Description

Technical Field

[0001] This utility model belongs to the technical field of heating and hot water boiler equipment, specifically relating to a miniaturized water outlet valve body and a wall-mounted boiler. Background Technology

[0002] Existing gas-fired wall-hung boilers are mainly divided into European-style and Japanese-style boilers according to their structure. European-style boilers, introduced to my country from Europe as a heating and hot water system, feature a split outer shell, a double-sealed combustion chamber, and water and gas circuit components mounted on the base plate in a semi-open installation. The expansion tank is typically mounted on the back panel. This complex structure results in a relatively large size. Japanese-style boilers, introduced from Japan, are essentially a forced-draft gas water heater structure, with added heating components (heating water circuit, expansion tank, etc.) to form the boiler structure. Their size is slightly smaller than European-style boilers, but still relatively large. Both European and Japanese-style boilers use a direct-connection installation structure between the outlet valve and the drive motor, meaning the drive motor and outlet are aligned in a straight line. This results in a longer overall length and larger size for the outlet valve assembly. Figure 1 As shown, this is not conducive to the miniaturization design of wall-hung boilers.

[0003] Therefore, it is necessary to design a miniaturized water outlet valve body and wall-mounted boiler. 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] Please refer to Figures 2-9 This utility model embodiment provides a miniaturized water outlet valve body 7, including a water outlet valve body 10, a three-way valve assembly 20 and a motor assembly 30;

[0039] The main body 10 of the water outlet valve is provided with an inlet connector 101 and an outlet connector 102. The inlet connector 101 and the outlet connector 102 are connected inside the main body 10 of the water outlet valve to form a water flow channel.

[0040] The main body 10 of the outlet valve is provided with a first valve group connection hole 103, which is connected to the water flow channel. The three-way valve assembly 20 is detachably connected to the first valve group connection hole 103 to control the opening or closing of the water flow channel. It can be understood that one end of the three-way valve assembly 20 is inserted into the water flow channel and corresponds to the size of the water flow channel, so that the three-way valve assembly 20 can control the opening or closing of the water flow channel, that is, control whether the inlet connector 101 and the outlet connector 102 are connected.

[0041] The motor assembly 30 is detachably connected to the three-way valve assembly 20 and is used to control the operating conditions of the three-way valve assembly 20. The output shaft 302 of the motor assembly 30 is perpendicular to the axial direction of the water outlet connector 102. It can be understood that the motor assembly 30 is the drive source for changing the operating conditions of the three-way valve assembly 20. As described below, the three-way valve assembly 20 contains a three-way valve core 202. By controlling the rotation of the three-way valve core 202, the motor assembly 30 can control the connection or disconnection of the water flow channel. The output shaft 302 of the motor assembly 30 is connected to the three-way valve core 202. The direction of the output shaft 302 is the axial direction of the output shaft 302. The axial direction of the water outlet connector 102 refers to the fact that the water outlet connector 102 is a section of pipe, and the axial direction of this pipe section is the axial direction of the water outlet connector 102. The two are set perpendicularly, that is, the motor assembly 30 adopts an upper mounting structure to connect with the three-way valve assembly 20. The motor assembly 30 is set on the side of the water outlet valve body 7, not at the end opposite to the water outlet connector 102. This can greatly shorten the overall length of the water outlet valve body 7, so that the water outlet valve body 7 can be miniaturized and the structure is more reasonable.

[0042] Please refer to Figures 2-5 In this embodiment, the three-way valve assembly 20 includes a three-way valve housing 201, a three-way valve core 202, and a first fixing spring 203. The three-way valve core 202 is disposed inside the three-way valve housing 201 or disposed in the lower part of the three-way valve housing 201. A first connecting part 204 is disposed in the upper part of the three-way valve housing 201. The motor assembly 30 is detachably connected to the first connecting part 204.

[0043] The output shaft 302 of the motor assembly 30 is inserted into the first connecting part 204 and connected to the three-way valve core 202. The first connecting part 204 has a through first connecting hole 205, and the lower part of the motor assembly 30 has a first groove 301. When the motor assembly 30 is connected to the three-way valve assembly 20, the first connecting hole 205 corresponds to the first groove 301. The first fixing spring 203 passes through the first connecting hole 205 and the first groove 301 to fix the motor assembly 30 and the three-way valve assembly 20. It can be understood that the motor assembly 30 can be a stepper motor, whose output shaft 302 is connected to the three-way valve core 202. When the output shaft 302 rotates, it can drive the three-way valve core 202 to rotate. The end of the three-way valve core 202 is set in the water flow channel and corresponds to the shape of the water flow channel, so as to realize the connection or disconnection of the water flow channel. Two first connecting holes 205 can be provided oppositely. When the two ends of the first fixing spring 203 pass through the first connecting hole 205, they engage with the first groove 301, generating a clamping force on the first groove 301 to fix the motor assembly 30 and the three-way valve assembly 20. To disassemble, it is only necessary to pry open the first fixing spring 203. The motor assembly 30 is detachably connected to the three-way valve assembly 20 via the first fixing spring 203, which facilitates the assembly of the outlet valve body 7 and subsequent maintenance.

[0044] Please refer to Figures 2-5 In this embodiment, the three-way valve assembly 20 further includes a second retaining spring 206. A through second connecting hole 104 is provided on the first valve group connecting hole 103, and a second groove 207 is provided on the three-way valve housing 201. When the three-way valve assembly 20 is connected to the first valve group connecting hole 103, the second connecting hole 104 corresponds to the second groove 207. The second retaining spring 206 passes through the second connecting hole 104 and the second groove 207 to fix the three-way valve assembly 20 to the outlet valve body 10. It is understood that two second connecting holes 104 can also be provided. Both ends of the second retaining spring 206 pass through the second connecting hole 104 and are engaged at the second groove 207, generating a clamping force on the three-way valve assembly 20 to fix the three-way valve assembly 20 and the first valve group connecting hole 103. To disassemble, only the second retaining spring 206 needs to be pried open. The three-way valve assembly 20 is detachably connected to the first valve group connection hole 103, that is, the three-way valve assembly 20 is detachably connected to the outlet valve body 10, which facilitates the assembly and maintenance of the outlet valve body 7.

[0045] Please refer to Figures 2-4 , Figures 8-9In this embodiment, the water outlet connector 102 includes a first water outlet connector 105 and a second water outlet connector 106. The first water outlet connector 105 and the second water outlet connector 106 are respectively connected to the three-way valve assembly 20. When the motor assembly 30 controls the movement of the three-way valve assembly 20, it can control the water inlet connector 101 to be connected to the first water outlet connector 105 and the second water outlet connector 106; or, the water inlet connector 101 is connected to the first water outlet connector 105 and disconnected from the second water outlet connector 106; or, the water inlet connector 101 is disconnected from the first water outlet connector 105 and connected to the second water outlet connector 106. It can be understood that the first water outlet connector 105 and the second water outlet connector 106 are respectively connected to the three-way valve assembly 20 to form a first water outlet channel and a second water outlet channel, which are independent. The water flow channel of the water inlet connector 101 is split at the three-way valve assembly 20 to the first water outlet channel and the second water outlet channel, and the three-way valve assembly 20 controls the direction of water flow. For example, the three-way valve assembly 20 can be a T-type three-way valve, which allows the inlet connector 101 to be simultaneously connected to both outlet connectors 102, or connected to either outlet connector 102 and disconnected from the other outlet connector 102. The first outlet connector 105 and the second outlet connector 106 can correspond to the bathroom outlet connector 102 and the heating outlet connector 102, respectively. When the heating water is circulating, the water flow channel to the heating water connector can be closed, supplying water only to the bathroom outlet connector 102, thus providing flexible water supply.

[0046] Please refer to Figures 2-4 , Figure 6 In this embodiment, the main body 10 of the water outlet valve is provided with a first water outlet 107, which is connected to the water flow channel. The first water outlet 107 is provided with a third connecting hole 108. The first water outlet connector 105 includes a first inner connection end 109 and a first outer connection end 110. The first inner connection end 109 is inserted into the first water outlet 107 to connect the first water outlet connector 105 and the first water outlet 107.

[0047] The main body 10 of the water outlet valve also includes a third retaining spring 111. A third groove 112 is provided on the first inner end 109. When the first water outlet connector 105 is connected to the first water outlet 107, the third connecting hole 108 corresponds to the third groove 112. The third retaining spring 111 passes through the third connecting hole 108 and the third groove 112 to fix the first water outlet connector 105 and the first water outlet 107. It can be understood that there can be two third connecting holes 108. When the two ends of the third retaining spring 111 pass through the third connecting hole 108, they are engaged with the third groove 112, generating a clamping force on the third groove 112 to fix the first water outlet connector 105 and the first water outlet 107. To remove them, it is only necessary to pry open the third retaining spring 111. The first water outlet connector 105 is detachably connected to the first water outlet 107 through the third retaining spring 111, which facilitates the assembly and subsequent maintenance of the water outlet valve body 7.

[0048] Please refer to Figures 2-4 In this embodiment, the axial direction of the first outlet 107 is perpendicular to the axial direction of the first valve group connection hole 103. A second valve group connection hole 113 is provided between the first outlet 107 and the first valve group connection hole 103, and the second valve group connection hole 113 communicates with the water flow channel. The outlet valve body 7 also includes a bypass valve assembly 114, which is disposed in the second valve group connection hole 113 and fixedly connected to the outlet valve body 10. It can be understood that the bypass valve is used to prevent the wall-mounted boiler 1 from overheating and being damaged when the circuit flow is abnormal (such as blockage or closure). The bypass valve assembly 114 is provided with at least one sealing ring. When the bypass valve is connected to the second valve group connection hole 113, the sealing ring is press-fitted with the inner wall of the second valve group connection hole 113; or the bypass valve assembly 114 is provided with threads, and the inner wall of the second valve group connection hole 113 is provided with corresponding threads, and the two are threadedly connected. The bypass valve also ensures that a small circulation can be formed inside the boiler 1 in case of an abnormality, preventing the hot water from being overheated inside the boiler 1 and improving safety performance.

[0049] Please refer to Figures 2-4 In this embodiment, the main body 10 of the water outlet valve is provided with a second water outlet 115, which is connected to the water flow channel. The second water outlet 115 is provided with a fourth connecting hole 116. The second water outlet connector 106 includes a second inner connection end 117 and a second outer connection end 118. The second inner connection end 117 is inserted into the second water outlet 115 to connect the second water outlet connector 106 and the second water outlet 115.

[0050] The main body 10 of the water outlet valve also includes a fourth retaining spring 119. A fourth groove 120 is provided on the second inner end 117. When the second water outlet connector 106 is connected to the second water outlet 115, the fourth connecting hole 116 corresponds to the fourth groove 120. The fourth retaining spring 119 passes through the fourth connecting hole 116 and the fourth groove 120 to fix the second water outlet connector 106 and the second water outlet 115. It is understood that there can be two relatively opposite fourth connecting holes 116. When the two ends of the fourth retaining spring 119 pass through the fourth connecting hole 116, they engage with the fourth groove 120, generating a clamping force on the fourth groove 120 to fix the second water outlet connector 106 and the second water outlet 115. To remove them, only the fourth retaining spring 119 needs to be pried open. The second water outlet connector 106 is detachably connected to the second water outlet 115 via the fourth retaining spring 119, facilitating the assembly and subsequent maintenance of the water outlet valve body 7.

[0051] Please refer to Figures 2-4 , Figure 6 In this embodiment, the outlet valve body 10 is also provided with a probe interface 121, which is connected to the water flow channel. The outlet valve body 7 also includes a probe assembly 122, which includes a temperature sensor and / or a pressure sensor. The probe assembly 122 is fixedly connected to the probe interface 121, and one end of the probe assembly 122 extends into the water flow channel to measure the parameters of the water flow inside the outlet valve body 7. It can be understood that by detecting parameters such as the temperature or pressure of the water flow from the outlet valve body 7, the water outlet status can be accurately fed back. Combined with temperature detection and water flow detection at the inlet of the wall-hung boiler 1, intelligent control of the boiler's heat output can be achieved, realizing a constant temperature effect in the bathroom and improving the user experience.

[0052] Please refer to Figures 2-4 , Figure 6 In this embodiment, the outlet valve body 10 is also provided with at least one bypass channel interface 123, which connects to the water flow channel. The outlet valve body 10 also includes a plug 124, which corresponds to and is fixedly connected to the bypass channel interface 123 to seal the bypass channel interface 123. It can be understood that the bypass channel interface 123 provided on the outlet valve body 10 is a reserved interface that can be adapted to different installation scenarios, such as heating and domestic hot water, multi-circuit heating, etc. When it is not in use, the bypass channel interface 123 is sealed by the plug 124 to protect the bypass channel interface 123 and prevent impurities from damaging the interface.
