Description

Technical Field

[0001] This application relates to the field of water purifier technology, and in particular to water purifier equipment. Background Technology

[0002] As market demand continues to expand, users are demanding more and more diverse functions from water purifiers.

[0003] Currently, water purifiers have functions such as producing ice water or sparkling water. To achieve these functions, a compressor is required in the water purifier for refrigeration. During the refrigeration process, a large amount of heat energy is exchanged, resulting in a significant amount of heat being generated inside the water purifier. This heat needs to be dissipated from the equipment in a timely manner; otherwise, the ice water temperature may rise, the ice may melt before the predetermined storage time is reached, and the internal components may malfunction, reducing the machine's lifespan.

[0004] Currently, commonly used water purification equipment includes an outer casing and a fan installed inside the casing. The outer casing has an air inlet and an air outlet. When the fan is running, it forms an exhaust duct from the air inlet to the air outlet.

[0005] However, due to the low heat dissipation efficiency of this structure, the heat inside the outer shell of the water purifier cannot be dissipated in a timely manner. Utility Model Content

[0006] Therefore, it is necessary to provide a water purification device to address the problem of low heat dissipation efficiency.

[0007] A water purification device, comprising:

[0008] The housing has a second air inlet on at least one side along a third direction and a second air outlet on the rear side.

[0009] The second fan drives the airflow to flow along the direction of the second air inlet, the inside of the housing, and the second air outlet;

[0010] A first air duct is located inside the outer casing; one end of the first air duct communicates with the interior of the outer casing, and the other end communicates with the outside through the outer casing.

[0011] The third direction refers to the left and right directions of the outer shell.

[0012] The second air duct, formed by the second fan, directs heat from inside the casing to the rear. The first air duct, connecting the inside and outside of the casing, forms a guiding airflow between them, thus expelling heat from inside the casing. The simultaneous operation of the first and second air ducts improves heat dissipation efficiency, enhances the stability of various functions of the water purifier, ensures the performance of components, and extends the lifespan of the water purifier.

[0013] In some embodiments, the first air duct is disposed near the top end of the housing along a first direction, and the second fan is disposed near the bottom end of the housing along a first direction, where the first direction is the height direction of the housing.

[0014] This design utilizes a first air duct positioned near the top of the casing, while the second fan is located near the bottom. When the second air duct directs airflow outwards, some of the airflow escapes the fan's influence and rises due to the upward movement of hot air, entering the effective range of the first air duct and being guided outwards. This water purifier achieves combined exhaust and heat dissipation from both the second fan and the first air duct, thus improving heat dissipation efficiency.

[0015] In some embodiments, the housing is provided with a third air outlet, the first air duct extends along a second direction and communicates with the outside through the third air outlet, the third air outlet is provided near the front side of the housing along the second direction, the second direction being the front-rear direction of the housing.

[0016] When a water purifier is placed in a cabinet, the space in front of it is usually an open space with good air circulation. The first air duct, positioned along the second direction, directs heat from the rear of the water purifier to the front, allowing for the expulsion of hot air. This prevents hot air from accumulating inside the water purifier, improving heat dissipation, ensuring the functionality and stability of the water purifier, preventing overheating, and enhancing safety.

[0017] In some implementations, the third air outlet is located on the front side of the housing;

[0018] And / or, the third air outlet is located on the top side of the housing;

[0019] And / or, the third air outlet is located on the left and / or right side of the housing.

[0020] This water purifier helps to expel heat from inside the outer casing to the front side near the outside of the cabinet, preventing hot air from accumulating inside the purifier and being unable to escape. This allows the third air outlet to be closer to the front opening of the cabinet, making the air discharged from the third air outlet closer to the outside of the cabinet, which helps to improve the heat dissipation effect of the first air duct.

[0021] In some embodiments, the water purification device further includes:

[0022] An air guide assembly is provided at one end of which is a first air inlet communicating with the interior of the outer shell, and at the end of which is away from the first air inlet, a first air outlet is provided, and the first air outlet is connected to a third air outlet.

[0023] The air guide component is specifically designed with a first air inlet and a first air outlet to achieve the air guiding function of the air guide component.

[0024] In some embodiments, the first air inlet is positioned facing the bottom of the housing, so that the first air inlet faces the heat-generating structure such as the condenser below, making it easier for hot air to enter the first air inlet, which helps to reduce airflow resistance and improve heat dissipation.

[0025] In some embodiments, the air guide assembly includes:

[0026] The first air guide has a first air inlet at one end and a first air guide channel inside the first air guide.

[0027] The second air guide is connected to the end of the first air guide away from the first air inlet, and the second air guide is provided with a second air guide channel; the second air guide channel is connected to the first air guide channel to define the first air duct;

[0028] The second air guide is provided with a first air outlet at the end away from the first air guide, and the first air outlet is connected to the third air outlet.

[0029] This air guide assembly defines a first airflow channel inside the housing, guiding the air inside the housing to the outside, which is beneficial for cooling and heat dissipation. Furthermore, the air guide assembly has a split structure design, which facilitates the placement of the first air guide channel within the first air guide component and the second air guide channel within the second air guide component. This avoids the air guide assembly having a large dimension along the second direction, and prevents the first airflow channel from increasing the manufacturing cost of the air guide assembly. Therefore, the split structure of the first and second air guide components helps reduce manufacturing difficulty and thus manufacturing costs.

[0030] In some embodiments, the first air guide includes:

[0031] Upper shell;

[0032] The lower housing is disposed opposite to the upper housing, and one of the upper housing and the lower housing is connected to the outer shell. The upper housing and the lower housing are connected and enclosed to form the first air guide channel.

[0033] The first air guide component is provided by two separate structures, an upper shell and a lower shell, which facilitates the assembly and disassembly of the first fan.

[0034] In some embodiments, the air guide assembly further includes:

[0035] First fan;

[0036] A baffle is disposed in the first air guide channel and divides the first air guide channel into an air intake chamber and an air exhaust chamber; the baffle has a vent; the air intake chamber is connected to the first air inlet, the first fan is disposed in the air intake chamber and is connected to the air exhaust chamber through the vent; the air exhaust chamber is connected to the vent and the second air guide channel.

[0037] Setting up an air intake chamber and an air exhaust chamber in the first air guide channel located upstream of the first air duct is beneficial to improving the airflow extraction effect of the first fan, thereby improving the heat dissipation efficiency.

[0038] In some embodiments, the housing is provided with a slot, which is disposed on the inner wall of the housing and extends along a third direction or along a second direction, wherein the second direction is the front-rear direction of the housing;

[0039] The second air guide includes a body and a flange, the flange being connected to the body and engaging with the slot.

[0040] The connection between the second air guide and the outer casing is simple, and the connection can be achieved simply by sliding the flange in the slot, which is easy to operate. Attached Figure Description

[0064] Figure 1 A schematic diagram of the water purification device provided in this embodiment is shown. Figure 1 , Figure 2 A schematic diagram of the water purification device provided in this embodiment is shown. Figure 2 , Figure 3 A schematic diagram of the water purification device provided in this embodiment is shown. Figure 3 .

[0065] like Figures 1 to 3 As shown, this embodiment provides a water purification device. The device includes a housing 100, which comprises a top plate 120, a left side plate 130, a right side plate 140, a rear side plate 150, a front side plate 160, and a bottom plate, forming a space for the internal structure. A water outlet 170 and a water receiving space 180 are located at the front of the housing 100, below the water outlet 170 for easy water dispensing by the user. The water outlet 170 is mounted on the front side plate 160, which is recessed rearward to form the water receiving space 180. To prevent liquid from splashing onto the countertop when the user dispensing water, a support plate 190 is provided below the water receiving space 180. The support plate 190 is connected to the front side plate 160, allowing the user to place their water dispensing tool on the support plate 190. The support plate 190 can be equipped with a water tank, which can retain water that overflows or splashes outside, thereby improving the user experience.

[0066] A control panel can be installed on the front panel 160 to facilitate user operation and control of the water purification equipment.

[0067] It should be noted that, for reference Figure 1 As shown, the water purifier has a vertical direction (first direction Z), a front-back direction (second direction X), and a left-right direction (third direction Y); the vertical direction is also the height direction of the water purifier. The left side panel 130 and the right side panel 140 are distributed along the left-right direction of the water purifier; the front side panel 160 and the rear side panel 150 are distributed along the front-back direction of the water purifier; the top panel 120 is located at the top of the water purifier.

[0068] Optionally, the water purifier can produce room temperature water, hot water, ice water, ice, or sparkling water to meet diverse user needs. In this case, the water purifier can also be equipped with a compressor or other refrigeration structure to produce ice water. The water purifier can also be equipped with a heating element (not shown in the figure) to produce hot water.

[0069] The heating components and compressor generate a lot of heat when they are working. If the heat is not dissipated in time, the temperature of the ice water will rise, the ice will melt before the predetermined storage time is reached, and the internal components will malfunction, and the lifespan of the water purifier will be reduced.

[0070] like Figure 3 and Figure 4 As shown, the outer casing 100 has a second air inlet 131 on at least one side along the third direction Y, and a second air outlet 151 on the rear side along the second direction X. The water purification device also includes a second fan 400, which drives airflow along the direction of the second air inlet 131, the interior of the outer casing 100, and the second air outlet 151, thereby forming a second air duct 500. The water purification device, through the driving force of the second fan 400, forms an airflow channel between the second air inlet 131, the interior of the outer casing 100, and the second air outlet 151, achieving a cooling effect through airflow. Exemplarily, the second fan 400 is a fan that achieves airflow by rotating fan blades to disturb the airflow.

[0071] At the same time, the second fan 400 is positioned near the lower end of the housing 100 along the second direction X, which allows it to be positioned in relation to the main heat-generating structure such as the compressor, thus improving the heat dissipation effect.

[0072] Furthermore, the second air inlet 131 can be located on the left side plate 130 or the right side plate 140, or both the left and right side plates 130 and 140 can have the second air inlet 131 located on the rear side plate 150. The second fan 400 is located on the second air outlet 151, thereby creating a suction airflow at the second air outlet 151, drawing out the gas inside the casing and creating a negative pressure inside the casing. Under the action of external atmospheric pressure, external gas will enter the outer casing 100 through the second air inlet 131 to replenish the air pressure, thereby creating airflow between the second air inlet 131 and the second air outlet 151.

[0073] For example, the second air inlet 131 is a grid hole, which helps to prevent dust from easily entering the second air inlet 131 and is also beneficial to aesthetics.

[0074] For example, the outer periphery of the second air outlet 151 is correspondingly configured with the fan, and the second air outlet 151 is provided with multiple baffles and blocks. The blocks are located at the center of the second air outlet 151, and the diameter of the blocks is smaller than the diameter of the fan's windless zone. One end of each baffle is connected to the block, and the other end is arranged in a radiating pattern along the circumference of the block, so that the extended square of the baffle is the same as that of the fan blades. This facilitates the airflow disturbed by the rotation of the fan blades to flow out from the gap between two adjacent baffles, reducing airflow resistance. At the same time, the structure of the baffles and blocks helps to prevent the fan from being directly exposed and causing danger, and also helps to maintain aesthetics.

[0075] In addition, since the compressor and other structures are usually located near the lower end inside the housing 100, in order to improve the heat dissipation effect, the second air inlet 131 is located near the lower end of the left side plate 130 and the right side plate 140, and the second air outlet 151 is located near the lower end of the rear side plate 150, so that the second air duct 500 is located near the lower end of the housing 100, so that the second air duct 500 is correspondingly set with the heat-generating structures such as the compressor, which is conducive to improving the heat dissipation effect.

[0076] Currently, users typically install water purifiers inside cabinets, which effectively improves cabinet space utilization and enhances the aesthetics and tidiness of the room. However, the single-use forced exhaust fan (400MHz) generates significant noise, reducing the user experience.

[0077] To resolve the above issues, please refer to [link / reference]. Figure 3 The water purifier also includes a first air duct 200 located within the outer casing 100. One end of the first air duct 200 connects to the interior of the outer casing 100, and the other end connects to the outside through the outer casing 100, thus forming a first air duct 200 with a guiding function between the interior and exterior of the outer casing 100, allowing heat from the interior of the outer casing 100 to be discharged through the first air duct 200. The simultaneous operation of the first air duct 200 and the second air duct 500 improves heat dissipation efficiency, enhances the stability of various functions of the water purifier, ensures the performance of components, and extends the service life of the water purifier.

[0078] like Figure 3As shown, in some embodiments, the first air duct 200 is positioned near the top of the outer casing 100 along the first direction Z, placing the first air duct 200 above the second fan 400. This embodiment utilizes the first air duct 200's proximity to the top of the outer casing 100. Since the second fan 400 is positioned near the bottom of the outer casing 100, when the second air duct 500 directs airflow towards the outside of the outer casing 100, some airflow escapes the action of the second fan 400 and moves upwards due to the upward movement of hot air, thus entering the effective range of the first air duct 200 and being guided to the outside of the outer casing 100 by the first air duct 200. This water purifier achieves joint exhaust and heat dissipation by the second fan 400 and the first air duct 200, thereby improving heat dissipation efficiency. When the water purifier is installed in a cabinet, the first air duct 200 directs heat from inside the outer casing 100 to the normally open space near the front of the cabinet, while the second air duct 500 simultaneously directs heat from below the outer casing 100 into the cabinet.

[0079] like Figure 3 and Figure 4 As shown, the lower part of the water purifier is cooled by the second air duct 500 and the second fan 400. Some of the hot air that is not discharged in time flows upward. The first air duct 200 located above can discharge the hot air that overflows into the air flow range of the second air duct 500, thereby improving the heat dissipation effect.

[0080] like Figure 3 As shown, in some embodiments, the outer casing 100 is provided with a third air outlet 121, and the first air duct 200 extends along the second direction X and communicates with the outside through the third air outlet 121. The third air outlet 121 is located near the front side of the outer casing 100 along the second direction X, where the second direction X is the front-rear direction of the outer casing 100. When the water purifier is placed in a cabinet, the space in front of the water purifier is usually an open space with good air circulation. By extending the first air duct 200 along the first direction X, that is, by extending the first air duct 200 along the front-rear direction of the water purifier, and exhausting air through the third air outlet 121 near the front side of the outer casing 100, the heat from the rear of the water purifier can be diverted to the front, thereby achieving the exhaust of hot air and preventing hot air from accumulating inside the water purifier and being unable to escape. This is beneficial for improving heat dissipation, ensuring the functionality and stability of the water purifier, preventing the water purifier from overheating due to excessive temperature, and improving safety.

[0081] like Figures 3 to 6 , Figure 8 as well as Figure 9As shown, the third air outlet 121 is located on the front side of the outer casing 100, and / or, the third air outlet 121 is located on the top of the outer casing 100, and / or, the third air outlet 121 is located on the left and / or right side of the outer casing 100. That is, the third air outlet 121 can be set on any one or more of the front side panel 160, left side panel 130, right side panel 140, or top panel 120. When the first air outlet 321 is located on the upper left side panel 130, right side panel 140, or top panel 120, the third air outlet 121 is set close to the front end of the outer casing 100, so that the third air outlet 121 is close to the front opening of the cabinet, and the air discharged from the third air outlet 121 is closer to the outside of the cabinet, which is beneficial to improving the heat dissipation effect of the first air duct 200.

[0082] The third air outlet 121 is a grille, which helps to prevent dust from easily entering the third air outlet 121 and also improves the aesthetics.

[0083] The water purification equipment includes an air guide assembly 300. See the diagram below. Figure 3 , Figure 4 , Figures 8 to 11 The detailed structure of the air guide assembly 300 is explained.

[0084] like Figure 3 , Figure 4 , Figures 8 to 9 As shown, in some embodiments, one end of the air guide assembly 300 is provided with a first air inlet 313 communicating with the interior of the housing 100, and the other end of the air guide assembly 300 away from the first air inlet 313 is provided with a first air outlet 321, which communicates with a third air outlet 121. The air guide assembly specifically includes a first air inlet 313 and a first air outlet 321 to achieve the air guiding function of the air guide assembly 300.

[0085] like Figure 4 and Figure 9 As shown, in some embodiments, the first air inlet 313 is positioned facing the bottom of the housing 100, so that the first air inlet 313 faces the heat-generating structure such as the condenser below, making it easier for hot air to enter the first air inlet 313, which helps to reduce airflow resistance and improve heat dissipation.

[0086] Furthermore, the air guiding assembly 300 includes a first air guiding member 310 and a second air guiding member 320. One end of the first air guiding member 310 defines a first air inlet 313, and a first air guiding channel 210 is provided inside the first air guiding member 310. The end of the second air guiding member 320 away from the first air guiding member 320 has a first air inlet 313, and a second air guiding channel 220 is provided inside the second air guiding member 320; the second air guiding channel 220 communicates with the first air guiding channel 210 to define a first air duct 200; the end of the second air guiding member 320 away from the first air guiding member 310 has a first air outlet 321, and the first air outlet 321 communicates with a third air outlet 121.

[0087] The air guide assembly 300 defines a first air duct 200 inside the outer casing 100, enabling the air inside the outer casing 100 to flow to the outside, which is beneficial for cooling and heat dissipation inside the outer casing 100. Furthermore, the air guide assembly 300 has a split structure design, which facilitates the placement of the first air guide channel 210 within the first air guide component 310 and the second air guide channel 220 within the second air guide component 320. This avoids the air guide assembly 300 having a large dimension along the second direction, and prevents the first air duct 200 from increasing the processing cost of the air guide assembly 300. Therefore, the split structure of the first air guide component 310 and the second air guide component 320 helps reduce processing difficulty and thus processing costs.

[0088] During operation, the air inside the outer casing 100 enters the first air guide channel 210 and flows through the first air guide channel 210 to the second air guide channel 220, and finally is discharged to the outside through the first air outlet 321 and the third air outlet 121 of the second air guide channel 220.

[0089] In some embodiments, the first air guide 310 and the second air guide 320 are detachably coupled. This air guide assembly 300 structure facilitates assembly, disassembly, and maintenance. Specifically, the first fan 330 is housed within the first air guide 310. Furthermore, the separate structure makes cleaning easier when dust accumulates inside the air guide assembly 300.

[0090] Specifically, the first air guide 310 and the second air guide 320 are interlocked to facilitate assembly and disassembly, thereby improving operational efficiency. It is worth noting that during assembly, the first air guide 310 is inserted into the second air guide 320, ensuring that the connection point of the first air guide 310 and the second air guide 320 aligns with the airflow direction, which helps reduce airflow leakage.

[0091] Alternatively, the first air guide 310 and the second air guide 320 can be engaged in a snap-fit ​​configuration, which improves the stability of their connection. Specifically, the second air guide 320 has a slot 324, and the outer wall of the first air guide 310 has a protrusion 314. After the first air guide 310 is inserted into the second air guide 320, the protrusion 314 is engaged in the slot 324, thereby improving the stability of the connection between the first air guide 310 and the second air guide 320. At the same time, the slot 324 and the protrusion 314 have simple structures, are easy to assemble and disassemble, and are relatively inexpensive.

[0092] like Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, the first air guide 310 includes an upper housing 311 and a lower housing 312. The lower housing 312 is disposed opposite to the upper housing 311, and one of the upper housing 311 and the lower housing 312 is connected to the outer casing 100. The upper housing 311 and the lower housing 312 are connected and enclose to form a first air guide channel 210. The first air guide 310 is provided by two separate structures, the upper housing 311 and the lower housing 312, which facilitates the assembly and disassembly of the first fan 330.

[0093] In some embodiments, the upper housing 311 and the lower housing 312 are detachably coupled to facilitate the assembly, disassembly and maintenance of the first fan 330.

[0094] Furthermore, the upper housing 311 and the lower housing 312 are snap-fitted together, which helps to improve assembly and disassembly efficiency. For example, one of the upper housing 311 and the lower housing 312 is provided with a retaining ring 3111, and the other is provided with a snap fastener 3121. When the upper housing 311 and the lower housing 312 are assembled, the snap fastener 3121 is engaged with the retaining ring 3111. Of course, to improve the stability of the connection, there are multiple retaining rings 3111 and snap fasteners 3121, and each retaining ring 3111 and snap fastener 3121 is provided in a one-to-one correspondence.

[0095] In some embodiments, the air guiding assembly 300 further includes a first fan 330 and a baffle 350. The baffle 350 is disposed in the first air guiding channel 210 and divides the first air guiding channel 210 into an air intake chamber 211 and an air exhaust chamber 212. The baffle 350 has a vent 351. The air intake chamber 311 is connected to the first air inlet 313. The first fan 330 is disposed in the air intake chamber 311 and is connected to the air exhaust chamber 212 through the vent 351. The air exhaust chamber 212 is connected to the vent 351 and the second air guiding channel 220, so that airflow can circulate in the first air duct 200 under the drive of the first fan 330.

[0096] Setting up an air intake chamber 211 and an air exhaust chamber 212 in the first air guide channel 210 located upstream of the first air duct 200 is beneficial to improving the airflow extraction effect of the first fan 330, thereby improving the heat dissipation efficiency.

[0097] Specifically, the vent 351 of the baffle 350 is located below the upper housing 311 and communicates with the exhaust cavity 212 inside the lower housing 312 from below the lower housing 312.

[0098] Please continue reading Figure 3 , Figure 4 , Figures 8 to 9 Combining the first air inlet 313 and the first air outlet 321, the suction chamber 211 is located on one side of the first air inlet 313, which helps to reduce the size of the first air guide 310 along the first direction Z.

[0099] At this time, the first air guide 310 also includes a guide section 315. The first fan 330 can be disposed in the guide section 315. The upper end face of the guide section 315 is connected to the exhaust cavity 212. The guide section 315 is a shell structure. The guide section 315 is used to guide the airflow in the suction cavity 211 to the vent 351 under the guiding action of the first fan 330 and the guide section 315, and to flow towards the exhaust cavity 212.

[0100] When the first fan 330 rotates, it creates a negative pressure in the suction chamber 211. The suction chamber 211 is connected to the first air inlet 313, so that air enters the suction chamber 211 from the first air inlet 313. Then, under the power of the rotation of the first fan 330, it flows into the exhaust chamber 212 under the guidance of the guide part 315, and finally flows to the second air guide 320 and flows out from the first air outlet 321.

[0101] like Figure 5 and Figure 6 As shown, in some embodiments, the second air guide 320 and the outer casing 100 are plugged into each other. The plugging direction of the second air guide 320 is parallel to the third direction Y or the second direction X. The third direction Y is perpendicular to the first direction Z, which is the height direction of the outer casing 100. The third direction Y is perpendicular to both the second direction X and the first direction Z. This connection method between the second air guide 320 and the outer casing 100 can limit the second air guide 320 in the direction of gravity and also improves assembly efficiency.

[0102] Specifically, such as Figure 5 and Figure 6 As shown, the outer casing 100 is provided with a slot 110, which is disposed on the inner wall of the outer casing 100 and is arranged along a third direction Y or a second direction X. The second air guide 320 includes a body 322 and a flange 323, which is connected to the body 322 and slides in engagement with the slot 110. The connection between the second air guide 320 and the outer casing 100 is simple, and the connection is achieved simply by sliding the flange 323 in the slot 110, which is convenient for operation. For example, the slot 110 can be formed by two L-shaped limiting arms arranged opposite each other.

[0103] Now combined Figure 9 The process of assembling and disassembling the air guide assembly 300 is described.

[0104] like Figure 9 As shown, when assembling the air guide assembly 300, the user only needs to place the first fan 330 in the air intake chamber 211, and then snap the buckle 3121 into the retaining ring 3111 to connect the upper housing 311 and the lower housing 312. Then, insert the first air guide 310 into the second air guide 320 until the protrusion 314 engages in the slot 324. Finally, insert the flange 323 from one side of the slot 110 to push the second air guide 320 into the preset position, and then use screws or other connectors to connect the outer casing 100 to the first air guide 310 to complete the assembly.

[0105] The process of disassembling the air guide assembly 300 is the reverse of the above process, and will not be described in detail here.

[0106] Optionally, such as Figure 10 and Figure 11 As shown, the end face of the upper housing 311 or the lower housing 312 is connected to the rear side plate 150 by a fastener 340 to ensure the stability of the position of the first air guide 310 within the housing 100. For example, the fastener 340 is preferably a screw, which is a commonly used connector, has low cost, and is easy to assemble and disassemble.

[0107] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0108] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
