Description

Technical Field

[0001] This utility model belongs to the technical field of wall-hung boilers, specifically relating to a multi-channel water outlet valve and a wall-hung boiler. Background Technology

[0002] A wall-hung boiler, also known as a gas-fired wall-mounted heating boiler, is a wall-mounted heating system that uses natural gas or liquefied petroleum gas as its main fuel. It integrates the functions of central heating and domestic hot water supply, making it an ideal heating and hot water solution for modern families.

[0003] Currently, most wall-hung boilers cannot adjust the water flow rate in the bathroom, making it impossible to regulate the rate of water temperature rise. The only way to achieve a temperature increase is by changing the combustion load, which takes a long time. For example, Chinese patent CN220750412U discloses a wall-hung boiler that can rapidly heat up by adding a fire basin, ignition needle, return needle, and heat exchanger. However, this rapid heating method is energy-intensive and inflexible. Furthermore, some products use a water servo structure to regulate the water flow rate in the bathroom. For instance, Chinese patent CN119712901B discloses a servo mixing valve and an integrated water circuit system with a servo mixing valve. This system controls the servo module to maintain the gap between the regulating mechanism and the first water inlet channel, as well as the corresponding cold water flow rate, within a reasonable range. However, its structure makes the water circuit system extremely complex, resulting in a large overall boiler size and high water servo costs.

[0004] Therefore, it is necessary to design a wall-hung boiler that can achieve rapid heating by flexibly adjusting the water flow. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a multi-channel water outlet valve that can flexibly adjust the water flow rate and a wall-hung boiler using the water outlet valve.

Detailed Implementation

[0039] 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.

[0040] 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.

[0041] Please refer to Figures 1-6 This utility model embodiment provides a multi-channel water outlet valve 10, which includes a valve body 101 and a drive motor 102. The drive motor 102 is fixedly connected to the valve body 101. It can be understood that the valve body 101 is provided with a mounting hole for the drive motor 102 to be installed. The output shaft of the drive motor 102 is arranged facing the mounting hole. The first valve core 115 is correspondingly arranged with the mounting hole. The output shaft of the drive motor 102 is fixedly connected to the first valve core 115 through the mounting hole to drive the rotation of the first valve core 115.

[0042] The water valve body 101 has a heating inlet 103, a first heating outlet 104, and a second heating outlet 105. The heating inlet 103 and the first and second heating outlets 104 and 105 are connected to form a first heating channel 106 and a second heating channel 107, respectively. A drive motor 102 is connected to a first valve core 115 and is installed in the first and second heating channels 106 and 107 to control the opening and closing of the first and second heating channels 106 and 107. It is understood that heating circulating water enters the water valve body 101 from the heating inlet 103, passes through the first valve core 115, and is guided by the first valve core 115 to the first heating outlet 104 and / or the second heating outlet 105. In some embodiments, the first heating channel 106 and the second heating outlet 105... The heating channel 107 is configured as a "two-option" system, meaning that when the first heating channel 106 is open, the second heating channel 107 is closed; and when the second heating channel 107 is open, the first heating channel 106 is closed. In some preferred embodiments, the first heating channel 106 and the second heating channel 107 can be opened simultaneously. That is, the first valve core 115 controls the flow distribution of the heating circulating water entering from the heating inlet 103. The water flow is adjusted according to the devices subsequently connected to the first heating channel 106 and the second heating channel 107, thereby achieving flexible adjustment. For example, the first heating channel 106 can be connected to the heating circulation pipeline for whole-house heating, and the second heating channel 107 can be connected to the heat exchanger 30 for heating the water entering the bathroom. This configuration makes the outlet valve 10 compact and feature-rich.

[0043] The water valve body 101 also has a bathroom inlet 108 and a bathroom outlet 109. The bathroom inlet 108 and the bathroom outlet 109 are connected to form a first bathroom passage 110. A shut-off valve assembly 111 is installed on the first bathroom passage 110, which can control the opening and closing of the first bathroom passage 110. It can be understood that the shut-off valve assembly 111 is located between the bathroom inlet 108 and the bathroom outlet 109, and it is used to regulate the flow rate of the bathroom water and the opening or closing of the first bathroom passage 110. For example, the shut-off valve assembly 111 can be a solenoid valve, thus enabling accurate control of the water flow rate.

[0044] Please refer to Figures 1-6In this embodiment, the water valve body 101 is further provided with a second bathroom channel 112, which connects the bathroom inlet 108 and the first bathroom channel 110. A shut-off valve assembly 111 is disposed between the second bathroom channel 112 and the first bathroom channel 110, and is used to control the connection or disconnection of the first bathroom channel 110 and the second bathroom channel 112. It is understood that the first bathroom channel 110 is located near the bathroom outlet 109, and the second bathroom channel 112 is located near the bathroom inlet 108. The shut-off valve assembly 111 is disposed between these two channels, thus controlling whether the first bathroom channel 110 and the second bathroom channel 112 are connected. In other embodiments, the shut-off valve assembly 111 can also control the inner diameter of the connection between the first bathroom channel 110 and the second bathroom channel 112, thus accurately controlling the bathroom water flow rate.

[0045] Please refer to Figures 1-6 In this embodiment, the shut-off valve assembly 111 has a movable sealing surface 113 on the side facing the second bathroom channel 112. The shut-off valve assembly 111 can control the movable sealing surface 113 to move toward / away from the second bathroom channel 112. When the movable sealing surface 113 moves toward the second bathroom channel 112 and abuts against the end face of the second bathroom channel 112, the second bathroom channel 112 is disconnected from the first bathroom channel 110. When the movable sealing surface 113 moves away from the second bathroom channel 112, the second bathroom channel 112 is connected to the first bathroom channel 110.

[0046] Please refer to Figures 1-6In this embodiment, the water valve body 101 is also provided with a third bathroom channel 114, which connects the bathroom inlet 108 and the first bathroom channel 110. The inner diameter of the third bathroom channel 114 is smaller than the inner diameter of the second bathroom channel 112. It can be understood that the third bathroom channel 114 is directly connected to the first bathroom channel 110 and does not pass through the shut-off valve assembly 111. That is, the first bathroom channel 110 and the third bathroom channel 114 are normally open channels. Bathroom water from the bathroom inlet 108 can flow directly from the third bathroom channel 114 to the first bathroom channel 110 and then out of the bathroom outlet 109. In this embodiment, the inner diameter of the third bathroom channel 114 is smaller than that of the second bathroom channel 112, meaning that the third bathroom channel 114 provides a small flow of bathroom water. When the user needs hot water immediately after the boiler starts up, the second bathroom channel 112 can be closed, and only the third bathroom channel 114 can be used. At this time, the water flow is small, and the boiler can fully heat the bathroom water in the pipes. Once the target temperature is reached, the second bathroom channel 112 is opened again. At this time, the second bathroom channel 112 and the third bathroom channel 114 are connected simultaneously, achieving a large flow of hot water supply. During bathroom use... When the unit is restarted after a shutdown, the secondary heating process can still begin with the third bathroom channel 114 supplying hot water. Once the water temperature reaches the target value, the second bathroom channel 112 can be opened simultaneously. Alternatively, if the user's bathroom water pressure is too high, opening the second bathroom channel 112 would result in excessive water flow, causing the water to flow out before it is fully heated, preventing the water temperature from reaching the target value. In this case, only the third bathroom channel 114 can be used while the second bathroom channel 112 is closed to slow the water flow and ensure the water is fully heated before flowing out. The coordination of the second bathroom channel 112 and the third bathroom channel 114 allows for flexible control of the bathroom water supply, adapting to different usage conditions.

[0047] Please refer to Figures 1-6 In a preferred embodiment, a second valve core 116 is provided within the second bathroom channel 112, and a third bathroom channel 114 is formed on the side of the second valve core 116 to connect the bathroom inlet 108 and the bathroom outlet 109. It can be understood that the third bathroom channel 114 is a side channel of the second bathroom channel 112, formed by opening a connecting hole in the second valve core 116. The third bathroom channel 114 can connect to the first bathroom channel 110 without passing through the shut-off valve assembly 111. In this embodiment, the third bathroom channel 114 is offset from the shut-off valve assembly 111, allowing the water flow from the third bathroom channel 114 to directly impact the shut-off valve assembly 111, causing it to fail and ensuring the service life of the outlet valve 10.

[0048] Please refer to Figures 1-6 In this embodiment, the multi-channel water outlet valve 10 includes a heating operation state and a bathroom operation state:

[0049] Heating operation status: The drive motor 102 controls the first valve core 115 to rotate, connecting the first heating channel 106 and closing the second heating channel 107. The shut-off valve assembly 111 controls the first bathroom channel 110 to disconnect from the second bathroom channel 112.

[0050] Bathroom working status: The drive motor 102 controls the first valve core 115 to rotate, connecting the second heating channel 107 and closing the first heating channel 106. The shut-off valve assembly 111 controls the first bathroom channel 110 to connect with the second bathroom channel 112. The first bathroom channel 110 and the third bathroom channel 114 are normally connected.

[0051] Please refer to Figures 1-6 In this embodiment, the bathroom inlet 108 is located on one side of the water valve body 101, and the shut-off valve assembly 111 is located on the opposite side of the bathroom inlet 108. The shut-off valve assembly 111 is partially inserted into the first bathroom channel 110 and faces the bathroom inlet 108. The bathroom outlet 109 is located on the side adjacent to the shut-off valve assembly 111. When the shut-off valve assembly 111 is open, it connects the bathroom inlet 108 and the bathroom outlet 109 to connect the first bathroom channel 110. When the shut-off valve assembly 111 is closed, it disconnects the first bathroom channel 110. It can be understood that the shut-off valve assembly 111 and the bathroom inlet 108 are respectively located on opposite sides of the outlet valve 10, and the shut-off valve assembly 111 can be inserted into the water valve body 101 and extend to one side of the bathroom inlet 108.

[0052] Please refer to Figures 1-6 In this embodiment, the heating inlet 103 is located on one side of the water valve body 101, and the first heating outlet 104 is located on the opposite side of the heating inlet 103. The drive motor 102 is perpendicular to the heating inlet 103 or the first heating outlet 104, and the second heating outlet 105 is adjacent to the drive motor 102. The first valve core 115 is located adjacent to the heating inlet 103. The first valve core 115 can control the heating inlet 103 to connect with the first heating outlet 104 to form a first heating channel 106, or control the heating inlet 103 to connect with the second heating outlet 105 to form a second heating channel 107.

[0053] Please refer to Figures 1-7This utility model embodiment also provides a wall-hung boiler, which includes a burner 20, a heat exchanger 30, a heating circulating water pipe 40, a bathroom water pipe 50, and a multi-channel outlet valve 10 as described above; the heating circulating water pipe 40 passes through the burner 20 and extends to the outlet valve 10 and connects to the heating inlet 103, the first heating outlet 104 is connected to the heating circulating water pipe 40 on the other side, and the second heating outlet 105 is connected to the heat exchanger 30; the bathroom water pipe 50 includes a bathroom water inlet pipe and a bathroom water outlet pipe, the bathroom water inlet pipe is connected to the heat exchanger 30 and then connected to the bathroom inlet 108, and the bathroom water outlet pipe is connected to the bathroom outlet 109, so that the bathroom inlet water and the heating water of the second heating outlet 105 exchange heat in the heat exchanger 30. Understandably, the wall-hung boiler includes heating circulating water and bathroom water. The heating circulating water flows through the house via heating circulating water pipe 40 to provide heating. Heating circulating water pipe 40 passes through burner 20, where it heats the heating circulating water in the pipe. The heated heating circulating water then enters outlet valve 10, which controls the direction and flow distribution of the heated heating circulating water. Most of it is used for indoor heating, while a small portion flows to heat exchanger 30 to heat bathroom water. One end of bathroom water pipe 50 is connected to a tap water pipe or a filter water pipe. At this point, cold water enters bathroom water pipe 50. The cold bathroom water first passes through heat exchanger 30, where it exchanges heat with the heating water, raising its temperature before flowing to outlet valve 10, which controls the outflow of bathroom water. In this way, heating water and bathroom water can be controlled through a single outlet valve 10, and the flow direction and flow rate of bathroom water and heating water can be flexibly controlled to adjust according to different needs.

[0054] In this embodiment, the wall-hung boiler also includes a main controller 60, which is electrically connected to the drive motor 102 and the shut-off valve assembly 111 to control the operating conditions of the drive motor 102 and the shut-off valve assembly 111.
