[0051] Figure 2 The schematic diagram of the water circuit structure of the wall-mounted boiler water circuit system provided in this embodiment is shown. Figure 3 The schematic diagram of the structure of the water outlet valve 100 provided in this embodiment from one perspective is shown. Figure 4 The schematic diagram of the structure of the wall-mounted boiler water circuit system provided in this embodiment is shown. As Figures 2 - 4 shown, this embodiment provides a wall-mounted boiler water circuit system, which includes a combustion chamber 200 and a water outlet valve 100. The combustion chamber 200 can heat the water therein; the water outlet valve 100 includes a valve body 1, and the valve body 1 is provided with a hot water inlet 1111, and the hot water inlet 1111 faces the hot water outlet 201 of the combustion chamber 200, and the hot water inlet 1111 and the hot water outlet 201 are directly communicated through a connecting pipeline 600. The connecting pipeline 600 can be directly pulled down to the hot water inlet 1111 after being led out from the hot water outlet 201. The water outlet valve 100 can selectively supply water to the heating system 500 or the bathroom system to provide domestic water for users or meet the heating needs of users. Compared with Figure 1 the wall-mounted boiler water circuit system in the prior art shown, in the wall-mounted boiler water circuit system provided in this embodiment, by setting the hot water inlet 1111 of the valve body 1 to face the hot water outlet 201 of the combustion chamber 200 and directly connecting the two, the distance between the hot water inlet 1111 and the hot water outlet 201 can be shortened, thereby reducing the length and material consumption of the connecting pipeline 600, and further reducing the material cost to a certain extent; in addition, by adopting the above setting method, the connecting pipeline 600 can be processed into a straight pipe structure, and the hot water inlet 1111 and the hot water outlet 201 can be connected without too many bending parts, thereby avoiding the phenomenon of large water resistance caused by too many bending parts on the connecting pipeline 600.

[0052] It should be explained that the heating system 500 specifically refers to terminal heat dissipation components such as radiators, floor heating pipes or fan coil units. The water heated in the combustion chamber 200 can be pumped to the above-mentioned terminal heat dissipation components through the water outlet valve 100, and the heat is dissipated into the indoor air by heat dissipation, thereby increasing the indoor environmental temperature to meet the heating needs of users. The bathroom system specifically refers to the water using devices for users to take showers, wash their faces, etc. Therefore, both the heating system 500 and the bathroom system are relatively mature technologies in the art, and the specific structures of the heating system 500 and the bathroom system will not be elaborated in this embodiment.

[0053] This embodiment does not limit the material of the connecting pipeline 600, and it can be made of copper pipe, corrugated pipe, stainless steel pipe, plastic pipe, etc.

[0054] As Figure 2 and Figure 3As shown in the figure, the water circuit system of the wall-mounted boiler further includes a heat exchange structure 300 and a water inlet valve 400. The heat exchange structure 300 includes a heat exchange channel 310 and a water supply channel 320 that are heat exchange - matched. The water inlet valve 400 can supply water to the combustion chamber 200 and the water supply channel 320. The valve body 1 is also provided with a heating channel 121, a bathroom channel 142, a first heat exchange water inlet flow channel 131, and a first heat exchange water outlet flow channel 141. The hot water inlet 1111 can selectively communicate with the heating channel 121 or the first heat exchange water inlet flow channel 131. The outlet of the first heat exchange water inlet flow channel 131 is connected to the inlet of the heat exchange channel 310. The outlet of the heat exchange channel 310 is connected to the second heat exchange water outlet flow channel 402 of the water inlet valve 400, so as to introduce the water that has completed heat exchange with the water supply channel 320 in the heat exchange channel 310 into the combustion chamber 200 through the water inlet valve 400. The inlet of the first heat exchange water outlet flow channel 141 is connected to the outlet of the water supply channel 320. The second heat exchange water inlet flow channel 401 of the water inlet valve 400 is connected to the inlet of the water supply channel 320, so as to introduce the water in the external water source into the water supply channel 320. The outlet of the first heat exchange water outlet flow channel 141 is connected to the bathroom channel 142.

[0055] That is to say, when the hot water inlet 1111 is communicated with the heating channel 121, the hot water heated by the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipeline 600, the hot water inlet 1111, and the heating channel 121 in sequence, and then flow to the heating system 500 to provide heating requirements for users. The water that has exchanged heat with the outside in the heating system 500 can flow back to the combustion chamber 200 through the water inlet valve 400 to be reheated, thus forming a heating water circulation loop. When the hot water inlet 1111 is communicated with the first heat exchange water inlet flow channel 131, the hot water heated by the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipeline 600, the hot water inlet 1111, and the first heat exchange water inlet flow channel 131 in sequence, and then flow into the heat exchange channel 310 of the heat exchange structure 300. After exchanging heat with the water in the water supply channel 320, it flows into the combustion chamber 200 through the water inlet valve 400 to be reheated, thus forming a heat exchange circulation loop. The water in the external water source can flow into the water supply channel 320 of the heat exchange structure 300 through the water inlet valve 400. After exchanging heat with the water in the heat exchange channel 310, it then flows through the first heat exchange water outlet flow channel 141 and the bathroom channel 142 in sequence and flows into the bathroom system to provide domestic water for users.

[0056] It should be noted that both the combustion chamber 200 and the water inlet valve 400 are relatively mature technologies in the field, and the specific structures of the combustion chamber 200 and the water inlet valve 400 will not be elaborated in this embodiment.

[0057] It should be noted that, as Figure 2As shown, in this embodiment, the heat exchange structure 300 has a cross-flow channel structure, that is, the water flows in the heat exchange channel 310 and the water supply channel 320 form a cross trend. The heat exchange structure 300 is a relatively mature technology in this field, and the specific structure of the heat exchange structure 300 will not be elaborated in this embodiment.

[0058] It should be noted that, for the convenience of description, as Figure 3 shown, the height direction of the water outlet valve 100 after actual installation is defined as the up-down direction. Among them, the side of the water outlet valve 100 close to the combustion chamber 200 is defined as up, the side of the water outlet valve 100 away from the combustion chamber 200 is defined as down, the side of the water outlet valve 100 close to the heat exchange structure 300 is defined as back, and the side of the water outlet valve 100 away from the heat exchange structure 300 is defined as front; when the user stands facing the front of the water outlet valve 100, the side of the water outlet valve 100 facing the user's right hand is defined as right, and the side of the water outlet valve 100 facing the user's left hand is defined as left. In addition, hereinafter, the height direction of the valve body 1 refers to the up-down direction, the width direction of the valve body 1 refers to the left-right direction, and the thickness direction of the valve body 1 refers to the front-back direction.

[0059] Figure 5 The structural schematic diagram of the water outlet valve 100 provided in this embodiment is shown from another perspective. Figure 6 Shown is Figure 5 the sectional structural schematic diagram at A-A. As Figures 5 - 6 and combined with Figure 2 、 Figure 3 shown, the valve body 1 includes a three-way valve part 11 and an extension valve part 12. A main valve cavity 1101 and a first cavity 1102 and a second cavity 1103 located on both sides of the main valve cavity 1101 are formed in the three-way valve part 11. The first cavity 1102 is communicated with the heating channel 121, the second cavity 1103 is communicated with the first heat exchange water inlet channel 131, the hot water inlet 1111 is opened on the three-way valve part 11 and is communicated with the main valve cavity 1101, the extension valve part 12 is formed on the side of the three-way valve part 11 away from the hot water inlet 1111, and the heating channel 121 is opened in the extension valve part 12; the water outlet valve 100 further includes a switching mechanism 3, and the switching mechanism 3 is movably arranged in the three-way valve part 11 to selectively open the passage between the main valve cavity 1101 and the first cavity 1102 or the passage between the main valve cavity 1101 and the second cavity 1103. When the switching mechanism 3 opens the passage between the main valve cavity 1101 and the first cavity 1102, the hot water in the combustion chamber 200 can circulate in the heating water circulation loop; when the switching mechanism 3 opens the passage between the main valve cavity 1101 and the second cavity 1103, the hot water in the combustion chamber 200 can circulate in the heat exchange water circulation loop, that is, the switching mechanism 3 realizes the switching between the heating water circulation loop and the heat exchange water circulation loop to selectively provide domestic water for the user or meet the heating needs of the user.

[0060] Figure 7 The structural schematic diagram of the switching mechanism 3 and the partition component 112 provided in this embodiment is shown. Figure 8 The sectional structural schematic diagram of the switching mechanism 3 and the partition component 112 provided in this embodiment is shown. As Figures 7 - 8 and in combination with Figure 6 shown, the three-way valve part 11 includes a body 111 and a partition component 112 arranged in the valve cavity of the body 111. The partition component 112 includes a first partition sleeve 1121 and a second partition sleeve 1122. The first partition sleeve 1121 and the second partition sleeve 1122 are arranged at intervals along the axial direction of the valve cavity of the body 111 and are both in sealing cooperation with the cavity wall of the valve cavity of the body 111, thereby dividing the valve cavity of the body 111 into a main valve cavity 1101, a first cavity 1102, and a second cavity 1103. The first partition sleeve 1121 is located between the main valve cavity 1101 and the first cavity 1102, and the second partition sleeve 1122 is located between the main valve cavity 1101 and the second cavity 1103. The switching mechanism 3 includes a valve stem 31, a first seal seat 32, and a second seal seat 33. The first seal seat 32 and the second seal seat 33 are arranged at intervals along the axial direction of the valve stem 31 and are both connected to the valve stem 31. The valve stem 31 can move along the axial direction of the three-way valve part 11, thereby driving the first seal seat 32 and the second seal seat 33 to move, so as to selectively block the first partition sleeve 1121 with the first seal seat 32 or block the second partition sleeve 1122 with the second seal seat 33. When the first seal seat 32 blocks the first partition sleeve 1121, the second seal seat 33 is arranged at an interval from the second partition sleeve 1122. At this time, the main valve cavity 1101 is communicated with the second cavity 1103; when the second seal seat 33 blocks the second partition sleeve 1122 and the first seal seat 32 is arranged at an interval from the first partition sleeve 1121, at this time, the main valve cavity 1101 is communicated with the first cavity 1102, thereby realizing three-way switching.

[0061] Optionally, the water outlet valve 100 further includes a driving mechanism 2. The output end of the driving mechanism 2 is connected to the valve stem 31 to drive the valve stem 31 to move along the axial direction of the three-way valve part 11. In this embodiment, the driving mechanism 2 is a synchronous motor. Of course, in other embodiments, according to different designs of the switching mechanism 3, the driving mechanism 2 can also be a stepping motor or other driving devices.

[0062] As Figures 3 - 6 shown, the valve body 1 further includes a second valve part 13 and a first valve part 14. The second valve part 13 is formed on one side of the three-way valve part 11, and the first valve part 14 is formed on one side of the extension valve part 12. Moreover, the second valve part 13 and the first valve part 14 are arranged at intervals along the axial direction of the extension valve part 12 and are connected. The first heat exchange water inlet flow channel 131 is opened in the second valve part 13, and the sanitary ware channel 142 and the first heat exchange water outlet flow channel 141 are both opened in the first valve part 14.

[0063] It should be noted that, in this embodiment, the hot water inlet 1111 is coaxially arranged with the heating channel 121, and the first chamber 1102 and the second chamber 1103 are respectively located on both sides of the axis of the hot water inlet 1111. During actual installation, the axis directions of the hot water inlet 1111 and the heating channel 121 extend in the up-down direction, with the hot water inlet 1111 facing upward and the outlet of the heating channel 121 facing downward. The axis direction of the three-way valve portion 11 extends in the front-back direction, and the driving mechanism 2 is located in front of the valve body 1. Both the second valve portion 13 and the first valve portion 14 are located on the right side of the three-way valve portion 11. The hot water inlet 1111, the heating channel 121, the first heat exchange water inlet flow channel 131, and the sanitary ware channel 142 are roughly arranged in a square layout, making full use of the space of the valve body 1 in the width direction and the thickness direction, greatly reducing the installation height of the entire water circuit system of the wall-mounted boiler, and optimizing the space layout of the entire system. In addition, by adopting the above setting method, the relatively large driving mechanism 2 can be arranged on the side of the valve body 1 (in the prior art, the driving mechanism is usually arranged between the valve body and the combustion chamber, so a relatively large space needs to be reserved between the valve body and the combustion chamber for installing the driving mechanism), so as to avoid the interval area between the valve body 1 and the combustion chamber 200, make full use of the space of the valve body 1 in the thickness direction, further shorten the distance between the valve body 1 and the combustion chamber 200, and thus reduce the length of the connecting pipeline 600.

[0064] Optionally, the first chamber 1102 is connected to the heating channel 121 through a heating communication flow channel 1001, and the axis of the heating communication flow channel 1001 is inclined relative to the axis of the three-way valve portion 11. In the prior art, the first chamber 1102 is coaxially arranged with the heating channel 121 and extends in the up-down direction. When the switching mechanism 3 opens the passage between the main valve chamber 1101 and the first chamber 1102, the first sealing seat 32 is equivalent to blocking the passage between the first chamber 1102 and the heating channel 121, and the water in the main valve chamber 1101 will flow between the first sealing seat 32 and the chamber wall of the first chamber 1102, thus generating a relatively large water resistance; while in this embodiment, by setting the inclined heating communication flow channel 1001, an opening can be exactly formed at the interval in the downward direction along the axis of the three-way valve portion 11 between the first sealing seat 32 and the first partition sleeve 1121, and the water in the main valve chamber 1101 can flow out from this opening under the action of its own gravity, thereby reducing the water resistance, increasing the water flow rate to a certain extent, and also playing a role in reducing the head damage of the circulating water pump, prolonging the service life of the circulating water pump, and reducing the user's usage cost.

[0065] Figure 9 The sectional view schematic diagram of the water outlet valve 100 provided in this embodiment is shown from another perspective. As Figure 9 and in combination with Figure 3 、 Figure 5As shown, the second chamber 1103 is connected to the first heat exchange water inlet flow channel 131 through a heat exchange connection flow channel 1002, and the axis of the heat exchange connection flow channel 1002 is inclined relative to the axis of the three-way valve portion 11. Compared with the straight channels in the prior art, in this embodiment, by providing the inclined heat exchange connection flow channel 1002, it is equivalent to increasing the cross-sectional area of the inlet of the heat exchange connection flow channel 1002, thereby reducing the water resistance of the water flowing from the second chamber 1103 to the first heat exchange water inlet flow channel 131; in addition, the inclined heat exchange connection flow channel 1002 is also convenient for processing, reduces the use of sealing plugs, and at the same time can also reduce potential risk points of leakage.

[0066] Figure 10 The structural schematic diagram of the water outlet valve 100 provided by this embodiment is shown from another perspective. As Figure 10 and in combination with Figure 6 shown, a bypass flow channel 151 is further provided on the valve body 1, and the bypass flow channel 151 can selectively connect the heating channel 121 and the second chamber 1103. When the main valve chamber 1101 is connected to the first chamber 1102, when the heat exchange structure 300 dries out due to lack of water, the water in the heating channel 121 can flow through the bypass flow channel 151 and successively through the second chamber 1103, the heat exchange connection flow channel 1002, and the first heat exchange water inlet flow channel 131 into the heat exchange channel 310 to avoid damage to the heat exchange structure 300 due to dry burning caused by lack of water.

[0067] Specifically, the valve body 1 further includes a bypass valve portion 15, the bypass valve portion 15 is formed on the extension valve portion 12, the bypass flow channel 151 is opened in the bypass valve portion 15, and a check valve 1511 is provided in the bypass flow channel 151 to only allow the water in the heating channel 121 to flow into the second chamber 1103 to prevent the water in the second chamber 1103 from flowing back. Optionally, a bypass port 152 communicating with the bypass flow channel 151 is opened on the bypass valve portion 15, and a bypass plug 153 is detachably plugged at the bypass port 152. One end of the check valve 1511 abuts against the inner side of the bypass plug 153. When maintenance is required, the operator only needs to open the bypass plug 153, which is convenient and fast.

[0068] In this embodiment, the bypass valve portion 15 is formed on the front side of the extension valve portion 12, that is, the bypass valve portion 15 is located below the driving mechanism 2. The operator can perform maintenance on it from the front of the valve body 1, further improving the convenience of the operator's operation; and this design makes the bypass valve portion 15 located between the three-way valve portion 11 and the extension valve portion 12, making the structure of the entire water outlet valve 100 more compact, the bypass connection distance shorter, and thus the response time can be shortened.

[0069] Of course, in other embodiments, a bypass valve portion 15 may also be provided on a side of the extension valve portion 12 away from the second valve portion 13, that is, the bypass valve portion 15 is located on the left side of the extension valve portion 12, and the above effects can also be achieved.

[0070] As Figure 9 and Figure 10 shown, a connection interface 132 communicating with the first heat exchange water inlet flow channel 131 is further provided on the second valve portion 13. A sensing component 4 can be connected at the connection interface 132 to enable a user to detect parameters such as the temperature and pressure of the water in the first heat exchange water inlet flow channel 131. Optionally, the sensing component 4 can be but is not limited to a pressure switch, a pressure sensor, a pressure gauge, a temperature sensor, etc.

[0071] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
