Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a condensate purification device and a gas water heater. Background Technology

[0002] Gas water heaters are a common type of hot water supply equipment. Among them, condensing gas water heaters are widely used due to their high efficiency and energy saving. Specifically, condensing gas water heaters improve gas utilization efficiency and achieve energy saving through two heat exchange processes. During the secondary heat exchange process, condensate water is produced. This condensate water contains dissolved acidic gases such as sulfur oxides and nitrogen oxides from the flue gas, making it highly corrosive and unable to be directly discharged or recycled.

[0003] In related technologies, a common approach is to set up a condensate collection container and a condensate filtration module. The collected condensate is guided to the filtration module for filtration, or a container filled with neutralizing material is placed directly in the condensate flow path. As the condensate flows through the neutralizing material, it neutralizes the acid in the condensate, thus achieving acid removal. However, the residence time of the condensate in the filtration module or neutralizing material is relatively short, which cannot fully remove acidic substances from the condensate, resulting in poor purification efficiency.

[0004] Therefore, there is an urgent need for a condensate purification device and a gas water heater to solve the above problems. Utility Model Content

[0012] As an optional solution of the condensate purification device of this utility model, the first fixed cylinder has a first water outlet area, and a plurality of first water inlets are arranged circumferentially in the first water outlet area.

[0013] The second fixed cylinder has a second water outlet area, and multiple second water inlets are arranged circumferentially within the second water outlet area;

[0014] The water level in the first water outlet area is higher than the water level in the second water outlet area.

[0015] As an optional solution of the condensate purification device of this utility model, one of the first fixed cylinder and the second fixed cylinder is provided with a limiting protrusion, and the other is provided with a limiting groove. The limiting protrusion is engaged in the limiting groove to limit the relative position of the first fixed cylinder and the second fixed cylinder.

[0016] And / or, the top of the first fixed cylinder is provided with a mesh cover, and the mesh cover is provided with a plurality of water passage holes communicating with the first chamber.

[0017] As an optional solution of the condensate purification device of this utility model, the first fixed cylinder is provided with a first sealing element at one end near the water inlet, and the outer wall of the first fixed cylinder is sealed to the inner wall of the second fixed cylinder through the first sealing element.

[0018] And / or, the second fixed cylinder is provided with a second sealing element at one end near the water inlet, and the outer wall of the second fixed cylinder is sealed to the inner wall of the outer shell through the second sealing element.

[0019] As an optional solution for the condensate purification device of this utility model, the condensate purification device further includes filter cylinders, which are spaced out of the fixed cylinder assembly;

[0020] And / or, the condensate purification device further includes a magnetic attractor disposed on the fixed cylinder assembly, the magnetic attractor being used to attract magnetic substances in the condensate.

[0021] As an optional solution for the condensate purification device of this utility model, when the condensate purification device includes a filter cylinder, a plurality of support ribs are provided at intervals along the circumferential direction on the fixed cylinder assembly, and the support ribs can contact the inner wall of the filter cylinder.

[0022] When the condensate purification device includes a magnetic suction element, the fixed cylinder assembly is provided with an insert groove, and the magnetic suction element is embedded in the insert groove.

[0023] As an optional solution for the condensate purification device of this utility model, a support structure is provided at one end of the fixed cylinder assembly near the water outlet, and the support structure can support and abut against the inner wall of the outer shell.

[0024] And / or, the filter element includes an acid-base neutralizing material.

[0025] As an optional solution for the condensate purification device of this utility model, the outer shell includes a first cylindrical part and a second cylindrical part, and the ends of the first cylindrical part and the second cylindrical part facing each other are sleeved together.

[0026] The first cylindrical section is provided with a water inlet connection at one end facing away from the second cylindrical section, and the water inlet connection has the water inlet.

[0028] The beneficial effects of this utility model are as follows:

[0029] The condensate purification device provided by this utility model allows condensate to enter the first chamber through the inlet, then flow through a filter element. The filter element filters out impurities in the condensate and / or reacts with the condensate to remove impurities and harmful substances (such as acids), thus purifying the condensate discharged from the outlet to meet recycling or discharge requirements. The condensate treated by the filter element in the first chamber enters the second chamber through the first inlet, then enters the inner cavity of the outer casing through the second inlet, and finally exits through the outlet. Because the water level at the first inlet of the first chamber is higher than the water level at the second inlet of the second chamber, a certain amount of condensate is stored in the first chamber before flowing from the first inlet to the second chamber. This allows sufficient contact time (reaction time) between the condensate and the filter element, extending the flow path of the condensate, effectively filtering out impurities and harmful substances, and thus improving the purification effect of the condensate.

[0030] The gas water heater provided by this utility model has an improved purification effect because the condensate water purification device can effectively remove harmful substances from the condensate water. This ensures that when the condensate water is recycled, for example, when the purified condensate water is fed into the water circuit system of the gas water heater, the water output by the gas water heater is clean. This prevents the water from harming the skin when the user uses the water, such as for bathing or washing, thus improving water safety. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] like Figures 1 to 5 As shown, this embodiment provides a condensate purification device that can solve the problem of incomplete acid removal from condensate and improve the purification effect of condensate. The condensate purification device includes a housing 1, a fixed cylinder assembly 2, and a filter element 3.

[0050] Among them, see Figure 1 , Figure 2 and Figure 3 The outer casing 1 is provided with an inlet 110 and an outlet 120 (e.g., Figure 5 (As shown); the fixed cylinder assembly 2 is disposed inside the outer shell 1. The fixed cylinder assembly 2 is provided with a first chamber 210 and a second chamber 220 that are independent of each other and can communicate with each other. The first chamber 210 is sealed and connected to the water inlet 110. The inner wall of the first chamber 210 is provided with a first water inlet 211, which connects the first chamber 210 and the second chamber 220. The inner wall of the second chamber 220 is provided with a second water inlet 221, which connects the second chamber 220 and the inner cavity of the outer shell 1. The water level at the first water inlet 211 is greater than the water level at the second water inlet 221. The filter element 3 is disposed inside the first chamber 210. The filter element 3 can filter condensate and / or react with condensate.

[0051] The condensate purification device provided in this embodiment allows condensate to enter the first chamber 210 through the inlet 110 and then flow through the filter element 3. The filter element 3 filters out impurities in the condensate and / or reacts with the condensate to remove impurities and harmful substances (such as acids), thus purifying the condensate discharged from the outlet 120 to meet recycling or discharge requirements. The condensate treated by the filter element 3 in the first chamber 210 enters the second chamber 220 through the first inlet 211, then enters the inner cavity of the outer casing 1 through the second inlet 221, and finally is discharged from the outlet 120. Figure 3 The arrows in the diagram indicate the direction of condensate flow. Because the water level at the first inlet 211 of the first chamber 210 is higher than the water level at the second inlet 221 of the second chamber 220, the condensate in the first chamber 210 must be stored for a certain amount before flowing from the first inlet 211 to the second chamber 220. This allows sufficient contact time (reaction time) between the condensate and the filter element 3, extending the flow path of the condensate, effectively filtering out impurities and harmful substances in the condensate, and thus improving the purification effect of the condensate.

[0052] Optionally, the filter element 3 includes an acid-base neutralizing material capable of neutralizing and adjusting the pH of the condensate to prevent it from being corrosive. Exemplarily, the acid-base neutralizing material can be at least one of magnesium oxide, magnesium hydroxide, calcium carbonate, etc., or it can be a material such as an ion exchange resin, as long as it can perform both filtration and acid-base neutralization functions. In other embodiments, the filter element 3 may also include a filter cartridge.

[0053] See Figure 2 , Figure 3 , Figure 4 and Figure 5 The fixed cylinder assembly 2 includes a first fixed cylinder 21 and a second fixed cylinder 22. The second fixed cylinder 22 is spaced outside the first fixed cylinder 21. A first chamber 210 is formed inside the first fixed cylinder 21, and a second chamber 220 is defined between the second fixed cylinder 22 and the first fixed cylinder 21. That is, the second chamber 220 surrounds the first chamber 210. A first water inlet 211 is provided through the cylinder wall of the first fixed cylinder 21, and a second water inlet 221 is provided through the cylinder wall of the second fixed cylinder 22. This arrangement can effectively extend the flow path of the condensate, increase the contact reaction time between the condensate and the filter element 3, and ensure the purification effect of the condensate.

[0054] In some other embodiments, the fixed cylinder assembly 2 may also include a fixed cylinder, which is divided by a partition to form a first chamber 210 and a second chamber 220, which can also extend the flow path of condensate and improve the purification effect of condensate.

[0055] See Figure 4 and Figure 5 The first fixed cylinder 21 has a first water outlet area 212, and multiple first water inlets 211 are arranged circumferentially within the first water outlet area 212. The second fixed cylinder 22 has a second water outlet area 222, and multiple second water inlets 221 are arranged circumferentially within the second water outlet area 222. The water level in the first water outlet area 212 is higher than the water level in the second water outlet area 222, ensuring that the condensate can be temporarily stored in the first chamber 210 for a sufficient time.

[0056] The multiple first water inlets 211 allow for better control of the condensate flow rate, ensuring sufficient contact time between the condensate and the filter element 3, thus guaranteeing the condensate treatment effect. Simultaneously, the presence of multiple first water inlets 211 allows the condensate purified by the filter element 3 in the first chamber 210 to enter the second chamber 220 evenly from the circumference, improving the flow stability of the condensate. The presence of multiple second water inlets 221 allows the purified condensate to flow from all sides to the outlet 120 of the outer casing 1, improving the stability of the condensate output flow.

[0057] In this embodiment, see Figure 4 and Figure 5 The first water outlet area 212 is an annular area arranged around the first fixed cylinder 21. The first water inlet 211 is arranged in multiple rings along the axial direction. Each ring includes multiple first water inlets 211 arranged at intervals along the circumference, so that the first fixed cylinder 21 can discharge water through multiple channels along the circumference in the first water outlet area 212, and the water discharge is more uniform.

[0058] The second water outlet area 222 is an annular area arranged around the second fixed cylinder 22. The second water inlet 221 is arranged in multiple rings along the axial direction. Each ring includes multiple second water inlets 221 arranged at intervals along the circumference, so that the second fixed cylinder 22 can discharge water through multiple channels along the circumference in the second water outlet area 222, and the water discharge is more uniform.

[0059] Optionally, see Figure 2 , Figure 4 and Figure 5 One of the first fixed cylinder 21 and the second fixed cylinder 22 is provided with a limiting protrusion 213, and the other is provided with a limiting groove. The limiting protrusion 213 is engaged with the limiting groove to limit the relative position of the first fixed cylinder 21 and the second fixed cylinder 22. That is, the cooperation between the limiting protrusion 213 and the limiting groove can limit the relative movement of the first fixed cylinder 21 and the second fixed cylinder 22, ensuring that the filter element 3 is stably installed in the first fixed cylinder 21, thereby ensuring the treatment effect of condensate.

[0060] In this embodiment, the outer wall of the first fixed cylinder 21 is provided with the aforementioned limiting protrusion 213. The limiting protrusion 213 can be engaged with one of the second water inlets 221 on the second fixed cylinder 22. That is, one of the second water inlets 221 acts as a limiting groove and engages with the limiting protrusion 213, thereby limiting the relative installation position of the first fixed cylinder 21 and the second fixed cylinder 22. There is no need to separately process the limiting groove, which simplifies the processing steps of the second fixed cylinder 22.

[0061] Of course, in other embodiments, a limiting groove can be provided on the first fixed cylinder 21 and a limiting protrusion 213 can be provided on the second fixed cylinder 22, as long as the relative installation positions of the first fixed cylinder 21 and the second fixed cylinder 22 can be limited.

[0062] Optionally, see Figure 4 and Figure 5The outer wall of the first fixed cylinder 21 is provided with a limiting protrusion 213, and the inner wall of the second fixed cylinder 22 is provided with a guide groove 223. The guide groove 223 extends to the area where the second water inlet 221 is located. When assembling the first fixed cylinder 21 and the second fixed cylinder 22, the limiting protrusion 213 is aligned with the guide groove 223 and inserted, so that the limiting protrusion 213 slides along the guide groove 223 until the limiting protrusion 213 is engaged with one of the second water inlets 221 (limiting groove), and the two are then installed in place. The guide groove 223 can position the relative installation positions of the first fixed cylinder 21 and the second fixed cylinder 22, ensuring that the limiting protrusion 213 can accurately engage with the limiting groove, reducing the assembly difficulty.

[0063] For example, the inner wall of the second fixed cylinder 22 is provided with two guide grooves 223 at intervals, and the outer wall of the first fixed cylinder 21 is provided with two limiting protrusions 213. The two limiting protrusions 213 and the two guide grooves 223 are slidably engaged in a one-to-one correspondence, thereby improving the positioning accuracy of the first fixed cylinder 21 and the second fixed cylinder 22.

[0064] See Figure 3 and Figure 4 The top of the first fixed cylinder 21 is provided with a mesh cover 214, and the mesh cover 214 is provided with multiple water passage holes 2141 communicating with the first chamber 210. The multiple water passage holes 2141 enable condensate to enter the first chamber 210 evenly and dispersedly, improving filtration efficiency. At the same time, it can prevent local water flow from concentrating and scouring the filter element 3, extending the service life of the filter element 3 and reducing the replacement frequency and maintenance cost of the filter element 3. In addition, the mesh cover 214 and the multiple water passage holes 2141 can also prevent larger impurities from entering the first chamber 210, avoiding blockage.

[0065] See Figure 2 and Figure 4 The first fixed cylinder 21 has a first sealing element 23 at one end near the water inlet 110. The outer wall of the first fixed cylinder 21 is sealed to the inner wall of the second fixed cylinder 22 through the first sealing element 23. This arrangement ensures that the condensate entering from the water inlet 110 of the outer casing 1 can only flow into the first chamber 210 of the first fixed cylinder 21, preventing unfiltered condensate from entering the second chamber 220 and ensuring the effectiveness of condensate treatment.

[0066] In this embodiment, the first fixed cylinder 21 has two spaced-apart first annular protrusions 215 at one end near the water inlet 110, forming a first sealing groove 216 between the two first annular protrusions 215. A first sealing member 23 is engaged in the first sealing groove 216 and makes sealing contact with the inner wall of the second fixed cylinder 22, thereby achieving a sealing fit between the first fixed cylinder 21 and the second fixed cylinder 22. In addition, the first annular protrusions 215 can maintain a certain distance between the outer wall of the first fixed cylinder 21 and the inner wall of the second fixed cylinder 22, thereby forming a second chamber 220 to facilitate the flow of condensate.

[0067] See Figure 2 and Figure 4 The second fixed cylinder 22 has a second sealing element 24 at one end near the water inlet 110. The outer wall of the second fixed cylinder 22 is sealed to the inner wall of the outer casing 1 through the second sealing element 24. This arrangement prevents condensate entering from the water inlet 110 from flowing into the outside of the second fixed cylinder 22, ensuring that condensate can only enter the first fixed cylinder 21 and be filtered by the filter element 3, further guaranteeing the condensate treatment effect.

[0068] In this embodiment, the second fixed cylinder 22 has two spaced second annular protrusions 227 at one end near the water inlet 110, and a second sealing groove 228 is formed between the two second annular protrusions 227. The second sealing member 24 is engaged in the second sealing groove 228 and makes sealing contact with the inner wall of the outer shell 1, thereby achieving a sealing fit between the second fixed cylinder 22 and the inner wall of the outer shell 1.

[0069] For example, both the first sealing element 23 and the second sealing element 24 are sealing rings, such as O-rings, V-rings, rectangular rings, etc., as long as they can provide a good sealing effect.

[0070] See Figure 2 , Figure 4 and Figure 5 The condensate purification device also includes filter cylinders 4, which are spaced out from the fixed cylinder assembly 2. Specifically, the filter cylinders 4 are spaced out from the second fixed cylinder 22. Condensate flows out through the second water inlet 221 and enters the space between the filter cylinders 4 and the second fixed cylinder 22. The condensate is further filtered by the filter cylinders 4 before entering the outer casing 1, which can further improve the purification effect of the condensate. At the same time, the presence of the filter cylinders 4 can further control the flow rate of the condensate, ensuring that the condensate can fully contact the filter element 3 in the first fixed cylinder 21. For example, the filter cylinder 4 is a filter screen cylinder structure with a filtration accuracy greater than that of the filter element 3.

[0071] See Figure 4 and Figure 5The fixed cylinder assembly 2 is provided with multiple support ribs 224 spaced apart along its circumference. The support ribs 224 can contact the inner wall of the filter cylinder 4. The multiple support ribs 224 can stably support the filter cylinder 4, prevent the filter cylinder 4 from deforming, and maintain a fixed distance between the filter cylinder 4 and the fixed cylinder assembly 2, so as to reserve a certain flow space for condensate water and fully filter the condensate water.

[0072] In this embodiment, multiple support ribs 224 are evenly distributed along the circumferential direction on the outer peripheral wall of the second fixed cylinder 22, which can not only ensure the support stability of the filter cylinder 4, but also uniformly strengthen the structural strength of the second fixed cylinder 22.

[0073] See Figure 2 and Figure 4 Both ends of the second fixed cylinder 22 are provided with third sealing elements 25, and the outer wall of the second fixed cylinder 22 is sealed to the inner wall of the filter cylinder 4 through the third sealing elements 25. This arrangement prevents condensate from directly entering the outer shell 1 from both ends of the filter cylinder 4, ensuring that all condensate is filtered by the filter cylinder 4 before entering the outer shell 1, thus guaranteeing the filtration effect of the condensate.

[0074] In this embodiment, as Figure 2 and Figure 4 As shown, the second fixed cylinder 22 has three second annular protrusions 227 spaced apart at one end near the inlet 110 of the outer casing 1. These three protrusions form two sealing grooves. The upper sealing groove is a second sealing groove 228 for accommodating the second sealing element 24, and the lower sealing groove is defined as a third sealing groove 229 for accommodating the third sealing element 25. The second fixed cylinder 22 has two second annular protrusions 227 spaced apart at one end near the outlet 120 of the outer casing 1. A third sealing groove 229 is formed between the two protrusions, and a third sealing element 25 is installed within this groove. The third sealing elements 25 at both ends of the second fixed cylinder 22 make sealing contact with the inner wall of the filter cylinder 4, achieving a sealed fit between the second fixed cylinder 22 and the inner wall of the filter cylinder 4. Simultaneously, the second annular protrusions 227 also maintain a certain distance between the outer wall of the second fixed cylinder 22 and the inner wall of the filter cylinder 4, facilitating the flow of condensate.

[0075] See Figure 2 , Figure 4 and Figure 5 The condensate purification device also includes a magnetic suction component 5 installed on the fixed cylinder assembly 2. The magnetic suction component 5 is used to attract magnetic substances in the condensate. The magnetic suction component 5 can effectively remove magnetic impurities in the condensate, such as Fe2O3 (rust), Fe3O4 (magnetic iron oxide), and metal wear particles (such as iron filings from water pumps / pipes), preventing magnetic substances from damaging precision components such as water pumps and solenoid valves, reducing the failure rate of gas water heaters, and improving the stability and reliability of use.

[0076] See Figure 2 and Figure 5 The fixed cylinder assembly 2 is provided with an insert groove 225, and the magnetic attractor 5 is embedded in the insert groove 225. In this embodiment, the insert groove 225 is located at the bottom of the second fixed cylinder 22, so that the magnetic attractor 5 can be directly opposite the filter element 3 in the first fixed cylinder 21, which can better adsorb magnetic substances in the condensate.

[0077] Furthermore, the sidewall of the mounting groove 225 is provided with a plurality of limiting ribs 2251 spaced circumferentially. The magnetic attractor 5 is secured in the mounting groove 225 by the limiting ribs 2251, ensuring that the magnetic attractor 5 is securely installed. For example, the magnetic attractor 5 can be a permanent magnet (such as a neodymium magnet) or an electromagnet.

[0078] See Figure 2 , Figure 4 and Figure 5 The fixed cylinder assembly 2 is provided with a support structure 226 at one end near the outlet 120. The support structure 226 can support and abut against the inner wall of the outer shell 1. When the fixed cylinder assembly 2 is installed into the outer shell 1, the top of the fixed cylinder assembly 2 abuts against the inlet 110 side of the outer shell 1, and the bottom of the fixed cylinder assembly 2 abuts against the outlet 120 side of the outer shell 1 through the support structure 226, so that the fixed cylinder assembly 2 is stably fixed in the outer shell 1.

[0079] In this embodiment, the support structure 226 includes a plurality of support pieces spaced circumferentially on the second fixed cylinder 22. After the first fixed cylinder 21 and the second fixed cylinder 22 are assembled, when they are installed into the outer shell 1, the plurality of support pieces abut against the inner circumferential wall of the outer shell 1 on the side near the water outlet 120, so that the fixed cylinder assembly 2 is placed in the center inside the outer shell 1, ensuring that the water inlet end of the fixed cylinder assembly 2 is directly opposite the water inlet 110 of the outer shell 1.

[0080] See Figure 1 , Figure 4 and Figure 5 The outer casing 1 includes a first cylindrical portion 11 and a second cylindrical portion 12. The ends of the first cylindrical portion 11 and the second cylindrical portion 12 facing each other are sleeved together, facilitating assembly and disassembly, thereby making it easy to replace and clean the internal filter cartridge 4 and filter element 3. In this embodiment, the first cylindrical portion 11 is threaded onto the second cylindrical portion 12, ensuring a reliable connection and convenient assembly / disassembly. Furthermore, a fourth sealing element 13 is provided at the sleeve joint of the first cylindrical portion 11 and the second cylindrical portion 12, enabling a sealed connection between the first cylindrical portion 11 and the second cylindrical portion 12 to prevent water leakage. Exemplarily, the fourth sealing element 13 is a sealing ring.

[0081] Furthermore, an anti-slip structure is provided on the outer wall surface of the first cylindrical portion 11 and / or the second cylindrical portion 12 to facilitate the assembly and disassembly of the first cylindrical portion 11 and the second cylindrical portion 12. For example, the anti-slip structure may be anti-slip stripes or anti-slip grooves.

[0082] See Figure 4 and Figure 5 The first cylindrical section 11 has a water inlet connection 111 at the end opposite to the second cylindrical section 12, and the water inlet connection 111 has a water inlet 110. The second cylindrical section 12 has a water outlet connection 121 at the end opposite to the first cylindrical section 11, and the water outlet connection 121 has a water outlet 120. The water inlet connection 111 and the water outlet connection 121 are used to connect to the condensate delivery pipeline 200. Alternatively, the water inlet connection 111 can be directly connected to the condensate outlet of the condenser heat exchanger 100 of the gas water heater, and the water outlet connection 121 can be connected to the condensate delivery pipeline 200.

[0083] Optionally, see Figure 1 and Figure 2 Both the inlet connection 111 and the outlet connection 121 have threaded structures, and the condensate purification device can be connected to the condensate delivery pipeline 200 by screwing the threads, making the connection operation convenient.

[0084] In this embodiment, see Figure 4 and Figure 5 The outer casing 1 has a sealing joint 14 at the outlet 120, which is sealed and inserted into the outlet 120. Specifically, a fifth sealing element 15 is fitted onto the sealing joint 14, and the fifth sealing element 15 makes sealing contact with the wall surface at the outlet 120 to prevent leakage. Further, the sealing joint 14 has a threaded connection portion 141 for connecting to the condensate delivery pipeline 200. Exemplarily, the fifth sealing element 15 is a sealing ring.

[0085] This embodiment also provides a gas water heater, including a condenser heat exchanger 100 and a condensate purification device as described above. The condensate purification device is used to purify the condensate output from the condenser heat exchanger 100. By purifying the condensate generated by the heat exchange in the condenser heat exchanger 100, the condensate is made harmless and easy to discharge or recycle.

[0086] The gas water heater provided in this embodiment has an improved purification effect because the condensate water purification device can effectively remove harmful substances from the condensate water. This ensures that when the condensate water is recycled, for example, when the purified condensate water is fed into the water circuit system of the gas water heater, the output of the gas water heater is clean. This prevents users from harming their skin when using the water, such as for bathing or washing, thus improving water safety.

[0087] See Figure 6The gas water heater also includes an inlet pipe 300, which connects to the heat exchange inlet of the condensing heat exchanger 100. The condensate outlet of the condensing heat exchanger 100 is connected to a condensate delivery pipe 200. A condensate purification device is installed on the condensate delivery pipe 200, which is connected to the inlet pipe 300 to deliver purified condensate to the inlet pipe 300, thus achieving condensate recycling. Alternatively, in other embodiments, the condensate delivery pipe 200 can be connected to the outlet pipe of the gas water heater.
