[0003] Currently, the water inlet of wall-hung boilers is generally directly connected to the municipal water supply pipe. Although tap water is purified and sterilized by the water treatment plant, the water supply pipeline is long, and the municipal water supply pipeline also needs to be connected to the household pipeline before being delivered to the wall-hung boiler. During this process, the tap water may be re-contaminated. In addition, the hardness of water sources varies in different regions. Tap water with higher hardness will produce more scale, which can clog the pipes of the wall-hung boiler. Furthermore, tap water does not contain strontium and selenium, which have health benefits for human skin, and cannot meet the current users' needs for healthy bathing.
[0004] Therefore, a new type of wall-hung boiler equipment needs to be designed. Utility Model Content

Detailed Implementation
[0036] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.
[0037] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.
[0038] This utility model embodiment provides a water valve assembly 1, which includes a water valve housing 10, a water inlet interface 20, a water outlet interface 30, and a filter media assembly 40;
[0039] A cavity 1001 is formed inside the water valve housing 10, and a water flow channel 1002 connecting the water inlet 20 and the water outlet 30 is formed inside the water valve housing 10. It can be understood that the water flow channel 1002 connecting the water inlet 20 and the water outlet 30 can be provided with multiple water inlet 20 and multiple water outlet 30. That is, the water flow channel 1002 inside the water valve housing 10 can be used with multiple flow directions and multiple segments to adapt to different usage scenarios. For example, if it is only used for bathroom or domestic water use, only one water inlet 20 and one water outlet 30 can be provided; when domestic water use, bathroom water use, and heating equipment water use are required, there can be multiple water outlets 30.
[0040] A mounting groove 1003 is provided on the water valve housing 10. The mounting groove 1003 is connected to the cavity 1001 and is located on the water flow channel 1002 between the water inlet 20 and the water outlet 30. The filter media assembly 40 is located in the mounting groove 1003 and is detachably connected to the water valve housing 10. It can be understood that the mounting groove 1003 extends from the outside of the water valve housing 10 to the inside of the cavity 1001. The mounting groove 1003 is used to install the filter media assembly 40 on the water valve housing 10 and connect it to the water flow channel 1002. In this way, the water flows through the filter media assembly 40 before flowing out of the water valve housing 10, so as to filter or treat the water. The detachable connection between the filter media assembly 40 and the water valve housing 10 through the mounting groove 1003 facilitates the cleaning of the water valve housing 10 and the replacement of the filter media assembly 40, which enhances the applicability and extends the service life of the water valve assembly 1.
[0041] In this embodiment, the filter media assembly 40 includes filter media 4001, filter media housing 4002 and plug 4003. The filter media housing 4002 forms a receiving cavity 4004, and the filter media 4001 is disposed in the receiving cavity 4004.
[0042] The plug 4003 is disposed within the mounting groove 1003 and detachably connected to the water valve housing 10. One end of the plug 4003 facing the cavity 1001 of the water valve housing 10 is open to form a mounting cavity 4005. The filter media shell 4002 is disposed within the mounting cavity 4005 and extends outward from the cavity 1001. It can be understood that the plug 4003 is a single-sided open component, with the open side recessed to form the mounting cavity 4005. The open end of the plug 4003 is used to insert into the mounting groove 1003. The first end of the filter media shell 4002 is disposed within the mounting cavity 4005, while the second end protrudes relative to the end face of the plug 4003. That is, the second end of the filter media shell 4002 extends into the cavity 1001 of the water valve housing 10, which is the water flow channel 1002, so that the flowing water needs to pass through the filter media shell 4002, thereby ensuring a higher contact area and thus achieving a better effect.
[0043] In addition, the filter media housing 4002 has multiple through holes 4006 at one end facing the cavity 1001. The through holes 4006 connect the receiving cavity 4004 of the filter media housing 4002 and the cavity 1001 of the water valve housing 10. The through holes 4006 can be set on the end face of the second end of the filter media housing 4002, or they can be set at multiple positions at the end of the second end, including the side and the end face. In this way, the flowing water can enter the filter media housing 4002 through the through holes 4006 and come into contact with the filter media 4001, thus ensuring the treatment effect of the filter media 4001.
[0044] In a preferred embodiment, a first groove 4007 is provided on the outer wall of the plug 4003, and a slot 4008 matching the first groove 4007 is provided on the outer wall of the mounting groove 1003 of the water valve housing 10. The water valve assembly 1 also includes a pin 4009. When the plug 4003 is inserted into the mounting groove 1003, the first groove 4007 and the slot 4008 are positioned correspondingly, and the pin 4009 is inserted into the slot 4008 and the first groove 4007 to fix the plug 4003 and the water valve housing 10. As can be understood, the first groove 4007 can be a groove surrounding the outer wall of the plug 4003, or it can be a groove recessed only at a fixed position. The water valve housing 10 has a corresponding slot 4008 on the outer wall of the mounting groove 1003. The slot 4008 is through. When the plug 4003 is inserted into the mounting groove 1003, the first groove 4007 and the slot 4008 correspond to each other to form a through channel. The pin 4009 can pass through this channel to connect and fix the plug 4003 and the water valve housing 10. Furthermore, the first groove 4007 surrounds the outer wall of the plug 4003, and there are two slots 4008. The pin 4009 is a U-shaped pin 4009. After the first groove 4007 and the slot 4008 are aligned, two channels are formed. The U-shaped pin 4009 can be inserted and fixed. The two fixing points can further ensure the connection strength between the plug 4003 and the water valve housing 10. When it is necessary to remove the plug 4003, it is only necessary to pull out the U-shaped pin 4009 directly. There is no need to use additional tools such as screwdrivers or wrenches, making it more convenient and simple to use.
[0045] And / or,
[0046] The outer wall of the plug 4003 is provided with at least one second groove 4010, and a sealing ring 4011 is provided on the second groove 4010. When the plug 4003 is inserted into the mounting groove 1003, the sealing ring 4011 is interference-fitted with the inner wall of the mounting groove 1003. It can be understood that when the sealing ring 4011 is fitted onto the second groove 4010, the outer surface of the sealing ring 4011 protrudes relative to the second groove 4010. When the plug 4003 is inserted into the mounting groove 1003, the sealing ring 4011 can tightly contact the inner wall of the mounting groove 1003, thereby providing a high degree of sealing.
[0047] In this embodiment, the filter media 4001 is one of strontium-rich filter media 4001, selenium-rich filter media 4001, strontium- and selenium-rich filter media 4001, or scale-inhibiting filter media 4001. Strontium and selenium are beneficial to human skin. By treating the water through the filter media assembly 40, the water flowing out of the water valve assembly 1 can contain strontium and selenium, meeting the user's requirements for healthy bathing. If the filter media assembly 40 is equipped with scale-inhibiting material, it can absorb minerals in the water to reduce the hardness of the water. Especially for the heating circulating water system of a wall-hung boiler, minerals in the heated water are prone to form solid precipitates, which can clog the pipes. During the heating circulating water process, passing through the scale-inhibiting water valve assembly 1 can greatly reduce scale formation, thereby reducing energy consumption and the probability of equipment damage.
[0048] In this embodiment, the water valve assembly 1 further includes a temperature probe 1004. A temperature measuring interface 1005 is provided on the water valve housing 10, and the temperature measuring interface 1005 is connected to the water flow channel 1002. One end of the temperature probe 1004 extends into the temperature measuring interface 1005 to measure the water temperature in the water flow channel 1002; and / or,
[0049] The water valve assembly 1 also includes a water pressure probe 1006. A pressure measuring interface 1007 is provided on the water valve housing 10. The pressure measuring interface 1007 is connected to the water flow channel 1002. One end of the water pressure probe 1006 extends into the pressure measuring interface 1007 to measure the water pressure in the water flow channel 1002.
[0050] In a preferred embodiment, the water valve assembly 1 is an inlet valve, and a water replenishment valve assembly 1008 is provided inside the water valve housing 10. The water outlet 30 includes a first heating water outlet 300130 and / or a second heating water outlet 300230. The water replenishment valve assembly 1008 is located on the side of the water flow channel 1002 near the first heating water outlet 300130 and / or the second heating water outlet 300230, and is used to control the opening / closing of the first heating water outlet 300130 and / or the second heating water outlet 300230. Understandably, the water supply valve is connected to the first heating water outlet 300130 and the second heating water outlet 300230. The first heating water outlet 300130 can be used to connect to a plate heat exchanger, and the second heating water outlet 300230 can be connected to a heating pump to generate heating water. When water enters the water flow channel 1002 from the inlet 20, the water supply valve assembly 1008 opens, and some water flows to the first heating water outlet 300130 and the second heating water outlet 300230. This section of the water flow channel 1002 is the heating water supply channel. In this embodiment, the water pressure probe 1006 is installed in the heating water supply channel to detect the water pressure in the heating water supply channel. When the heating water pressure reaches a preset value, the water supply valve assembly 1008 is closed, and the water can no longer flow to the first heating water outlet 300130 and the second heating water outlet 300230, thus forming a heating water circulation.
[0051] In this preferred embodiment, the water valve assembly 1 further includes a water pump assembly 1009, which is disposed at one end of the water valve housing 10. The water outlet 30 also includes a first bathroom water outlet 300330. The water pump assembly 1009 is connected to the first bathroom water outlet 300330 to form a bathroom channel 1010. The filter media assembly 40 is disposed on the bathroom channel 1010 and is connected to the bathroom channel 1010, so that the water flowing through the water pump assembly 1009 passes through the filter media assembly 40 and flows out from the first bathroom water outlet 300330. It can be understood that the water pump assembly 1009 is used to pressurize the water flow. The water flow enters the water valve housing 10 from the water inlet 20, first enters the water pump assembly 1009 for pressurization, then the water flow passes through the filter media assembly 40 for treatment, and finally flows out from the first bathroom water outlet 300330, thereby realizing the separation of bathroom water and heating water, and simultaneously realizing the treatment or descaling of bathroom water. The water valve assembly 1 of this preferred embodiment has a compact structure.
[0052] In another preferred embodiment, the water valve assembly 1 is an outlet valve. The inlet port 20 includes a heating water port 2001, and the outlet port 30 includes a first heating water outlet port 300130 and a second heating water outlet port 300230. The heating water port 2001 is connected to the first heating water outlet port 300130 and the second heating water outlet port 300230 respectively and distributed to form a first heating circulation channel 1011 and a second heating circulation channel 1012. The first heating circulation channel 1011 and the second heating circulation channel 1012 are connected by a bypass valve 1013. It can be understood that the outlet valve is connected to the rear section of the wall-hung boiler, and the water entering the outlet valve has already been heated. The heated water enters the water valve housing 10 from the heating water inlet 2001 and flows to the first heating water outlet 300130 and the second heating water outlet 300230 respectively. The first heating water outlet 300130 and the second heating water outlet 300230 have different diameters. The first heating water outlet 300130 can be set to be larger, so the first heating circulation channel 1011 is the heating large circulation channel, in which the water flow is larger; the second heating water outlet 300230 has a smaller diameter, so the second heating circulation channel 1012 is the heating small circulation channel.
[0053] The water valve assembly 1 also includes a motor assembly 1014, which is located at one end near the heating water interface 2001 and is used to control the water flow to the first heating circulation channel 1011 and / or the second heating circulation channel 1012. The motor assembly 1014 controls the water flow direction. To prevent the first heating circulation channel 1011 from becoming clogged, leading to poor circulation or even overheating due to dry burning, a bypass valve 1013 is provided to allow water from the second heating circulation channel 1012 to flow to the first heating circulation channel 1011, ensuring equipment safety. In this preferred embodiment, a water pressure probe 1006 can be installed in the second heating circulation channel 1012 to monitor the water pressure in the second heating circulation channel 1012 in real time, determining whether the pressure of the entire heating circulation is appropriate, further ensuring equipment safety.
[0054] In this preferred embodiment, the water inlet 20 further includes a bathroom water inlet 2002, and the water outlet 30 further includes a first bathroom water outlet 300330. The bathroom water inlet 2002 and the first bathroom water outlet 300330 are connected to form a bathroom channel 1010. The filter media assembly 40 is connected to the bathroom channel 1010, so that water flows through the filter media assembly 40 and then flows out from the first bathroom water outlet 300330. It can be understood that the heated water enters the water valve housing 10 from the bathroom water inlet 2002, is filtered or treated by the filter media assembly 40, and then flows out through the first bathroom water outlet 300330, which makes the bathroom water more suitable for the user's needs.
[0055] In addition, in this preferred embodiment, when the water valve assembly 1 is a water outlet valve, the bathroom water interface 2002 and the first bathroom water outlet interface 300330 form a bathroom channel 1010, and the heating water interface 2001, the first heating water outlet interface 300130, and the second heating water outlet interface 300230 form a first heating circulation channel 1011 and a second heating circulation channel 1012. The bathroom channel 1010 and the first heating circulation channel 1011 and the second heating circulation channel 1012 can be set to be non-connected to avoid the circulating water directly contaminating the bathroom water. However, since the bathroom channel 1010 and the first heating circulation channel 1011 and the second heating circulation channel 1012 are all set in the same water valve assembly 1, the circulating water can be used to reheat or keep the bathroom water warm, thereby improving the user experience.
[0056] This utility model also provides a wall-hung boiler, which includes a heat exchange component, a water circulation control component, a circuit control component, and a water valve assembly 1 as described above. The water valve assembly 1 is connected to the heat exchange component through the water circulation control component, and the water valve assembly 1 is also electrically connected to the circuit control component for controlling water outlet or water inlet.
