bracket 8 can be communicated to the space inside the bracket 8.

[0099] Under the cooperation of the bracket 8 and the container 4, the user can conveniently take down the container 4 and take it out of the refrigerator 100, and in a suitable scene, the food 7 and the meat are stored in the container 4, so that the user does not need to store the food 7 in the relatively limited space of the freezing compartment 3, which is beneficial to improve the operation experience of the user, and the container 4 is detachably cooperated with the bracket 8, so the output shaft of the motor 5 of this embodiment 3 can be fixedly connected with the bracket 8, thereby ensuring the stability of the transmission of the motor 5 and the bracket 8.

[0100] In order to facilitate the connection of the container 4 and the bracket 8, referring to Figure 1 , as an example of this embodiment, the bracket 8 is provided with a connecting piece (not shown in the figure), such as a magic tape, a ribbon, etc. The connecting piece is detachably connected with the bracket 8, and the connecting piece is connected with the container 4 to fix the container 4 in the bracket 8. By providing the detachably connected connecting piece, the user can conveniently fix the container 4 on the bracket 8 or take the container 4 out of the bracket 8, which is convenient for the user to take out / place the food 7 and improves the operation experience of the user.

[0101] In summary, the refrigerator 100 is configured with the container 4 in the freezing chamber 3, and the food 7 is placed in the container 4, the container 4 is driven to rotate by the motor 5, the food 7 in the container 4 is turned over, in this way, the rotation of the container 4 itself can promote the heat exchange between the container 4 and the cold air in the freezing chamber 3, so that the cooling efficiency of the container 4 itself is not easily affected by the flow of the cold air in the freezing chamber 3, so that the container 4 can realize stable and rapid freezing, and by controlling the time of maintaining the stationary state of the container 4, the contact time of the food 7 and the current contact block 6 can be ensured, so that the food 7 and the current contact block 6 can be fully heat exchanged; secondly, the contact block 6 as the cooling surface can directly contact the food 7, not only can quickly cool the food 7, but also the food 7 is turned over in the container 4, can contact different contact blocks 6, so that the contact block 6 which rises in temperature after contacting the food 7 can be cooled again, so that the container 4 can realize continuous and rapid freezing.

[0102] The above is only the preferred embodiment of the present application, it should be pointed out that for those skilled in the technical field, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, these improvements and substitutions should also be considered as the protection scope of the present application.
