The numerical values not using the relative terms should also be disclosed as the specific values with tolerances. In addition, "substantially" when expressing the relative angular positional relationship (for example, substantially parallel, substantially perpendicular), can refer to a certain degree (for example, 1 degree, 5 degrees, 10 degrees or more) plus or minus on the basis of the indicated angle.

[0055] In the present utility model, the person skilled in the art will understand that the functions performed by the components can be performed by one component, multiple components, one part, or multiple parts.

[0057] Figure 1 A first view of the wall-mounted stove water system provided by the embodiment is shown. Figure 2 A second view of the wall-mounted stove water system provided by the embodiment is shown. Figures 1-2 As shown in the figure, the embodiment provides a wall-mounted stove water system, which comprises an inlet and outlet water valve group 100, and the inlet and outlet water valve group 100 comprises an integrally formed valve body 1, the valve body 1 comprises a three-way valve part 11, a heat exchange valve part 12 and an inlet water valve part 13, the three-way valve part 11 is located between the heat exchange valve part 12 and the inlet water valve part 13, and the heat exchange valve part 12 and the inlet water valve part 13 are used for connecting a heat exchange structure 200.

[0058] It should be particularly pointed out that, as Figure 1As shown, the height direction of the water inlet and outlet valve group 100 after actual installation is defined as the up-down direction, wherein the side of the water inlet and outlet valve group 100 close to the combustion chamber is defined as up, the side of the water inlet and outlet valve group 100 away from the combustion chamber is defined as down, the side of the water inlet and outlet valve group 100 close to the heat exchange structure 200 is defined as back, and the side of the water inlet and outlet valve group 100 away from the heat exchange structure 200 is defined as front; when a user stands facing the front of the water inlet and outlet valve group 100, the side of the water inlet and outlet valve group 100 toward the right hand of the user is defined as right, and the side of the water inlet and outlet valve group 100 toward the left hand of the user is defined as left. In this embodiment, the height direction of the water inlet and outlet valve group 100 is the up-down direction, the width direction of the water inlet and outlet valve group 100 is the left-right direction, and the thickness direction of the water inlet and outlet valve group 100 is the front-back direction.

[0059] The wall-mounted boiler water system provided by the embodiment simplifies the processing technology, improves the processing efficiency, and can simplify the assembly process of the heat exchange structure 200 and the water inlet and outlet valve group 100, and improve the assembly efficiency, by setting the valve body 1 of the water inlet and outlet valve group 100 as an integrated structure, which only needs to design and process a set of molds during processing. The arrangement space between the heat exchange valve part 12 and the water inlet valve part 13 can be fully utilized by setting the three-way valve part 11 between the heat exchange valve part 12 and the water inlet valve part 13, which greatly reduces the size of the water inlet and outlet valve group 100 exceeding the heat exchange structure 200 in the width direction compared with the prior art, thereby reducing the size of the entire wall-mounted boiler water system in the width direction, and further meeting the miniaturization requirement of the wall-mounted boiler water system.

[0060] Figure 3 The structure schematic diagram of the heat exchange structure 200 provided by the embodiment is shown. Figure 4 The first view of the water inlet and outlet valve group 100 provided by the embodiment is shown. As shown in the figure, Figures 3-4 and combined with Figure 2As shown, the heat exchange structure 200 includes heat exchange matched heat exchange channels (not shown in the figure) and water supply channels (not shown in the figure), the three-way valve part 11 includes a hot water inlet 111 and a heating channel 112, the heat exchange valve part 12 has a first heat exchange inlet channel 121, a first heat exchange outlet channel 122 and a bathroom channel 123, the hot water inlet 111 is connected with a hot water outlet of the combustion chamber, and the hot water inlet 111 can selectively communicate with the heating channel 112 or the first heat exchange inlet channel 121, the first heat exchange inlet channel 121 and the first heat exchange outlet channel 122 are connected with a heat exchange inlet 2011 of the heat exchange channel and a water supply outlet 2022 of the water supply channel respectively, the first heat exchange outlet channel 122 is connected with the bathroom channel 123, and the first heat exchange outlet channel 122 and the bathroom channel 123 are connected; the water inlet valve part 13 has a water inlet interface 131, a second heat exchange inlet channel 133, a second heat exchange outlet channel 134 and a water pump interface 132, the water inlet interface 131 is connected with an external water source, the second heat exchange outlet channel 134 is connected with the water pump interface 132, the second heat exchange inlet channel 133 is connected with the water inlet interface 131, and the second heat exchange inlet channel 133 and the second heat exchange outlet channel 134 are connected with a water supply inlet 2021 of the water supply channel and a heat exchange outlet 2012 of the heat exchange channel respectively, and the water pump interface 132 is connected with a cold water inlet of the combustion chamber through a water supply pump (not shown in the figure).

[0061] In work, when the hot water inlet 111 is connected with the heating channel 112, the hot water heated by the combustion chamber can flow to the heating system through the hot water inlet 111 and the heating channel 112 to provide heating demand for users, and the water in the heating system which is heat exchanged with the outside can flow to the combustion chamber through the water inlet valve part 13 to be heated again, thereby forming a heating water circulation loop; when the hot water inlet 111 is connected with the first heat exchange inlet channel 121, the hot water heated by the combustion chamber can flow to the heat exchange channel of the heat exchange structure 200 through the hot water inlet 111 and the first heat exchange inlet channel 121, and then flow to the second heat exchange outlet channel 134 of the water inlet valve part 13 after heat exchanged with the water in the water supply channel, and then flow back to the combustion chamber through the water pump interface 132 to be heated again, thereby forming a heat exchange circulation loop; the water in the external water source can flow into the water supply channel of the heat exchange structure 200 through the water inlet interface 131 and the second heat exchange inlet channel 133, and then flow to the bathroom system through the first heat exchange outlet channel 122 of the heat exchange valve part 12 and the bathroom channel 123 after heat exchanged with the water in the heat exchange channel, to provide domestic water for users.

[0062] It needs to be explained that the heating system specifically refers to the terminal heat dissipation components such as heating radiators, floor heating pipes or fan coil units, and the water heated in the combustion chamber can be pumped into the above-mentioned terminal heat dissipation components through the water inlet and outlet valve group 100, and the heat is dissipated to the indoor air in the form of heat dissipation, so as to improve the indoor environment temperature, so as to meet the heating needs of the user. The bathroom system specifically refers to the water device used by the user for showering, washing and other operations. Therefore, the heating system and the bathroom system are relatively mature technologies in the art, and the specific structure of the heating system and the bathroom system will not be described here.

[0063] It needs to be explained that the combustion chamber is a relatively mature technology in the art, and the specific structure of the combustion chamber will not be described here.

[0064] In order to ensure the sealing performance of the waterway connection between the heat exchange valve part 12 and the heat exchange structure 200 and between the water inlet valve part 13 and the heat exchange structure 200, sealing members are arranged between the outlet of the first heat exchange inlet flow channel 121 and the heat exchange inlet 2011, between the inlet of the first heat exchange outlet flow channel 122 and the water supply outlet 2022, between the outlet of the second heat exchange inlet flow channel 133 and the water supply inlet 2021, and between the inlet of the second heat exchange outlet flow channel 134 and the heat exchange outlet 2012, so as to avoid leakage at each connection position and affect the use safety of the entire wall-mounted stove waterway system. Optionally, the sealing member can be an O-ring or a star-shaped ring. The specific number of sealing members at each connection position is not limited in the embodiment, and the designer can adjust the specific number of sealing members according to actual needs.

[0065] Figure 5 A first sectional view of the water inlet and outlet valve group 100 provided in the embodiment is shown. As shown in Figure 5 and in combination with Figure 4 It is shown that the three-way valve part 11 also has a three-way valve cavity 110, which includes a first cavity 1102, a main valve cavity 1101 and a second cavity 1103 which are sequentially communicated along the axial direction thereof, the main valve cavity 1101 is communicated with the hot water inlet 111, and the main valve cavity 1101 can selectively communicate the first cavity 1102 or the second cavity 1103; the heating channel 112 is communicated with the first cavity 1102, and the first heat exchange inlet flow channel 121 is communicated with the second cavity 1103. When the main valve cavity 1101 is communicated with the first cavity 1102, the hot water in the combustion chamber can be circulated in the heating water circulation loop; when the main valve cavity 1101 is communicated with the second cavity 1103, the hot water in the combustion chamber can be circulated in the heat exchange circulation loop.

[0066] Optionally, the inlet / outlet valve assembly 100 further includes a switching mechanism 2, which is movably disposed in the three-way valve chamber 110 to selectively connect the three-way valve chamber 110 to the heating channel 112 or the first heat exchange inlet channel 121. That is, through the movement of the switching mechanism 2 in the three-way valve chamber 110, the passage between the main valve chamber 1101 and the first chamber 1102, or the passage between the main valve chamber 1101 and the second chamber 1103, can be selectively opened, thereby achieving three-way switching. This embodiment will not elaborate on the specific structure and working principle of the switching mechanism 2. Switching mechanisms applicable to inlet / outlet valve assemblies to achieve three-way switching in the three-way valve chamber are all within the protection scope of this embodiment.

[0067] Furthermore, the inlet and outlet valve assembly 100 also includes a drive mechanism (not shown in the figure), the output end of which is connected to the switching mechanism 2 to drive the switching mechanism 2 to move within the three-way valve chamber 110. In this embodiment, the drive mechanism may be a synchronous motor, a stepper motor, a servo motor, or other drive devices.

[0068] like Figure 1 and Figure 2 As shown, the heat exchange valve section 12 also has a first interface 1201, and a first plug (not shown in the figure) is detachably connected to the first interface 1201. The design of the first interface 1201 facilitates the processing of each flow channel within the heat exchange valve section 12, thereby simplifying the manufacturing process. In actual use, installing the first plug at the first interface 1201 can prevent water leakage from the inlet / outlet valve assembly 100 through the first interface 1201. In other embodiments, an expansion tank (not shown in the figure) can also be connected to the first interface 1201 to maintain the water pressure balance of the heating system. When an expansion tank needs to be installed, the operator can remove the first plug at the first interface 1201 and then connect the corresponding expansion tank to the first interface 1201. The expansion tank is a relatively mature technology in this field, and the specific structure and working principle of the expansion tank will not be described in detail in this embodiment.

[0069] Optionally, the heat exchange valve section 12 further includes a second interface 1202, which is connected to the first heat exchange inlet channel 121. The second interface 1202 is used to install a pressure detection element to detect the current pressure of the water in the first heat exchange inlet channel 121, and to control the opening and closing of other components based on the current pressure value, thereby ensuring the normal operation of the entire wall-hung boiler water system. Of course, in other embodiments, a pressure detection element may not be installed at the second interface 1202. When a pressure detection element is not installed at the second interface 1202, a second plug must be installed at the second interface 1202 to prevent water leakage from the inlet / outlet valve assembly 100 through the second interface 1202.

[0070] Optionally, the heat exchange valve section 12 also has a third interface 1203, which is connected to the bathroom passage 123. The third interface 1203 is used to install a temperature detection element to detect the current water temperature in the bathroom passage 123, and to control the inlet water flow rate according to the current water temperature, so as to ensure that the user can obtain domestic water at a suitable temperature and improve the user experience. Of course, in other embodiments, the temperature detection element may not be installed at the third interface 1203. When the temperature detection element is not installed at the third interface 1203, a third plug needs to be installed at the third interface 1203 to prevent water in the inlet / outlet valve assembly 100 from leaking from the third interface 1203.

[0071] In related technologies, the outlet valve is fixed to the heat exchange structure by a first fastener, and the inlet valve is fixed to the heat exchange structure by a second fastener. This design results in only one connection point between the outlet valve and the heat exchange structure, as well as between the inlet valve and the heat exchange structure. In actual use, the outlet valve and the inlet valve can easily rotate around their respective connection points, resulting in poor connection stability. In severe cases, this can lead to displacement or detachment of the corresponding seals, affecting the safety of the wall-hung boiler water system.

[0072] To solve the above problems, such as Figures 1-3 As shown, in this embodiment, the heat exchange valve part 12 is provided with a first connecting hole 124, and the heat exchange structure 200 is provided with a second connecting hole 2031 corresponding to the first connecting hole 124. The first fastener (not shown in the figure) is sequentially inserted into the first connecting hole 124 and the second connecting hole 2031. The water inlet valve part 13 is provided with a third connecting hole 135, and the heat exchange structure 200 is provided with a fourth connecting hole 2032 corresponding to the third connecting hole 135. The second fastener (not shown in the figure) is sequentially inserted into the third connecting hole 135 and the fourth connecting hole 2032. Since the valve body 1 of the inlet and outlet water valve group 100 in this embodiment is an integrally formed structure, the above-mentioned arrangement allows the valve body 1 to be fixed to the heat exchange structure 200 by two fasteners, thereby increasing the number of connection points and improving the stability of the connection between the heat exchange structure 200 and the inlet and outlet water valve group 100. This prevents the inlet and outlet water valve group 100 from rotating or shifting during use, thereby ensuring the sealing of the water circuit connection between the heat exchange structure 200 and the inlet and outlet water valve group 100, preventing leakage between the two, and ensuring the safety of the entire wall-hung boiler water circuit system.

[0073] In this embodiment, the first fastener is a first fastening bolt, and at least one of the first connecting hole 124 and the second connecting hole 2031 is a threaded hole; the second fastener is a second fastening bolt, and at least one of the third connecting hole 135 and the fourth connecting hole 2032 is a threaded hole. Bolted connections have the advantages of tight connection and easy disassembly and assembly, so as to achieve a stable connection between the inlet and outlet water valve assembly 100 and the heat exchange structure 200.

[0074] Figure 6 A second view of the water inlet and outlet valve set 100 is shown. Figure 7 A partial cross-sectional view of the water inlet and outlet valve set 100 is shown. Figure 8 A structural schematic diagram of the magnetic rotor 31 is shown. As Figures 6-8 shown, the water inlet and outlet valve set 100 further comprises a water flow sensor 3, and the water inlet valve part 13 further has a water inlet channel 130, an inlet of the water inlet channel 130 forms the water inlet interface 131, and the water flow sensor 3 is configured to detect the water flow in the water inlet channel 130, so as to accurately control the water flow, thereby ensuring that the water flowing out of the bathroom channel 123 is at a suitable temperature and meets the user's water demand.

[0075] In this embodiment, the water flow sensor 3 comprises a magnetic rotor 31 and a Hall element 32, the magnetic rotor 31 is installed in the water inlet channel 130 and can rotate under the impact of the water flow flowing into the water inlet channel 130, the rotation axis of the magnetic rotor 31 coincides with the axis of the water inlet channel 130, and the Hall element 32 is arranged on the water inlet valve part 13 and is signal connected with the magnetic rotor 31. When the water flow at the water inlet interface 131 enters the water inlet channel 130, the water flow impacts the magnetic rotor 31 to make it rotate, thereby generating a periodically changing magnetic field, and the Hall element 32 generates a pulse signal by detecting the change of the magnetic field, and the current water flow can be obtained by calculating the pulse frequency, which is simple in structure and can ensure the accuracy of the detection result. By coinciding the rotation axis of the magnetic rotor 31 with the axis of the water inlet channel 130, the size of the installation space (i.e. the water inlet channel 130) for installing the magnetic rotor 31 in the thickness direction of the valve body 1 can be reduced, thereby optimizing the spatial layout of the water inlet valve part 13 and further meeting the miniaturization requirement of the wall-hanging stove water system.

[0076] It should be explained that, as Figure 6 and Figure 7 shown, in this embodiment, the water inlet interface 131 is arranged downward, the second heat exchange inlet channel 133 and the second heat exchange outlet channel 134 are arranged rearward (i.e. toward the side of the heat exchange structure 200) and along the up-down direction; the axis direction of the water inlet channel 130 extends along the up-down direction, and no additional installation cavity for installing the magnetic rotor 31 is needed, thereby simplifying the overall structure of the water inlet and outlet valve set 100.

[0077] Specifically, as Figure 7 and Figure 8As shown, the magnetic rotor 31 comprises a magnetic axle 311, a sleeve 312 and guide vanes 313, the axis of the magnetic axle 311 coincides with the axis of the water inlet channel 130; the sleeve 312 is installed on the magnetic axle 311; a plurality of guide vanes 313 are arranged in the sleeve 312 along the circumference of the magnetic axle 311, the guide vanes 313 have guide surfaces 3131 which are arranged obliquely relative to the axis of the magnetic axle 311. By arranging the guide surfaces 3131 which are oblique relative to the axis of the magnetic axle 311, the water flow flowing into the water inlet channel 130 can directly impact on the guide surfaces 3131 to push the magnetic rotor 31 to rotate, thereby ensuring the accuracy of the current water flow detected by the water flow sensor 3. Optionally, the guide surfaces 3131 are arc surfaces, which can make the guide vanes 313 more easily rotate under the impact of the water flow, so as to avoid that the water flow sensor 3 cannot accurately detect the current water flow when the water flow is small.

[0078] Further, the magnetic rotor 31 further comprises rotating vanes 314, a plurality of rotating vanes 314 are arranged in the sleeve 312 along the circumference and / or axis of the magnetic axle 311 and are located downstream of the guide vanes 313. In the embodiment, the rotating vanes 314 are flat plate vanes, which cooperate with the guide vanes 313, the arrangement of the rotating vanes 314 can reduce the processing difficulty and processing cost of the magnetic rotor 31, and the arrangement of the guide vanes 313 can make the magnetic rotor 31 rotate under the impact of the water flow to accurately obtain the current water flow value.

[0079] Figure 9 A second sectional view of the water inlet and outlet valve set 100 provided by the embodiment is shown. As shown in the figure, Figure 9 and in combination Figure 4 As shown, the water inlet valve part 13 further has a water supplement channel 1361 and a communication port 1362 which can communicate the water supplement channel 1361 and the water inlet channel 130, the water supplement channel 1361 communicates with the water pump interface 132; the water inlet and outlet valve set 100 further comprises a water supplement valve 4 which can selectively open and close the communication port 1362. When the heating water circuit is short of water, the water supplement valve 4 can be adjusted to open the communication port 1362, so that the water in the water inlet channel 130 flows to the water supplement channel 1361 through the communication port 1362 and then flows to the water pump interface 132 to be delivered to the combustion chamber by the water pump for heating, thereby supplementing water for the heating water circuit. The specific structure and working principle of the water supplement valve 4 are not limited in the embodiment, and the water supplement valve which can be applied to the water inlet valve in the related art is within the protection scope of the embodiment.

[0080] In the related art, in order to realize water pressure balance of the entire wall-mounted boiler water system, the water outlet valve also has a bypass flow channel. When the bypass flow channel is opened, the water in the heating channel will flow to the heat exchange structure through the first heat exchange inlet channel, and then flow to the combustion chamber from the water pump interface of the water inlet valve to complete the water replenishment operation. However, in this water replenishment process, on the one hand, the water flowing into the heat exchange structure will exchange heat with the bathroom water therein, resulting in heat loss. When the heat-exchanged water flows into the combustion chamber to be reheated, the heating time is relatively long, which will cause resource waste. On the other hand, the water flowing from the heating channel to the heat exchange structure has a high temperature. When the bathroom water in the heat exchange structure has a low temperature, the sealing element at the connection between the water outlet valve and the heat exchange structure is prone to rapid temperature rise, which will cause rapid expansion of the sealing element and exist a leakage risk.

[0081] Figure 10 A third sectional view of the water inlet and outlet valve set 100 provided by the present embodiment is shown. To solve the above problems, as shown in Figure 10 and shown in Figure 1 , Figure 2 , the valve body 1 further includes a bypass valve part 14, the two ends of the bypass valve part 14 are connected with the three-way valve part 11 and the water inlet valve part 13 respectively, and a bypass flow channel 141 is formed in the bypass valve part 14. The bypass flow channel 141 can selectively communicate the heating channel 112 and the second heat exchange outlet channel 134. By providing the bypass valve part 14, when the main valve cavity 1101 is in communication with the heating channel 112, the bypass flow channel 141 can communicate the heating channel 112 and the second heat exchange outlet channel 134, so that the water in the heating channel 112 flows to the combustion chamber through the bypass flow channel 141 and then through the second heat exchange outlet channel 134 and the water pump interface 132 in sequence, thereby stabilizing the water pressure balance of the entire wall-mounted boiler water system, and further ensuring the safe use of the wall-mounted boiler water system. In addition, the water in the heating channel 112 does not need to exchange heat with the heat exchange structure 200, which can shorten the time required for reheating by the combustion chamber, reduce resource waste, and avoid the rapid expansion of the sealing element caused by the heat exchange between the water with high temperature in the heating channel 112 and the water with low temperature in the heat exchange structure 200, thereby ensuring the safety of the wall-mounted boiler water system.

[0082] Figure 11 A structure schematic view of the one-way assembly 5 provided by the present embodiment is shown. Figure 12 A sectional view schematic view of the one-way assembly 5 provided by the present embodiment is shown. As shown in Figures 11-12 and shown in Figure 10As shown, the water inlet and outlet valve group 100 further comprises a one-way assembly 5, which comprises a one-way valve 51 and a bypass plug 52. The one-way valve 51 is adjustably installed in the bypass flow channel 141 to allow water in the heating channel 112 to flow to the water pump interface 132 only. The bypass valve portion 14 is provided with a bypass opening in communication with the bypass flow channel 141, and the bypass plug 52 is sealingly plugged in the bypass opening. By providing the one-way valve 51, water in the water inlet valve portion 13 can be prevented from flowing back into the three-way valve portion 11, affecting the quality of the bathroom water. The provision of the bypass opening can facilitate the machining of the bypass flow channel 141 on the bypass valve portion 14, thereby simplifying the machining process and reducing the machining difficulty. The provision of the bypass plug 52 can prevent water in the bypass flow channel 141 from leaking from the bypass opening.

[0083] Specifically, the one-way valve 51 comprises a valve seat 511, a valve core 512 and a spring 513. The valve seat 511 is sealingly installed in the bypass flow channel 141 and has a valve opening 5111 therein. The valve core 512 is movably arranged in the valve seat 511, and the spring 513 is connected to the valve seat 511 and the valve core 512 at two ends thereof. The valve core 512 can block the valve opening 5111 under the elastic action of the spring 513. Optionally, a sealing gasket 514 is further provided on the side of the valve core 512 facing the valve opening 5111 to improve the sealing performance of the valve core 512 in the sealing position. The one-way valve is a commonly used valve structure in the prior art, and the working principle of the one-way valve 51 will not be described herein.

[0084] In the present embodiment, since the bypass valve portion 14 is used to connect the three-way valve portion 11 and the water inlet valve portion 13, the bypass flow channel 141 in the bypass valve portion 14 is relatively long, making it inconvenient to install the one-way valve 51. To solve this problem, in the present embodiment, the one-way assembly 5 further comprises a connecting rib 53, which is connected to the valve seat 511 and the bypass plug 52 at two ends thereof. That is, the operator only needs to hold the bypass plug 52 and insert the one-way valve 51 into the bypass flow channel 141 by aligning the bypass plug 52 with the bypass opening, which is relatively simple and can achieve rapid installation of the one-way valve 51.

[0085] Optionally, the bypass plug 52, the connecting rib 53 and the valve seat 511 are integrally formed, which saves the connecting structure between the bypass plug 52, the connecting rib 53 and the valve seat 511, thereby reducing the number of parts, simplifying the assembly process, facilitating installation, and improving the overall strength of the one-way assembly 5. Of course, in other embodiments, the bypass plug 52 and the connecting rib 53, and the connecting rib 53 and the valve seat 511 can also be connected by fasteners, which can also achieve the above effects.

[0086] As shown in FIG. 1, the water inlet and outlet valve group 100 comprises a three-way valve portion 11, a bypass valve portion 14 and a water inlet valve portion 13. The three-way valve portion 11 is connected to the bypass valve portion 14 and the water inlet valve portion 13, and is provided with a heating channel 112 and a water pump interface 132. The bypass valve portion 14 is connected to the three-way valve portion 11 and the water inlet valve portion 13, and is provided with a bypass flow channel 141 and a bypass opening. The water inlet valve portion 13 is connected to the bypass valve portion 14 and is provided with a water inlet channel 131 and a water inlet opening. Figure 11As shown, in the present embodiment, the number of connecting ribs 53 is two, and the two connecting ribs 53 are symmetrically arranged on the two sides of the bypass plug 52, and the gap between the two connecting ribs 53 can allow the water in the bypass flow channel 141 to pass. In this way, the stability of the connection between the bypass plug 52 and the valve seat 511 can be improved without affecting the water flow in the bypass flow channel 141. Of course, in other embodiments, the number of connecting ribs 53 can also be adjusted according to actual conditions, and the present embodiment is not limited in this regard.

[0087] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
