Description

Technical Field

[0001] This utility model belongs to the technical field of heating and hot water boiler equipment, specifically relating to a water valve assembly with a dual-channel structure and a wall-mounted boiler. Background Technology

[0002] Wall-hung boilers are composite heat source devices that combine heating and hot water functions. They can provide circulating hot water for heating systems and domestic hot water for users, offering an integrated solution and a good user experience.

[0003] However, most wall-hung boilers currently cannot adjust the water flow rate in the bathroom. They can only achieve the water temperature rise by changing the combustion load, which takes a long time. Some products use a water servo structure to adjust the water flow rate in the bathroom, but the water servo structure is large, resulting in a large overall size of the wall-hung boiler and a high cost of water servo. This will cause the following problems: (1) After the bathroom is turned on, if the water flow rate is large or the water pressure is too high, it will result in a long waiting time for hot water or the bathroom water temperature will not rise; (2) When the boiler is turned off and then turned on again during the bathroom, the temperature drop is large when the water is turned off, which affects the bathroom experience.

[0004] Therefore, a new type of wall-hung boiler equipment needs to be designed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a water valve assembly with a reasonable structure and a shortened hot water waiting time through a dual-channel structure, and a wall-mounted boiler using the water valve assembly with the dual-channel structure.

The shut-off valve assembly can connect or disconnect the first water flow channel and the water outlet channel.

[0014] Preferably, the shut-off valve assembly has a movable valve body on the side facing the partition channel wall, and the side of the valve body facing the partition channel wall is the shut-off valve sealing end face;

[0015] When the valve body moves toward the partition channel wall and the sealing end face of the shut-off valve abuts against the partition channel wall, the shut-off valve assembly seals the water outlet channel;

[0016] When the valve body moves away from the partition channel wall, a third water flow channel is formed between the first water flow channel and the outlet channel, and the third water flow channel connects the first water flow channel and the outlet channel.

[0018] When the shut-off valve assembly seals the water outlet channel, water flows from the first water flow channel through the second water flow channel to the water outlet channel. Part of the water flow in the water outlet channel enters the shut-off valve cavity through the water passage, so that the water pressure in the shut-off valve cavity is balanced with that in the water outlet channel.

The first water flow channel is divided into two parts, which are connected to the second and third water flow channels respectively. The first and second water flow channels are configured as normally open channels. A shut-off valve assembly is installed on the third water flow channel, making the first and third water flow channels controllable.

Detailed Implementation

[0035] 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.

[0036] 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.

[0037] Please refer to Figures 1-7 The arrows in the diagram indicate the direction of water flow. This utility model embodiment provides a dual-channel water valve assembly 1, which includes a water valve housing 10, an inlet connector 20 and an outlet connector 30 disposed on the water valve housing 10. The inlet connector 20 forms an inlet channel 201 within the water valve housing 10, and the outlet connector 30 forms an outlet channel 301 within the water valve housing 10. It is understood that the inlet connector 20 is used to connect to an external inlet pipe, and the outlet connector 30 is used to connect to an external outlet pipe.

[0038] The water valve housing 10 also has a first water flow channel 101, a second water flow channel 102 and a third water flow channel 103 formed inside;

[0039] The inlet channel 201 is connected to the first water flow channel 101, and the first water flow channel 101 is connected to the outlet channel 301 through the second water flow channel 102 and the third water flow channel 103; a shut-off valve assembly 104 is also provided on the water valve housing 10, and the shut-off valve assembly 104 is provided on the third water flow channel 103 for controlling the opening / closing of the third water flow channel 103. Understandably, the inlet channel 201, the first water flow channel 101, the second water flow channel 102, and the outlet channel 301 form a normally open channel structure, through which water can flow directly. The inlet channel 201, the first water flow channel 101, the third water flow channel 103, and the outlet channel 301 form a controllable switch channel structure. When the shut-off valve assembly 104 is open, the first water flow channel 101 and the third water flow channel 103 are connected, making the channel structure connected. At this time, both channels can supply water flow, increasing the water flow rate of the water valve assembly 1. When the shut-off valve assembly 104 is closed, only the normally open channel structure formed by the first water flow channel 101 and the second water flow channel 102 is connected, and the water flow rate of the water valve assembly 1 decreases. For example, the second water flow channel 102 can be configured with a smaller inner diameter, which can reduce the flow rate of water flowing through the second water flow channel 102 and increase the heating rate when heated, thus meeting the need for quick hot water. In the case of shutdown and restart, the small water flow channel can also quickly ensure the water temperature rise. When the startup time is sufficient, the entire water flow is heated to the preset temperature, and the shut-off valve assembly 104 can be opened to use a large flow of water, improving the user experience.

[0040] Please refer to Figures 3-7In a preferred embodiment, the first water flow channel 101 forms a first cavity 105 within the water valve housing 10, and a partition channel wall 106 is provided within the first cavity 105. The partition channel wall 106 is used to separate the first water flow channel 101 and the water outlet channel 301.

[0041] The second water flow channel 102 is formed on the partition channel wall 106, and the second water flow channel 102 penetrates the partition channel wall 106 in the thickness direction to connect the first water flow channel 101 and the outlet channel 301. It can be understood that the partition channel wall 106 separates the first water flow channel 101 and the outlet channel 301, and the first water flow channel 101 is connected to the outlet channel 301 through the second water flow channel 102 and the third water flow channel 103. In this embodiment, a second water flow channel 102 penetrating the partition channel wall 106 is formed in the thickness direction of the partition channel wall 106, so that the first water flow channel 101, the second water flow channel 102, and the outlet channel 301 form a normally open channel structure, allowing water to flow from the first water flow channel 101 along the second water flow channel 102 to the outlet channel 301. For example, one or more second water flow channels 102 can be provided, depending on actual usage requirements. The inner diameter of the second water flow channel 102 can be set to a smaller inner diameter, so that the water flow rate of the normally open channel structure is smaller and the temperature can rise rapidly during heating.

[0042] Please refer to Figures 1-3 Furthermore, the water valve assembly 1 also includes a temperature probe 40. The first end of the temperature probe 40 extends into the first cavity 105 to detect the water temperature inside the first cavity 105. The second end of the temperature probe 40 is provided with a signal line 401 to transmit the water temperature signal. Understandably, the temperature probe 40 can detect the water temperature inside the first cavity 105 and transmit the water temperature signal. In devices such as wall-hung boilers, when the water temperature has not reached the preset value, the shut-off valve assembly 104 remains closed, and water flows only from the second water flow channel 102, allowing a small flow of water to quickly heat up. When the water temperature reaches the preset value, it indicates that the entire water flow in the water valve assembly 1 has been heated to the preset value. At this time, the shut-off valve assembly 104 can be opened to connect the first water flow channel 101 and the third water flow channel 103, thereby increasing the water flow rate and further meeting water demand.

[0043] Please refer to Figures 1-7In a preferred embodiment, the water outlet channel 301 is disposed within the partition channel wall 106. One end of the partition channel wall 106 facing outwards is connected to the water outlet connector 30, and the other end of the partition channel wall 106 facing inwards is connected to the shut-off valve assembly 104. The shut-off valve assembly 104 can connect or disconnect the first water flow channel 101 and the water outlet channel 301. It can be understood that the inner tube of the partition channel wall 106 is the water outlet channel 301. The other connection point between the first water flow channel 101 and the water outlet channel 301 is on the inner side of the partition channel wall 106, where the shut-off valve assembly 104 is located. The terms "outer side" and "inner side" refer to their axial direction relative to the partition channel wall 106. The end of the partition channel wall 106 connected to the water outlet connector 30 is the outer side of the partition channel wall 106, while the other end away from the water outlet connector 30 is the inner side. By controlling whether the first water flow channel 101 and the water outlet channel 301 are connected through the shut-off valve assembly 104, the water flow rate of the water valve assembly 1 can be accurately controlled.

[0044] Please refer to Figures 4-7 Furthermore, a movable valve body 1041 is provided on the side of the shut-off valve assembly 104 facing the partition channel wall 106, and the side of the valve body 1041 facing the partition channel wall 106 is the shut-off valve sealing end face 1042.

[0045] When the valve body 1041 moves toward the partition channel wall 106 and the shut-off valve sealing end face 1042 abuts against the partition channel wall 106, the shut-off valve assembly 104 seals the water outlet channel 301. Understandably, when the shut-off valve assembly 104 is closed, the shut-off valve sealing end face 1042 is in close contact with the inner end face of the partition channel wall 106, thereby forming a watertight structure and disconnecting the connection between the first water flow channel 101 and the water outlet channel 301. Through the sealing effect of the shut-off valve sealing end face 1042, a good sealing effect can be achieved, and the structure is simple and occupies a small volume.

[0046] When the valve body 1041 moves away from the partition channel wall 106, a third water flow channel 103 is formed between the first water flow channel 101 and the outlet channel 301. The third water flow channel 103 connects the first water flow channel 101 and the outlet channel 301. Understandably, the third water flow channel 103 is the channel formed between the first water flow channel 101 and the outlet channel 301 when the valve body 1041 moves away from the partition channel; when the shut-off valve assembly 104 is closed, the third water flow channel 103 is not formed.

[0047] Please refer to Figures 4-7In a preferred embodiment, the valve body 1041 is provided with an extension portion 1043 at one end facing the partition channel wall 106, a shut-off valve cavity 1044 is provided inside the valve body 1041, a sealing element 1045 is provided outside the shut-off valve cavity 1044, and a water passage hole 1046 is provided in the extension portion 1043, the water passage hole 1046 connects the water outlet channel 301 and the shut-off valve cavity 1044;

[0048] When the shut-off valve assembly 104 seals the water outlet channel 301, the water flows from the first water flow channel 101 through the second water flow channel 102 to the water outlet channel 301. Part of the water flow in the water outlet channel 301 enters the shut-off valve cavity 1044 through the water passage 1046, so that the water pressure in the shut-off valve cavity 1044 and the water outlet channel 301 are balanced. Understandably, when the shut-off valve assembly 104 is closed, water flows from the first water flow channel 101 and the second water flow channel 102 to the outlet channel 301. The outlet channel 301 is connected to the shut-off valve cavity 1044 through the water passage 1046, and some of the water will enter the shut-off valve cavity 1044. The seal 1045 can prevent water from flowing out of the shut-off valve cavity 1044. At this time, the water pressure balance between the outlet channel 301 and the shut-off valve cavity 1044 is maintained, thereby further maintaining the contact between the shut-off valve sealing end face 1042 and the partition channel wall 106. The shut-off valve sealing end face 1042 will not be blown open by the water pressure in the outlet channel 301, so that the shut-off valve assembly 104 has a better sealing effect.

[0049] Please refer to Figures 1-7 In a further preferred embodiment, the shut-off valve assembly 104 is a solenoid valve, and the water valve housing 10 is provided with an installation cavity 107. The first end of the shut-off valve assembly 104 is disposed in the installation cavity 107, and the shut-off valve assembly 104 is fixedly connected to the water valve housing 10. The second end of the shut-off valve assembly 104 is provided with a shut-off valve connecting line 1047, which is used to connect to an external controller to control the shut-off valve assembly 104 to open / close.

[0050] Please refer to Figures 1-2 , Figure 4 and Figure 6In a preferred embodiment, the water valve assembly 1 further includes a heating water connector 50 and a water supply valve assembly 60. The heating water connector 50 and the water supply valve assembly 60 are disposed on the water valve housing 10. The heating water connector 50 forms a heating water channel 501. The inlet channel 201 is connected to the heating water channel 501 through the water supply valve assembly 60. The water supply valve assembly 60 is used to connect or disconnect the heating water channel 501 and the inlet channel 201. It can be understood that the heating water connector 50 is also a type of outlet connector 30, which is used to connect to the circulating heating water system. When the circulating heating water system needs to be replenished with water, the water supply valve assembly 60 is opened, and the inlet channel 201 is connected to the heating water channel 501. Some of the incoming water flows from the heating water connector 50 to the circulating heating water system. When the water supply valve assembly 60 is closed, the inlet channel 201 is not connected to the heating water connector 50. The heating water connector 50 and the water supply valve assembly 60 are integrated into the water valve assembly 1, which can integrate the water supply needs of the circulating heating water system, further reducing the need for other valves and space occupation.

[0051] Please refer to Figures 1-2 In a preferred embodiment, the water valve assembly 1 further includes a water flow sensor 70, which is mounted on the water valve housing 10. One end of the water flow sensor extends into the water inlet channel 201 or the first water flow channel 101 to detect water flow signals; the other end of the water flow sensor is provided with a water valve connection line 701 to transmit the water flow signals. By setting the water flow sensor 70, water flow or water pressure can be detected in real time, avoiding situations such as dry burning due to blockage and improving safety.

[0052] 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 with a dual-channel structure of any one of the 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.
